hi Victor,
we ahvee been trying to get a sense of how the 655se sound compared to your 55se and REX power but seems there has been close to very few user review.
there has been a demo unit just arriving where i am located but that unit is expected to take close to forever to break in (initial plug in does not sound like its nearing its full potential)
Would appreciate sonically how it appeals to you ... vs the 55SE / REX Power.
Simply very difficult to go the tube way as there would be more than 36 tubs if I were to use the REX PRE+POWER
So gonna give BAT SS a try ... my speakers are TANNOY WESTMINISTER SE, HARBETH M30 and Vandersteen Quattro...
insights appreciated ...
