The triple-series, triple-parallel output stage was also groundbreaking. Contents. I used my 400 with great satisfaction for nearly five years on Dahlquist DQ‑10s. 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. Said to be the world’s first servo-controlled power amplifier. 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. The Emotiva XPA-2 stereo amplifier. Clean, crisp and clear, the detail resolution was superb, really digging into a recording and laying it bare. Combine that sound with a superb build quality, and you had an amp whose performance could rival pricier options. It was designed by the man whose 550 pure-pentode design was the breakthrough and the basis for today’s best tubed designs. Copyright © 2021 The Absolute Sound. Carver wondered why his home-built big tubed amp of the day sounded much better than solid-state designs. McIntosh MC3500 While the MC2505 put the signature big blue meters in the market, many people consider this the greatest amplifier ever made. It is even a better value used. It was so talented that it gave far more expensive amps a run for their money. If you wanted high-end quality without having to buy separate components, this one-box solution worked a treat. Four may be an even number, but a four-channel amplifier like AudioControl's Avalon G4 might seem like an odd duck to some. It was happy playing all types of music, no matter what type of recording you fed it. 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? Threshold 400A power amplifier. But Hafler could prove by his differential input-output test that the XL-280 was close to perfect and probably did not worry much that high end was largely preferring tubes, which were demonstrably less accurate by comparison. Ever. The Audio Research Corporation needs no introduction. My list of the greatest guitar amps ever! PowerWerks PW50 RMS Personal PA System 50W; 1.2 2. Then there was the 400 that came down the road later, and did at first sound transistory, thus it was subject to the golden touch of modifiers like Frank Van Alstine and became a formidable contender in the high powered solid-state amp sweepstakes. The thing I remember best about them was their incredible purity, both at the tightly defined and taut bass frequencies on up into the, like their designer, ethereal ionospheric regions. Also, not incidentally in Carver’s mind, the 700 came along during the two-channel era when smaller and much, much less efficient speakers (especially the so-called “air-suspension” designs) were in vogue. 's lifetime. Marantz As there must be a Marantz manufactured by Saul on this list, the Model 8 or 9 are the logical choices. Mark Levinson ML2 This John Curl designed amplifier established Mark Levinson, the man, as a driving force in the audiophile marketplace. The very model of neutrality, low distortion, substantial power delivery, and “high definition” (in the midband, not in the lowest bass or topmost treble), it is still highly prized by aficionados and led to the development of ever higher-powered, lower-distortion, higher-resolution, fuller-range designs from ARC, such as the Reference 600 and the current Reference 610T. We've often referred to a stereo amplifier as the heart of a hi-fi system, the rug that knits a system together. An accidental contribution to the 700’s excellent, low-distortion, and uncolored sound: Its biasing transistor sat very near to the unit’s massive heat sinks, so the longer you played it, the better the 700 sounded. This amplifier doesn’t force you to choose between resolution and musicality. (Legend: It could make solid-objects disappear into a nowhere dimension.) Considering its importance, it pays to pick a good one. 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. Anyway you slice it, a conrad-johnson Premier amp belongs on this list (or, at least, my list). $60,000 for an amplifier! It was a popular combination that made up many hi-fi users' systems, and was capable of delivering drive, dynamic punch and powers of organisation that few could match. The 3020 was simply the “go-to” amplifier for an entry-level high-end system. 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. This issue was not a problem for its successor, a "supremely stable, confident-sounding" amplifier that boasted excellent bass performance and surefooted rhythms. There may have been amplifiers that sounded as good, but none had the mix of sound and features at such a competitive price. About which there was some controversy, particularly from other designers, who thought Pass had pulled a sleight of hand. Pioneering? And they still are. Marantz Model 9 monoblocks Along with its less-expensive, lower-power, stereo brother, the Model 8B, Saul Marantz’s legendary Model 9 was the best tube amp money could buy back in the 1960s. Citation Two I have chosen just one of Stewart Hegeman’s many amplifier designs. Dennis Had’s Cary CAD-805 was the amplifier that put SETs on magazine covers. And he thought, at the time, that the high-voltage output was the decided advantage tube designs had. It was designed by Bobby Carver, one of the brightest and most innovative thinkers ever to grace audio. McIntosh Tim de Paravicini has said that the only audio circuit apart from his own he wished he’d designed is McIntosh’s “Unity Coupled Circuit.” Of several obvious contenders, my choice is the MC275—introduced in 1961, designed by McIntosh co-founder Sidney Corderman—one of the first tube amps to sound truly neutral and offer high power (75 watts/channel, very high those days). Its 375 watts per channel, four gleaming chassis, and 15 KT88s per side (14 as outputs) were mind blowing. Nevertheless, it was the sound that gave the GSi75 distinction. Dynaco ST-70 It matters not which David Hafler amplifier is chosen so long one Hafler is here. Each 88-lb XA60.8 operates in pure class-A, made possible in part by the amp's massive aluminum heatsinks and no-less-massive steel mains transformers. BoyuuRange MT-34 MKII. Typical used price: $500-$700. There were other designs that did not quite materialize either, including a strain-gauge cartridge/preamp. PRO-JECT STEREO BOX S. Price: £199. A 70W (40W in switchable triode mode) monoblock, it set the standard for liquidity and gorgeousness of timbre in its day—and to some diehards still does. )The ML-2 worked best as a mid-range amp, and its virtues show to fullest extent on an electrostatic (it was designed, it is said, for the Quads). It had a sense of clarity, detail and insight without ever coming across as sterile, edgy or harsh. The future had arrived, or at least one version of the future. 7) Kenwood KAC-M1804 Compact – Best Amplifier for Marine Applications; 8) Rockford Fosgate PBR300X4 300 Watt Ultra-Compact – Best heat management amp; 9) Power Acoustic RZ4 -1200D Class D 4-Channel amplifier – Most Powerful Small Amplifier; 10) Crunch PX-1000 Car Audio with amp wire kit- Best Amp with Kit Threshold 400A power amplifier. Check Latest Price. The 800A was the first product in a lifetime of creative approaches to amplifier design that continues to this day in Pass Labs’ products. Number of units # Unknown - 1 to zero made Nonetheless, this is the greatest Stax Amp ever created. Phase Linear 400 Introduced in 1972, this 200Wpc stereo amplifier from the redoubtable Bob Carver was perhaps the first big solid-state amps to offer high power without the usual price tag in grainness and odd-order harmonic roughness. It worked well with all genres of music, with no trace of boom or bloom, and a clarity that extended throughout the frequency range. He learned, through his measurements, that tube amps could swing 200 volts, while their solid-state counterparts only 35 or so. Introduced in 1967, it is nearly the only early solid‑state amplifier that gave and still gives the lie to sweeping assertions about early transistor amps’ grain and harshness (thanks to Walker’s innovative use of “output triples,” which made the 303 unconditionally stable). Its life span was extended for a few more years by New York Audio Labs. 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. NAD 3020 Since the criterion is “significant,” the highest‑selling integrated amplifier ever made—introducing NAD’s famous “soft‑clipping” circuit—must surely qualify. Having already designed a world-class preamplifier—the highly acclaimed $7100 K-1 (see Wes Phillips' review in March 1997)—Hansen set out to offer audiophiles "80 to 90%" of the K-1's sound and build quality at a price more of them can afford.Not that the new K-3 is a piece of "budget" gear. The One communicated a precise soundstage, but it was also capable at handling low-level details that other amplifiers "repressed or simply rendered messy". 1 List of 10 Best Keyboards AMP on the Market Today:. Alpine PDR-V75 5 Channel Amp. The best 30 hi-fi speakers of What Hi-Fi? Peavey KB 1 20W Keyboard Amp; 1.4 4.

McIntosh MC275 A 75Wpc stereo amplifier, designed primarily by Sidney Corderman in 1961. 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. Whether you listen to jazz, rock, rap or whatever really, the addition of a quality subwoofer will bring a level of power and definition to your music that no speaker could ever reproduce. 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. Maybe he simply fed himself into his force-field speaker.). The sound had a "clear and dramatic" balance, with instruments and voices having a striking presence in the soundstage. The Premier One, however, got these basic frequencies right and more importantly, their resulting harmonics. The DH-200 made a high-end powerhouse amplifier affordable to many. What we do know is that the XPA-2 passed our test bench with flying colors, and delivered sound quality that made us question the need to spend more. This Naim came in three parts, with the 32 pre-amp, its accompanying power supply and the now legendary 250 stereo power amplifier. Roland KC-110 3-Channel 30-Watt Stereo Mixing Keyboard Amplifier It was a well … Britain's Naim Audio Ltd. is best known for its amplifiers and CD players, but this new speaker breaks a lot of rules and sounds less like a box speaker than anything on the planet. With Bluetooth and a phono preamp on board, … 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. Krell Dan d’Agostino’s pioneering work in Class A amplification must be recognized, though I’m uncertain which model—the KSA 100, perhaps? And the sound was terrific, offering a measure of control and composure, with high levels of detail along with a fluid and refined presentation. The best stereo speakers are an essential part of any audiophile's home setup, even if standalone wireless speakers like the Apple HomePod and the Sonos One are all the rage right now. Vox made an about $80 amp that too many people say sounds just as good. If you’re looking for a stereo amp to handle a turntable, and you like your audio to have some real weight to it, the PMA-600NE is the one to pick. JBL Crown A6000GTi — In 2004, a “big” car audio amplifier made 1,500 watts. Contents. David Hafler oversaw many amps later on, including the Stereo 120, which I thought the least transistory-sounding solid-state of its 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. Dynaco ST-70 Along with Avery Fisher’s 500c, David Hafler’s ST-70 put high performance audio in the American home. Audio Research Reference 610T In the late 1960s, William Zane Johnson, began building and selling modified (Dynaco) ST-70s. The build and finish were excellent, it was easy to partner with and, while its distinctive look caused some consternation, there was no doubting its status as an exceptional performer. Thus, it had a hard-to-define (then) quality of naturalness, call it rightness, that made it unique. User Interface: The amplifier needs to be user-friendly for easy set-up and control. 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. 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. 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. These were designed by Sid Smith (of Sea Cliff, no less) under the watchful eye of Saul Marantz, who was always in and ahead of the vanguard of state-of-the-art sound (from his marketing of the first straight-line-tracking arm/turntable—a commercial failure—to his early sponsorship of Jon Dahlquist and the DQ-10 speaker). A power output of 20W per channel wouldn't have turned many heads, but the 3020 could drive speakers better than pretty much any of its rivals. We weren't fully convinced by the original Supernait, which sounded less dynamic than we liked. It was a well-equipped amp, with a decent array of line-level inputs and a capable moving-magnet phono stage, and we were very much taken by its sound quality back in 1979. Klipsch Forte III: Powerful towers with impressive flexibility. Rotel RB-1090 Blue plate manna from audio heaven, the RB-1090 was the go-to amp for low-sensitivity speakers that presented tractor-sized loads. It is warmer and darker than pure neutral, and it also blunts transients, but it can be improved in the areas of neutrality, transparency and speed with better coupling capacitors. There was one made but it is only 100 watts per channel I believe. I could have chosen several other Pass designs that would be worthy of this list. McIntosh 275 This is a legendary amplifier, and from a legendary company, whose commitment to quality of construction and design has never wavered, not even during its long dark night of solid-state electronics. Completely devoid of grain and grit, the Reference 600 was revelatory in its seductive liquidity. 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). It was a small, beautifully made integrated amp that boasted an output of just 10 watts per channel. Historically important. The Best Around $1000: Cambridge Audio CXA81 Integrated Amplifier ($1299). Did I forget to mention the heat it generated and the number of tubes that failed? NAD 3020 Stereo Amplifier. Phase Linear 700 One of the first high-powered blockbuster amps of the modern (read: high-end) era. Newer, tougher competition eventually ousted the Primare, but its sound and superb build meant it remained an excellent choice.
