That said, folks trying to drive the Hifiman HE-6 and Susvara gravitates towards this piece of gear. There seems to be an interest in it for hard to power headphone enthusiasts on the forum even though Benchmark makes the HPA4 which is a headphone amp. THX patented feed-forward error correction / THX-AAA technology The Benchmark AHB2 is a power amp meant to power speakers. Up to 29 A peak parallel on each channel There are many positive reviews about it. Incredibly beautiful, high-quality amplifier. Includes original box, cables and documentation. Only used for a few months and therefore has 0 signs of wear or damage and works fully properly. Recently sold 1 and decided to also offer the 2nd because it is not actually being used at the moment and I have another amplifier for the set I have. This compact, lightweight, cool-running, class-AB power amp is a real breakthrough in every way.For Sale: Benchmark Media AHB2 Black (Linear Stereo Amplifier).īought 2 of these amplifiers at the end of last year to try out a larger speaker set before purchasing, but I decided not to buy the speakers. Yes, I could hear the differences between the different amplifiers, and that's the point. It was a great pleasure, as old friends, some already mentioned, smiled anew. "As time passed and I listened more, I grew to love the AHB2's sound, and undertook the rewarding effort of listening through it to as many different recordings as I could. The bass had all requisite extension and detail (see above), but seemed to be more naturally balanced with the rest of the audio band." Now the treble wasn't so much un-bright as smoother and unaccented.

"At first, I thought the AHB2 sounded less bright, and less full in the bass, than the other amps I had on hand, but after only a few days of listening I began to accept that it sounded more "right" than any of them. "That seemed to present no problem for the AHB2. I had to push the AHB2 to unreasonable and personally uncomfortable volume levels to get the least blink from one of its Clip LEDs" there are current-hungry combinations of 4 ohms and –52° electrical phase angle at 62Hz and 5.3 ohms and –39° phase angle at 8.6kHz." At an SPL of 90dB, the B&Ws are of neither particularly high nor low efficiency, but JA has told us what makes them difficult to drive. It was clear that this 100Wpc (into 8 ohms) stereo amp had all the power needed to drive with aplomb my Bowers & Wilkins 800 Diamond speakers to any reasonable level. "In addition to quantity of soundstage detail, the AHB2 was also "large" in power output. "These surprising and delicious details were evident from the bass up through the midrange and extreme treble, which nonetheless remained silky and diaphanous." In many ways, the AHB2 is a complete 180 degree departure from traditional high-end amplifier designs. This made a much greater impression on me than any subjective awareness of a lower noise floor, per se." The performance of the AHB2 would not have been achievable without taking a radical approach to power amplification. I suspect that, being newly informed of their existence, my ear/brain could more easily extract those details from the output provided all along by my other amplifiers. I qualify that statement with apparent because, after hearing the AHB2 uncover previously unheard subtle details, I found I could now hear them when I returned to my other amps.
it was probably the AHB2's low noise level that revealed to me much more apparent low-level detail in already-familiar recordings.

"These features, along with the detailed manual and specs included with the amp, suggest that the AHB2's target market is the audio professional or the recording studio." A third Neutrik NL4 is provided for use when the amp is in bridged mode, which is selected with a second toggle switch." Calculate the combined system performance of a Benchmark audio system using a DAC3 D/A converter, LA4 line amplifier, and AHB2 power amplifier. For output, the Benchmark amp offers a choice of traditional multiway connectors or a stereo pair of Neutrik NL4 sockets.

I was also impressed with a seriousness of design apparent in its features: The fully balanced AHB2 has, on its rear panel, only XLR jacks for signal input, plus a toggle switch that allows the user to select among three input-sensitivity levels. The TPA3255 amp has an intrinsic 22dB of gain, so the setting from the. The Texas Instruments OPA1656 operational amplifier’s buffer has a DIP switch, which can be set at 0dB, 6dB, 14dB, and 20dB. "When I unpacked the AHB2, I was impressed with its small size and weight: the non-rack-mount version is 11.04" wide by 3.84" high by 9.34" deep and weighs only 12.5 lbs. Like most basic power amplifiers, the Warp 1’s exterior has no adjustments, but inside the chassis users have several choices for overall gain.
