DAC2 HGC - "When it comes to D-A conversion, this company is called Benchmark for a reason."
"It ... features a clever hybrid gain control (accounting for the 'HGC' in the product title) whereby analogue inputs are attenuated with a motorised analogue potentiometer, and digital inputs are attenuated by a 32-bit digital attenuator, which is controlled by the same rotary pot. The actual D-A conversion (which can also handle DSD streams) is performed by the latest ESS Technology 'SABRE32' reference DAC chip, in a configuration that differentially sums the outputs of four balanced D-A converters together to maximise linearity, signal-to-noise and dynamic range performance."
"I plumbed the DAC2 HGC into a number of different systems, replacing my usual monitoring controllers (Benchmark DAC1, Grace Design M902, Bryston SP1.7, Crookwood M1) without problem. I listened to a wide variety of commercial material sourced via CD, DVD-A, SACD and Sonus media servers, as well as from my own recordings and mixes on SADiE and Reaper."
"The most noticeable and dramatic sound improvement over all of my other D-A converters was the complete absence of peak distortion when listening to commercial CDs! Most current and 're-mastered' music contains significant inter-sample peaks, and that inevitably cause distortion to varying degrees through clipping of delta-sigma converter filters."
"The original DAC1 was aimed squarely at professionals, but was subsequently embraced by the audiophile market. It remains an excellent D-A converter, and its ability to completely isolate interface jitter sets it apart from most D-As, including some of the much more costly models. However, digital audio technology continues to make incremental improvements, and in the eight years since I reviewed the DAC1 the state of the art has clearly advanced. The DAC2 HGC is undoubtedly a major step forward in technical performance compared to its forebear and, although it costs almost double the price of a DAC1, it does also offer a lot of additional features and facilities."

"The benchmark combination offers a full range of equipment that can hardly be topped, leaves nothing to be desired in terms of sound, and meets professional requirements without any ifs or buts."
"The HPA4 has the HIFIMan one hundred percent under control, eliciting neutral timbres, tons of spatial information and crisp dynamics."
"I connected everything the household had to offer in terms of speakers - Spendor S3 / 5, Ayon Seagull / c, Quad ESL57. It goes without saying that the American coped with the dynamic boxes with ease. But even the quads, which have some meanness on the part of their impedance, did not pose a challenge for the amp."
"There are many things that come into play when putting together a hi-fi system, one of which is synergy."
"After the arrival of the Benchmark Media Systems AHB2, I immediately thought of the matching HPA4 that colleagues Jaap and Yung were very pleased with."
"The key question, of course, was whether the HPA4 would really provide an audible improvement."
"Well you bet! The synergy between preamp and power amplifier is nothing short of magical, not to mention the DAC3 B that I got from importer Helios for the occasion."
"Not only a few curtains disappear, the whole window is gone."
- Geoffrey Vanhouwaert, Alpha-Audio
"The Benchmark AHB2 is a very fine sounding, easy to live with, zero-maintenance power amplifier that has enough power for most systems. If more power is needed, two amplifiers configured for mono can provide it. The decision to purchase the review sample and make the Benchmark AHB2 a new, long term reference took over a month of listening and comparisons."
"The outstanding musicality of the Benchmark AHB2 takes some time to convince the listener of its wholly musical presentation. This subtle excellence assures long term satisfaction."
