I owned 2 Benchmark DACs. DAC 1 years ago and recently DAC 3 HGC. To me the benchmark sound is cool, dry, a more a matter of fact type sonic rendition of recorded music . I do agree though that the product is nicely built, rich in features and measures well. It’s priced accordingly. Just not my cup of tea. I was able to warm the DAC 3 sound with a good USB and power cables though but it didn’t do it for me. If you like it, good for you!
One other thing I will mention. When I called benchmark I spoke to a person pretty much right away. Their customer service is good. But whoever that was, I don’t remember now, recommended that I ditch my Pass Labs preamp and run the DAC 3 HGC direct to amp. I had already tried it by then and didn’t like the results. The claim was that my Pass preamp is noisy and degrades the sound quality. DAC 3 direct into amp resulted in flat, dry and forward presentation. It was significantly worse than having a preamp in the chain.
The volume control on DAC is definitely a useful feature if you’re in between preamps. But it’s not a replacement so no thanks….I like my preamp.
