Had a wee listen, but I'll reserve judgment till it's had a few days to settle in.
First impressions was that it sounded a lot fuller with more detail than the VRDS-20 but only because it is a lot louder at the same volume setting, once I adjusted the BP25 the units are quite similar in many ways, which is a good thing.
The VRDS-20 is 3.6mv (7.2) through the balanced so the BCD-1 must be around 4mv + or something.
I’ll have to get use to that draw though, the VRDS-20 is silky smooth and polite, the BCD-1 is more like, “come onnn, put another CD in there, clunk, that’s better, now sit down and listen.”
