Hi Guido,
The BC Ref 1000 Mk2's and JR kit have been in my home system recently, though not side by side and my notoriously fickle audio memory [all 2000 milliseconds of it] was therefore aided by written notes of observations of reproduction of reference music. In a nutshell i did find the BC more refined than the JR mono's. Both amps have remarkably quick leading edges to notes but i found the BC better at fully developing the harmonic tail [decay, sustain and ultimate release] of notes. IMHO both power amps benefit from tube pre-amplification - though that is admittedly a matter of personal taste. I can't comment on the Capri + BC overpass of the bypass :-) but if the net result sounded anything like the JRDG 500 continuum then i'd be worried that the solution was so wrapped up in the uber reality high definition means of musical delivery that it forgot the meaning of the message.
