To expand on my point above. I don't put much stock in reviews or in-depth impressions. IMO the vast majority of them take a lot of words to say very little. And I mean that about all audio reviews, not just those on this site. HF has a few decent reviewers. The rest, not so much--myself included. However, I think loaner programs enrich the discussion here, not because more people can write long reviews. Rather, I think loaner programs such as the Ref 7 that is the subject of this thread deepen the knowledge base and provide more data points.
My main reason for participating in this program was due to the fact that I had been an outspoken critic of what I perceived to be shilling for audio-gd. I figured I should at least hear one of their DACs if I was going to be critical. I heard the Ref 7; it did not knock my socks off. It sounded fine. I don't have much to say about it other than that. However, if people have specific questions, I am happy to try to answer them. I think this site works much better as a discussion than a bunch of mediocre reviews. In my experience, ears I trust on this site saying "I like it" or "meh" tend to be much better indicators than someone I don't know who writes a treatise (I think in particular about some of the professional Bryston reviews, which left me thinking WTF after my time with that DAC).
As with all things, reasonable minds can differ on this stuff. I just find this place more informative and interesting when it doesn't try to sound like the audio rags. There are also plenty of impressions in the main Ref 7 thread. Enough to keep anyone occupied for hours.
