DAC2  HGC Review - Hugh Robjohns, Sound On Sound

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."

AHB2 - Class A Recommended Component - Fall 2018 - Power Amps

'Class A' is Stereophile's highest classification for recommended components. Very few components receive this elite classification. Stereophile defines 'Class A' as follows:

"Best attainable sound for a component of its kind, almost without practical considerations; "the least musical compromise." A Class A system is one for which you don't have to make a leap of faith to believe that you're hearing the real thing."

DAC3 HGC - Class A+ Recommended Component - Fall 2018 - Digital Processors

'Class A+' is Stereophile's highest classification for digital processors. Stereophile defines Class A and the digital processor Class A+ as follows:

"Best attainable sound for a component of its kind, almost without practical considerations; "the least musical compromise." A Class A system is one for which you don't have to make a leap of faith to believe that you're hearing the real thing. With Super Audio CD, DVD-Audio, and Hi-Rez PCM and DSD files now available, we have created a new Class, A+, for the best performance in those digital categories."

AHB2 - "Tightness, accuracy and punch"

"The most identifiable positive trait (there are many) of the AHB2, and that is low end control. Tightness, accuracy and punch."

"The AHB2 has power in spades, especially with two units running in mono mode."

"A single amp in stereo will suffice for most normal situations, and was in full control of all sonic responsibilities with every pair of loudspeakers we threw at it."

"The low end tightness and thrust is just where it should be, and pass though information is the name of the game."

"The sound of the amplifier is true to source and one that takes many queues from the production world of balance and monitoring."

"... will rock the house (or sooth the baby to sleep)."
