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."

"Since the HPA4 arrived, I have rediscovered so many of my favorite works all over again with improved detail retrieval dynamics and transparency that it’s hard to pull myself away!"
"It drove my power hungry Abyss Phi TC headphones with complete authority, but it was still dead silent and nimble enough to amplify my easy to drive Focal Utopia headphones."
"Rarely have I come across such a wonderfully revealing amplifier that can drive many different types of headphones so darn well! The solid build construction and various controls make the $2,995 price tag seem a bit low based on the other headphone amplifiers in this market space."- Peter Pialis, Headphone.guru
"Benchmark Media Systems’ LA4 preamplifier presented an utterly realistic reproduction of what was contained on each recording I played through it -- and weak recordings stood out more than usual. The LA4’s clean, analytical abilities are unmatched by any similarly priced preamplifier I know of. The LA4’s touchscreen brings it up to date with current user interfaces, and permits functions, such as balance control and muting at the device."
"If you want a preamp that editorializes, look elsewhere."
"If, like me, you value a high-resolution, totally neutral musical performance, add a Benchmark LA4 to your system, particularly if you already own a Benchmark DAC."

"You’ll have a tough time finding a cleaner, quieter, more transparent line amplifier and headphone amplifier anywhere, at any price. I found it to be a new reference. Once I heard it, I could not live without it, so I purchased the review sample. The HPA4 deserves my highest recommendation."
"The HPA4 is the latest product from Benchmark Media Systems, an upstate New York audio manufacturer. Benchmark calls it a headphone amplifier, but it’s really two products in one, combining the LA4 Line Amplifier introduced in 2018, with a headphone amplifier. It is also based on the same THX Achromatic Audio Amplifier technology used in Benchmark’s acclaimed AHB2 power amplifier."
