NAD 3020 Since the criterion is “significant,” the highest‑selling integrated amplifier ever made—introducing NAD’s famous “soft‑clipping” circuit—must surely qualify. And that wood finish was, indeed still is, rather lovely. Not the first class-A power amplifier from amplifier shaman Nelson Pass, but believed by many to be one of his best. Fender 5E3 Deluxe. The remote is terrible – … Citation Two  I have chosen just one of Stewart Hegeman’s many amplifier designs. And they came with fabulous rosewood or walnut cabinets. What we love:‌ The CXA81, with its Class AB amp section, drives speakers down to 4‌ Ohms with 120W per channel RMS, and 80W‌ per channel RMS‌ into 8 Ohms. From its tasteful finish to the masses of power it delivered, this was an accomplished amp that could work well in a wide range of systems. Yes. The heat was too much for the amount of time I have my music on during the day. Elikliv Amplifier Home Audio, Stereo Audio Amplifier 2.1 Channel, 5.0 Wireless Blutooth Mini Hi-Fi 2x50W Home Passive Speaker Output 1x100W Sub Output with Sub Bass Treble and USB Port Remote Control And the Carver A Series, designed by Jim Croft, had the all but unique feature of no output network, for flat response into any load at all. I heard it at its best as the central speaker in Levinson’s massive HQD speaker system (H: Hartley, the woofer; Q: the midrange Quad electrostatic; and D: Decca ribbon tweeter), awesome in its day and an inspiration for the creation of the QRS-1D. And, simultaneously it also got the dynamics right—yes, the other units could play midbass notes at the loud end of the ffff spectrum, but not fully at both ends, including the softest. Phase Linear 700 Although not nearly as popular as the smaller 400, the 700’s claim to fame is that it was the first truly high-powered amplifier. Heathkit amps  A right of passage—there was more hair pulled out trying to finish these DIY amps. Detailed, neutral, and transparent, the Phase 400 may not have generated all the wattage/voltage of its elder and bigger brother, the highly regarded Phase 700, but to some of us it sounded more lifelike in timbre and texture than the bigger PL. He learned, through his measurements, that tube amps could swing 200 volts, while their solid-state counterparts only 35 or so. Quad 303 Nice as Quad’s tube designs were, Peter Walker’s real breakthrough was the 303. Best Amp for small rooms – PS Audio Sprout100 Lets breakdown each one shall we: 1. There were other designs that did not quite materialize either, including a strain-gauge cartridge/preamp. Ran mine as a pre-amp to a McIntosh 2505 but used the onboard 15 watt amp to run Stax headphones. The result Is better than when I first bought the Troughline, now I know why this Troughline/Paravicini combination has been described as probably the best sounding stereo tuner ever made, it has an incredible open, fast and spacious soundstage indeed very natural sounding only on compressed broadcasts is any male chestiness apparent. Introduced in 1977, these 25W Class A monoblocks (50W into 4 ohms, 100W into 2 ohms) from Mark Levinson set a new standard of clarity, liquidity, timbral beauty, and three-dimensional imaging and soundstaging for solid-state. Unique for its time were the transformers and output transistors placed on the outside the chassis–an innovation that eased serviceability and reduced operating temperatures. So, it was said only a few units were left over for Iverson to sell to the general public. One of the most natural-sounding phono amps we've heard, unleashing a great amount of detail, it shone no matter what music was being played. There may have been amplifiers that sounded as good, but none had the mix of sound and features at such a competitive price. We weren't fully convinced by the original Supernait, which sounded less dynamic than we liked. McIntosh MC275  Using an implementation of Mac’s original unity-coupled circuit, the MC275 set new standards for low distortion. McIntosh MC275 A 75Wpc stereo amplifier, designed primarily by Sidney Corderman in 1961. Mark Levinson I have no experience with Levinson products, but surely a list like this must include one—the 25 watt Class A ML2 perhaps? The Reference 600 combined this exquisite delicacy with iron-fisted dynamic authority. (It also happens that as a very young man I tried to build one of these from its kit version, to drive my acoustic-suspension speakers. Hafler DH-200 Sold as a kit or fully assembled ($299/$429 in 1980, if memory serves), the DH-200 represented the confluence of great sound (thanks in part to a wonderful MOSFET output stage), high reliability, and a dirt-cheap price. Krell's KAV-400xi was described as an entry-level amplifier, though its £2700 price might cause some to rethink the definition of that term. Its many latterday descendants include the marvelous and still-very-much-with-us Air Tight ATM-3. While you can get custom shop amps that hover north of $2,000, you can also dip into the sub-$200 space for a perfect beginners-friendly practice amp with Fender quality. Capabilities beyond the wildest dreams of decades past. Refined into the 610T (tall), it’s 600 watts of breathtaking thermionic power that has no peer. Hi, most of the Kenwood models labeled KA were amplifiers rather than stereo receivers and this list only dealt with receivers. EAR Yoshino 509 The major innovation is Tim de Paravicini’s balanced bridge mode output stage, in which the plate, screen grid, and cathode are assigned their own separate windings on a bifilar wound output transformer.

There was a problem. MORE: That Was Then... A&R Cambridge A60 (1976) vs. Arcam A19 (2013). The Emotiva XPA-2 stereo amplifier. Vox made an about $80 amp that too many people say sounds just as good. Audio Research Corporation Reference 610T monoblocks The culmination of William Zane Johnson’s glorious career as an amplifier designer, the 600W+ 610T is the best ultra-high-powered pentode tube amplifier JV has yet heard—a paragon of neutrality, resolution, transparency, bloom, dimensionality, and seemingly limitless power from the bass to the treble. We recognise 19 of the best stereo amplifiers to have made their way through our test rooms. Back in 2013, we remarked that there was nothing quite like Burmester's 808 Mk5. Even the best solid-state designs could not then reproduce the three dimensions, the depth, of a real-world soundfield, much less its width, and reproduce these with something like the full range of dynamic contrasts. Audio Research D150 The ARC D150 represented a turning point in tubed amplifier design at its 1975 introduction. Though dark and euphonious in tonal balance (the 8B was arguably more neutral), the Model 9 was and is so beautiful that many listeners forgive it its colorations. It had a balance that was smooth and full-bodied, which worked well with the less than refined budget kit of the time, delivering a good, coherent sound. Check out for the best amplifier with an intuitive front panel and easily accessible buttons. Perhaps the quality of “authority” here that was distinctive and that so impressed me lay in the basics. (Legend: It could make solid-objects disappear into a nowhere dimension.) Carver wondered why his home-built big tubed amp of the day sounded much better than solid-state designs. Add its fine build and features and the 8000A was great value for money. Released in 1968 (as the MI350) for commercial applications, it eclipsed any amplifier of the day with an extraordinary 350 watts per channel. Still, distinctive looks aside, it offered excellent sound and features including bass and treble controls, a stereo balance control and a separate record selector, so you could "listen to one source while taping another". Such type of amplifier will perfectly amplify the floor standing speakers and bookshelf speakers. The Fender Twin is one of the best clean tube amplifiers that has ever been made. If you’re looking for a simple, affordable option to get excellent stereo sound, the Sony STR-DH190 is your best choice in a stereo receiver. His best, IMO, was the Hafler DH‑200, but his most significant was the 70, which enabled of thousands of audiophiles to enjoy superb reproduction at budget prices in the early days of stereo and for a good while thereafter. Muzishare X7. MSRP: $1,599/each Though it has recently been replaced by the ML-2.2, which judging by its showing at this year’s CES is even better, the ML-2 was for more than a decade not just the best SET but the best low-powered amp on the market. So a 30-watt/channel RMS stereo amplifier became a 60-watt/ch peak amp, which became a 120-watt IPP amp. I’m not too familiar with the KA-1000. However, this amp is made by Denon, so some design features are practically baked in. The heat was too much for the amount of time I have my music on during the day. Phase Linear  Carver the man and the company would produce better amplifiers later and more powerful ones, too, but the Phase Linear 700 and the more popular 400 were the amplifiers that put high power on the map. Visit our corporate site. Since it is compact in size, the installation options are versatile. Those watts were clean, clean, clean and analytic in a way other solid-states weren’t. The brains and brawn behind your hi-fi. Sanders Magtech Not around long enough yet to have had much influence, but give it time. Anyway you slice it, a conrad-johnson Premier amp belongs on this list (or, at least, my list). Threshold 400a  The follow-up to the Threshold 800, a not-easy-to-find big amp that introduced Nelson Pass as a coming star in the field of audio. Marantz As there must be a Marantz manufactured by Saul on this list, the Model 8 or 9 are the logical choices. Part of the trick was its use of an extra dose of Class A bias, lack of compression, and superb channel separation. Best I have heard or owned. Dynamics contrasts, those going from microsoft (not MSNBC) to very loud, are the defining characteristic of the real thing. Thank you for signing up to What Hi-Fi?. The woofer is made out of the company’s custom Continuum material, which it says improves audio performance by allowing sound waves to pass through it more easily. For experienced listeners, the 150 was such an overpowering (literally as well) experience by contrast, that its audible flaws were overlooked (highly colored bass, overly romantic midrange colorations, and a drooping top octave). Built in a tiny chassis, spanning 40x100x100 that you could easily hold in your hand, the Stereo Box S still manages to pump out 25W of power. One hundred watts of pure class A power with the coolest power indicators you’ll ever see. Technical Brain TBP-Zero monoblock Along with the Soulution 700, this 350W Japanese monoblock from designer Naoto Kurosawa is a poster-child for the New Age in high-resolution, low-distortion solid-state amplification that, for some of us, has wiped away any lingering prejudices we’ve had toward the transistor. 1 List of 10 Best Keyboards AMP on the Market Today:. While there has been an improvement in power output capability, they are much smaller than previous models, which is a win-win on both counts. Number of units # Unknown - 1 to zero made Nonetheless, this is the greatest Stax Amp ever created. The 3020 amplifier put the NAD brand on the map, such was the impact it had. The polar opposite of the grainy, piercing, high-in-odd-order-harmonics sound that many of us then associated with solid-state designs, the ML-2 proved that the transistor could make music as readily as it could generate power. In 1995, Johnson designed his lifetime achievement product, the Reference 600. JBL Crown A6000GTi — In 2004, a “big” car audio amplifier made 1,500 watts. It had no tone or balance controls and carried plenty of inputs for sources. Dynaco ST-70 Insanely popular, the David Hafler designed 35Wpc was introduced in 1959 yet kept on truckin’ for about 30 years. This Naim came in three parts, with the 32 pre-amp, its accompanying power supply and the now legendary 250 stereo power amplifier. Krell Dan d’Agostino’s pioneering work in Class A amplification must be recognized, though I’m uncertain which model—the KSA 100, perhaps? It worked well with all genres of music, with no trace of boom or bloom, and a clarity that extended throughout the frequency range. The amplifier was, to me, an astonishment in the form of sound.) It wasn’t a Stereo 120 or a Phase Linear 700 though. One of the truly great, pioneering solid-state designs, the KSA-50 was perhaps the first solid-state amp that could be justly called unflappable. Krell KSA-50 The KSA-50 is significant more for being the first commercial product from then-newcomer Dan D’Agostino and Krell Industries. Krell KSA-50 monoblock Dan D’Agostino’s dark, delicious, 50W Class A monoblock from the early 80s brought something to the table that we hadn’t gotten in quite the same way before: bass! In reviewing Pass Laboratories' solid-state XA60.8 monoblock amplifier, JCA echoed JA's earlier published response to the amp's predecessor, the XA.60.5: "the best amplifier I've heard." It was designed by the man whose 550 pure-pentode design was the breakthrough and the basis for today’s best tubed designs. There are many more audiophiles today because of the 3020. Roland Cube Monitor / PA; 1.3 3. The Caspian amp had been around the block a few times, as Roksan improved the design and performance. The circuit sounded so good that many of today’s tubed amplifiers are based on the ST-70’s fundamental topology. Phase Linear 700/400 Bob Carver’s 1970 designs demonstrated that mega-amps driving lower-sensitivity loudspeakers could perform on the same field with lower-powered competitors. In 1988, Hiroyasu Kondo’s, minuscule-powered, 27Wpc SET integrated amplifier set the mark for luxury pricing of audio components. These amps were built during the 50s (yep, the 1950s) but can still be found in full working order. It’s still a reference for many collectors when recapped (including me). the last two digits indicate watts/ch. The Absolute Sound’s Buyer’s Guide to Loudspeakers 2018. The triple-series, triple-parallel output stage was also groundbreaking. Quad 303 Not the first transistor amplifier, but arguably the first to show that transistor amplifiers could sound as good as, or indeed better than, tube amplifiers. The 2nd best Stax amp ever created is the DIY T2. Peavey KB 1 20W Keyboard Amp; 1.4 4. What Hi-Fi? So it makes sense for this issue to include an Audio Research review—in this case, of the $20,000 Reference 160 S stereo amplifier. Levinson help to raise the bar on resolution and power and cost and led the way for dozens of wannabes. Plinius 8150  The 8150 represented the leading edge of a new breed of high-power integrated amplifiers that challenged the hegemony of separates. Year: 1978. Cary Audio Design 805 This amp more than any other is responsible for the commercial success and revolution, if you will, wrought by single-ended triode designs in the early 90s. I also remember that it was one of the rare electronic components that even “measurements tell everything” reviewers admitted sounded better than others measuring equally well. I could have chosen several other Pass designs that would be worthy of this list. Roland KC-110 3-Channel 30-Watt Stereo Mixing Keyboard Amplifier Iverson was also legendary for developing a “force-field” speaker that, it is said, the military had its evil eye upon for some dark purposes.

Audio Research Reference 600/610T The forerunner of the 610T, the massive Reference 600 (34 tubes per side) not only set a new standard in timbral purity and realism, it opened my eyes to the virtues of tube regulation (6550’s as the series-pass elements). Audio Research Corporation D150 Singularity. New York, Marantz 8B One of many, now legendary designs from Marantz audio engineer Sid Smith, the 8B can be considered the amplifier (35Wpc) that contemplated the modern era of the high end. The consumer version, MC3500 established McIntosh as the premier audio company of the day. The Williamson Amplifier (1947-1949) Not the first tube amplifier with feedback nor the first with low distortion—Peter Walker had a feedback prototype in the late 1930s and Leak a hi-fi amp before Williamson—Williamson’s designs published in Wireless World in the late 1940s showed once and for all that low-distortion amplification was possible and practical. Marantz 8B Introduced in 1962, this Sid Smith design represented the pinnacle of Class A Ultra-Linear design, delivering a sweet 30Wpc from a pair of EL-34 power pentodes operating in fixed bias. PRO-JECT STEREO BOX S. Price: £199. The sound had a "clear and dramatic" balance, with instruments and voices having a striking presence in the soundstage. Runner up amplifier – Cambridge Audio CXA61 3. Still in production today in its Mk IV version, this is an authentic classic.

We picked the Sony STR-DH190 as the best stereo receiver because it offers the best mix of features, sound quality, simplicity, and affordability. Audio Research Corporation D150 Preceded by the superior D75, D76, and D76A stereo amplifiers, this 150Wpc, 6550-based behemoth was the culmination of William Zane Johnson’s “first-generation” tube designs. While the MC2505 put the signature big blue meters in the market, many people consider this the greatest amplifier ever made. Dynaco ST-70  It matters not which David Hafler amplifier is chosen so long one Hafler is here. It was an impressive combination and the 250 has proved to be so popular that it's received several makeovers since, getting better with each iteration. Newer, tougher competition eventually ousted the Primare, but its sound and superb build meant it remained an excellent choice. Phase Linear 400 Bob Carver’s 700 was higher powered and came first, but the 400, released in 1972, was the real beauty of the early super powered amplifiers with high output voltage swing. Threshold 800A Nelson Pass’ first power amplifier under the Threshold name (1975), the 800A signaled to the world that Pass was a designer of uncommon talent and original thinking. That is, Johnson had got the midbass right, which, to this point, no tubed amplifier had done. It was a small, beautifully made integrated amp that boasted an output of just 10 watts per channel. 1.1 1. Best overall amplifier – Peachtree Audio nova300. This, our February issue, is the first Stereophile issue to arrive during the year 2020, which marks the 50th anniversary of the founding of Audio Research—in my view one of the key events in the history of high-end audio.

The audacity of the “Carver challenge” still fresh in the public mind, he shocked the world with the most expensive ($17,000) and esoteric conventional tube amplifier ever (till then). Mark Levinson ML2 This John Curl designed amplifier established Mark Levinson, the man, as a driving force in the audiophile marketplace. Said to be the world’s first servo-controlled power amplifier. What made it an interesting product, aside from its unusually smooth sonics, was the fact that it was called a Class A (high-powered) unit. After the sale I had to find a new amp so away I went to audition a few. Mark Levinson ML-2 monoblocks The little-known and underrated Hadley Laboratories 622C aside, this was the first solid-state amp I heard to put the transistor on an equal footing with the tube. Introduced in 1948, the Fender Deluxe was praised for its dynamic, harmonically … The 400 would go into Class AB if the sonic demands exceeded its capabilities (said to be a rarity). It spoke with a kind of dynamic truth that was undeniable. Harman Kardon Citation 12 I will never forget the first time I laid eyes on the 12—it was the coolest and one of the most serious looking amplifiers I’d ever seen.
