Boasting classic circuit designs by renowned engineer John Curl and prices that range from just under $1000 to a few … I can order them online and return the one's I don't like, but that gets tedious. such a powerful amplifier. this amp doesn't suffer from slew induced distortion typical of lesser Parasound seems to have attended to every aspect of their design including the The A 21+'s distortion was predominantly the subjectively innocuous second harmonic (fig.7), and higher harmonics are all very low in level (fig.8). Stereophile has also reviewed the PS Audio Stellar M700. I will have to take a gander at my local dealer. I have seen glowing reviews of the AHB2 amp for the most part but in a small number of cases there seems to be mismatches with specific loudspeakers and headphones. I actually purchased my A21+ from them. The modulation of the amplifier's frequency response, due to the Ohm's law interaction between this source impedance and the impedance of our standard simulated loudspeaker, was therefore minuscule, at ±0.1dB (fig.1, gray trace). Food for thought? Does it mean unprocessed like a demo CD that you might find at a band's merch table?

The statement merely acknowledges that RR recordings are known for their wide dynamic range (R128 dynamic range is 22.2LU on the track discussed) and that they are often chosen to demonstrate that at audio shows. any speaker load in even the most demanding home theater systems. Shipping to United Kingdom. If you happen to be searching for a 7 channel amplifier then we As Parasound defines it, value begins to decline when additional cost provides only marginal and diminishing returns, and increases when a product is reliably functional over decades. numbers are weighed heavily with respect to the They amp at +/- 3dB from 5Hz to 100kHz at 1 watt. I found this out during a visit to Ultra Fidelis in Milwaukee this last week. If you run into difficulties, the Troubleshooting Guide should help you quickly remedy the problem. The unbalanced input impedance was 46k ohms at low and middle frequencies, 37k ohms at the top of the audioband. The only problem that I had was with an AHB2 with the Monitor Audio Silver 8s in my CT system and I have not tried them with the monoblocs. I would anticipate(!) - Parasound A21+ Tilføj til kurv.

Parasound Products was founded in 1981, in San Francisco, by Richard Schram, whose mission was to provide value for the money to his customers. ...a larger (apparent) soundstage, then try a tube amp. @zerodeefex warned me about the Parasound amps. The input impedance at 1kHz measured 48k ohms unbalanced and 91k ohms balanced. as you will not be disappointed in your investment. ), something the A21+ above avoids completely, due to its far greater power capabilities. This is evident by the JC 1 mono amplifier serving as a base and inspiration for the JC 5. I no longer have the Revel Performa F228Be but I bought a pair of the Revel Performa3 F206 speakers for surround channels, primarily. it. Thanks, may be more boxes than I'd like to deal with. The A21+ results look worse (to my eyes) and also distortion seems to be higher than that of A21 in my measurements. One can pop the feet off and use the supplied mounting kit to secure the A21+ into a standard 19 inch wide audio rack where the mounting height will be four rack spaces. The Parasound's output impedance was a very low 0.077 ohm at 20Hz and 1kHz, increasingly slightly to 0.1 ohm at 20kHz. Which one to you keep connected to the speakers, and why ? The response into an 8 ohm resistive load (fig.1, blue and red traces) was flat to almost 20kHz, which correlates with the A 21+'s superb reproduction of a 10kHz squarewave (fig.2). Measured with the unbalanced inputs shorted to ground, the amplifier's unweighted, wideband signal/noise ratio was 78.1dB ref. The Parasound A 51 amplifier is more than capable of driving Note: Measurements can be found through this link. I … Well, it would have to be hypothetically because, although I have used most of these these components before (not the A21), I have not used any two of them at the same time or A/B. will deliver marginally close to its rated power into 4 ohms.

I tried to tell my wife I was gold/silver color blind but it didn't work. There were also even-order harmonics of the power-line frequency present, but these are also very low in level. Of course this all assumes you Specifikationer. Fig.1 was taken with the balanced inputs; the response with the unbalanced input was identical, though in bridged-mono mode, the output at 20kHz was down by a still-trivial 0.25dB, due to the doubling of the amplifier's output impedance in this mode. They currently have the 3b3 on sale for $5215.50 while the A21+ is $2995. Similar power and price. Thank you! maybe even listen. Mar 11, 2017 #3 It was sold as faulty . If you notice better performing products in future reviews that have lower numbers There's no where I can go to listen to all the different amp options with a specific speaker model.

I don’t know where you are located but AudioAdvisor is a US online dealer for both Bryston and Parasound. Using our definition of clipping, which is when the output's percentage of THD+noise reaches 1%, the Parasound easily exceeded its specified powers with both channels driven with a 1kHz signal. I have not heard/used the M22 v2. If this amp is 10% "better," that number is not worth testing the waters of diminishing returns. Although price isn’t indicative of which would be better, a 3b3 for only $400 more than the A21+ sounds like a better deal. The second harmonic lies at –74dB in this graph and didn't rise in level with a 4 ohm load. Copyright © 1998–2020 Audioholics, LLC. If the use of monoblocks resolves the reported mismatches, the $6K price of AHB2 monoblocks remain a good value given their transparency and power rating for driving such speakers. The new variant A21+ now has been developed with enhancements (both cosmetic and more fundamentally - internally) by the dedicated team at Parasound, to ensure that where necessary the natural development of benefits can be added … At the end of this time, the side-mounted heatsinks were very hot, at 162.8°F (72.7°C). Ken Stein is a contributing writer and reviewer for Audioholics and he really REALLY likes his speakers (which he should, since he spent countless hours hand-crafting them himself.) well done. “Let our rigorous testing and reviews be your guidelines to A/V equipment – not marketing slogans”. (With a class-AB output stage, one-third power results in the maximum dissipation in the output devices.) The Parasound A 21+ offers a lot of low-distortion power and isn't fazed by impedances as low as 2 ohms.—John Atkinson. Please note that during the 4 ohm load test, my wall I also read elsewhere that if the amp sees tough loads with large voltage swings, there will be issues with amp coping (perhaps the reason Herb's review of the amp with the RAAL headspeakers was unenjoyable? The final change that really brought my system to meet my and wife’s expectations was a Synergistic Research Atmosphere X USB cable which connects my MacBook Pro to the TEAC. equipment doing the duty it is designed for.

Contributor Banned. Notify me before the end of the auction. dealing with sound reinforcement applications may thirst for more power, but NAD M22 is a pretty good, powerful amp ........ Why you want to change it? usually at the expense of higher noise and distortion. the frequency response linearity of the power amplifier within the audible range Bryston 3B3 is high on my list, but considerably more expensive. Interesting. Parasound … from audible noise and distortion makes it a true winner! Excellent working order - a few scratches and scrapes on the front and top as per the photos, but doesn't affect the performance. Additionally, Parasound's A21 just won an … Channel separation was excellent, at >90dB in both directions below 2kHz, declining to a still-good 72dB at the top of the audioband. Thank you so much for the hand. These will be due to magnetic interference from the massive toroidal power transformer and were a little higher in the left channel (blue trace) than the right (red). Hi all, I can see that the left channel of my Halo A21 goes slightly warmer than the right one - difference not too prominent, but still detectable even by a naked hand. A slight 0.35dB channel imbalance in favor of the left channel (blue and cyan traces) can be seen in fig.1, even though the level controls for the two channels had both been set to their maximum positions. The balanced input impedance was high at 90k ohms at 20Hz and 1kHz, dropping to a still-high 84k ohms at 20kHz. eBay See price. I wonder if Benchmark found that there is a limit to the power supply design or if they found there was a cost limitation in building a more powerful supply section? Again, the levels of the distortion harmonics didn't rise when I kept the output voltage the same but reduced the load impedance to 4 ohms. I measured approx. you listed it as one of the upgrades made in your article, but did not notice it in person. heck, forget that conditional: I am greatly impressed with the Emotiva XPA-5.".
