Hi Mike,
I think it is a good product.
The HGC is a clever design that I found was within a whisker of my Icon 4 passive. The DAC section I thought was on a par with a Qutest, and took a nice step up when fed with an M-Scaler.
It would certainly be on my audition list.
Yes, it's absolutely a good product. Not only is the DAC section of the DAC2 very good, when I plugged it directly into my power amps (then Naim NAP135s), I immediately realized my NAC52 and Super-Cap were unnecessary. It sounded far better without them.
I was completely happy with it for years, then my friend indicated that it wasn't engaging enough for him. I thought he was being a nutter when he insisted he wanted to compare it to the Denafrips Pontus II. I was able to find one locally, and I compared it to the DAC2. I was surprised to discover that the Denafrips was more enjoyable and fun than the DAC2, and it's my current choice. However, both my friend and I still recognize that the DAC2 is still more accurate and detailed, even thought it's not as enjoyable.
My friend currently has the Chord Qutest himself. He brought it along when we did a head-to-head of all three DACs. The DAC2 was the clear detail winner. The Qutest (powered by an iFi SMPS) was slightly more enjoyable, but seemed a bit "mushy" with details. The Denafrips was clearly the winner in overall satisfaction, but my friend then decided he couldn't
settle for any of them. He wanted the detail of the Benchmark and the enjoyment of the Denafrips. We're currently watching for the Denafrips Terminator Plus and HoloAudio May KTE.
One more point on the Qutest: We swapped out the iFi SMPS for a linear supply that I made for him. That brought the Qutest almost in line with the Pontus II. (We also tried the Allo Shanti LPS, and it was a mere hair better than my LPS.)
As for the pre-amp section of the Benchmark DAC2, as I mentioned it was good enough to supplant the might Naim 52+Super. However, when I fed the Denafrips through its analog section, I found the overall presentation was very intense (over exuberant). Later I got a Benchmark HPA4 preamp, which solved the intensity problem.
So yes, the DAC2 (or DAC3) can get right of a bunch of boxes, but listeners may find it a bit too clinical.
