Hello all - thought I'd chime in on this epic thread as a new Brio-R owner (who consulted this thread a few times in the decision to acquire said Brio). I recently decided to trade the SX-850 in my avatar for the Brio-R (guess I need to change my avatar...). It was a difficult decision - I'd had that 850 restored and was really attached to it, aesthetically loved it dearly. But it continued to have issues even after the restore, and I was using it in an office system where it was just a beast spacewise. When I got the offer to trade it for the Brio-R, after reading all of the Brio's many rave reviews, I decided it was time to move on. I was admittedly very anxious that I was making a decision I would regret, felt like I might be trading a unit with great soul for a disposable and soulless sliver of black plastic modernity.
All of that anxiety was dispelled, literally, with my first listen to the Brio. Sonny Rollins' The Bridge on vinyl. 30 seconds into "without a song" and I was aware that I had moved into a different arena of hi-fi with this piece. The detail and spatial presentation is stunning, even in a space as small and awkward as my office. I'm also just amazed by the phono stage - unbelievably quiet. I get absolute silence at any volume with phono selected. It's making my workingman's sl-1600 sound like a pretty serious deck.
As has been often noted before the cramped rear panel is annoying and mine runs pretty warm driving KLH 17's. I have maybe 25 hours on it now and though I'm aware of a forward presentation, I can't say it's bothering me in any way, and I am usually very sensitive to high-end sizzle. Could be the fact that I am primarily playing vinyl and that the decidedly rolled-off East Coast sound of the 17's is a good match. But... well look if it needs as much break-in as people here have said then I'm in for a treat, because I think it sounds great now.
Bottom line for me - though I guess it depends on where you're coming from, but it's hard for me to imagine being disappointed with this unit for the price. And if you're swapping this in for a massive 70's receiver, well, let me tell you... opens up a lot of shelf space...
