Here we go again; a DAC that leaves the reviewer gushing with praise juxtaposed with a so-so bench report from JA. Sometimes I see the dichotomy and suspect the reviewer is the culprit and sometimes I suspect the measurements simply fail to measure what is truly important. When it comes to listening impressions, I have faith in Art. It is obvious from the description of the design that some very solid engineering went into this product coupled with much attention to the all-important analogue output stage. The "problem" with reconciling listening impressions with measurements of DACs is that JA can't really measure the effectiveness/quality of the output stage. Put differently, a DAC can have the very best chips and good power supply regulation and measure just dandy and yet still leave the listener on edge. I am not in the biz and I am not an engineer. But that said, I (think I) know that with high-end DACs, you just have to listen. I would love to hear what folks who either own this DAC or who have auditioned this DAC think.

The gear Dudley praises almost never tests well. I enjoy his writing, but I read his reviews with a very skeptical eye. Some of the other reviewers seem to more frequently align with the measurements.

>>JA can't really measure the effectiveness/quality of the output stage

That is just not true. He measures pre-amps all the time. It is basicly the same thing.

Can JA comment on differences between the DP-777 and the NAD M51?

Both DACs are new and offer new technology to produce "analogue-like" sound, from what I gather.

Is the DP-777 that much better for 2.5X the price?

I've had two of these DAC's and both failed, so I'd say it's not worth the extra money. Also the SE upgrade keeps getting pushed out...I've been finding it hard to have faith in what their distributor says. Have had a nightmare experience with there Avatar as well on getting the repairs done. The units do sound good after a very long burn-in, but are definately prone to breaking down.
