Update:
Have been running the Brio-R since last Friday. Sounds good, but seems a little soft. My current cables are Mogami. I swapped them out for a pair of Kimber 4tc (blue) I had stored away. The sound immediately opened up. However, I still do not have the punch I want. Of all the british integrateds I've owned (Creek 4330SE, 5350SE, Exposure 2010s, Naim Nait 5i, Roksan Kandy MKIII and now the Brio-R) the Creeks have had the bottom end punch. But, with using the british gear with the vandersteens, I've always had to use other cable other than the Mogamis. I recall when I had a Creek 4330SE with a Naim CD3.5, I was using DH Labs Q10 with Air Matrix interconnects. Again, the Mogamis were too soft with that combo. The mogamis are supposed to be a very neutral cable, and I wonder if they are telling me the gear is wrong when they cannot be used?
My last power source before trying the Brio-r was an vintage Kenwood KR-5030. It was 60wpc, but it was one of those models that had the low end punch. It sounded good and I was using the Mogamis.
Curious now about low end punch in the Yammy A-S series? I'm sure NAD has the low end punch. I see another person had mentioned the Acurus DIA-100. Although, with that I would have to get a phono preamp, which isn't a big deal.
