After swapping over to the Benchmark, it was night and day.
Benchmark ahb2 amplifier review full#
knowing the LS50's, with their combination of low impedance and phase angle in the mid bass are a difficult load, I listened to them full range without subs for a day before the Benchmark arrived. With ear up against the tweeters, the Benchmark was deathly silent, even at full volume, unlike the hissy Chord. to acquire an amp with no sonic signature no matter what speakers it was powering, even at high volume levels, in the knowledge that when combined with a good DAC/DSP Pre, what I was hearing was 99% speaker/room acoustics, the recording quality not withstanding. The Benchmark on paper fitted my MO, i.e. Whilst the LS50's weren't running full range, I still wanted the most powerful and transparent amp available to replace the Chord integrated amp I was using at the time. Have you guys tried one and what did you think of it ?Ĭlick to expand.Before going down the active speaker route, I bought one of these from Keith Purite Audio to power some LS50's in a DSP integrated multi-sub setup. I have previously read a review in hi fi critic which in listening tests was not that complimentary. This is what I look for in high-end audio: absolutely the best performance so no second guessing is involved. Using it, you can be assured that any distortion that you hear is from other sources It goes without saying that the Benchmark AHB2 breaks new ground with respect to performance of power" amplifiers. Of course this type of SINAD (signal and noise ratio) crowns the Benchmark AHB2 as the best I have ever tested:" The worst case spike is below -130 dB! This is insanely good. "I hope your jaw is on the floor just like mine was when I saw this picture emerge! 113 dB THD+N in a power amplifier? Are you kidding me? Now the audioscience review mentions some thoughts This next part is where the real magic seems to take place, and is the one that Jayant prefaced in one of our phone conversations with, "You're not going to like this." The next few sentences he spoke to me contained the word "feedback," several times! It is a hybrid amplifier, using a Class A-B design that also employs signal tracking to modulate the voltage on the rails according to the amplifier's actual demand at any given moment. Burdick, who founded Benchmark Media Systems in 1983) uses a switching power supply with rails regulated at +/- 45 Volts. Folks, this isn't a digital amplifier at all it is a linear amplifier built on technology developed and patented by THX Limited, of San Francisco, California. The only word to describe this amplifier is tiny! Measuring just 11.04" wide by 3.88" tall and 9.34" deep, including feet, heat sinks, and binding posts, it weighs in at only 12.5 pounds! The actual amplifier circuit itself fits in the chassis space of only 8.32" by 3.88" by 7.88"! That is slightly less than one quarter of one cubic foot! Do you realize how small that is! So, just how good can such a miniscule Class D amplifier sound? That was my first completely erroneous thought too. Some blurb from a review to give some background They may lack the luxurious edge of other brands but we find the look timeless.Following on from the ayre codex review from audio science i notice he is extremely positive about how it measures.
These devices are indestructible, wonderfully compact and not heavy. The HPA4 and AHB2 have been a fixture in our reference system for several years now and for several reasons. In cooperation with THX came the AHB2 power amplifier and not much later they developed a matching headphone amplifier and preamplifier, respectively the HPA4 and LA4. Of course, it didn’t stop at d/a converters. The latter was our reference for a long time and was only recently replaced by the Sonnet Morpheus. It was soon followed by the Dac2 and Dac3. It was a no-nonsense device that was especially sought after by purists and is still considered a kind of benchmark (pun intended). Their first commercial product, the Dac1, was very well received worldwide. In recent years they have also ventured into the consumer market and with considerable success. Benchmark Media Systems Inc of Syracuse, New-York is a thoroughly American company and has been one of the top pro-audio manufacturers for thirty years.
