My set is c.e.c. amp 3300/cd 3300 with epos els3. Listen it for a year, I found that I happy with its high but upper low (low note of sax and male's voice) is rather too thin. I've listened psb B25 with nad cd/int.amp, it's more impressive sound than my epos. Now, I plan to find bigger one replace epos. Between Focal chorus 706s and psb B25, which one is match to my c.e.c set, my room 10fts. X 10fts. and give me sweet and warm of upper bass. Thanks for all helps and comments.....
