DAC1 - "A clean, lean digitizing machine"
John Watkinson, author of "The Art of Digital Audio" wrote:
"If the use of an exotic cable makes a DAC sound better, then the DAC is not performing adequately and should be repaired or redesigned. If the goal is actually to achieve high quality, rather than just claim it, then this is one of the fundamental tests a designer should use."
"As can be seen (from the graph above) the DAC1 easily operates with total freedom from jitter at the end of a 1000′ length of CAT5e data cable."
"Whoever heard of a DAC operating without jitter induced sidebands over 1000′ feet of garden variety data cable? Now that’s a properly engineered device!"
"Benchmark. That’s a loaded name for a component manufacturer. It brings to mind thoughts not only of quality build and performance but, for those philosophically inclined, also epistemological questions pertaining to the nature of high-end audio."
"Certainly one means of establishing a benchmark is through testing. Speaking of specifications, never have I seen such a cascade of specifications attached to a DAC as with the DAC1."
"Benchmark is willing to trot out every iota of information to assuage the objectively minded audiophile."
"The DAC1 was created with three target users in mind: the professional studio, home use by audio professionals, and audiophiles. Indeed, the DAC1 has been well received by studios and has made inroads into the audiophile community. It is feature-laden and smartly laid out."

"I conducted an informal online interview with John Siau, Director of Engineering at Benchmark Media."
According to John Siau:
“UltraLock is a clock isolation system. The incoming digital audio contains an embedded data clock that often contains high levels of jitter. UltraLock creates an impenetrable wall of separation between the high-jitter embedded data clock and a pristine fixed–frequency D/A conversion clock…Jitter from the transport cannot reach the D/A converter.”
"I’ve not heard any dac in a player or outboard that has coughed up as much miniscule movements in the music as the DAC1."
"It does what it claims; even a “low life” CDP’ can sound great with it! You can take a $100 (at least in my experience with the NAD player) cdp, hook it up to the DAC1 and get horribly good performance!"
"It’s more than a DAC, it’s a pretty doggone good preamp too!"
"It presents hyper-nuanced, super clean sound."
"The Benchmark is a clean, lean digitizing machine. It does set the standard at its price point for pure, unadulterated digital signals coming to your nearest amp(s)."
"If you’re after the most measurably perfect CD sound and endless detail, put it on your own test bench – your audio rack."

"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."
-10 Audio, Perfect 10 Award
Alpha-Audio.net tested 10 DACs side-by-side. Only one received the "Alpha-Audio Approved" award. That DAC was the Benchmark DAC3.
"Are you looking for the best DAC (d/a converter) in the price range from 1500 euro to 2500 euro? That’s great! Because we’ve put ten beauties side by side. And we tested it live on camera for you."
"It was incredibly instructive to put so many converters side by side. We clearly hear differences - and the viewers could as well."
"One of the models we all agreed on is the benchmark DAC3. This is a delicious musical product. Virtually no coloring, nice stereo image and plenty of inputs."
DAC3 - Alpha-Audio Approved!
"Prior to reviewing these Benchmark components, I had heard the company’s products powering some of my favorite-sounding rooms at several audio shows. Based on what I’d heard at these shows, I was eager to hear how this equipment could perform in my own listening room."
"Listening to the Benchmark gear in my own room, I felt an immediate and gratifying emotional connection to the music I was hearing."
"The LA4 and AHB2 tear down so many of the usual walls that come between the listener and the music."
"If you value transparency and accuracy, the LA4 and AHB2 will perform beyond your highest expectations."
