Awsmone, I haven't heard the CLX, but being a 90db/6ohm load it should be compatible with a wide range of amps. Running mono blocks requires suitable isolation and an extra high end power cable. What is your budget (including any cable/isolation purchases)? My experience with VA amps has been they seem to sound great paired with a wide variety of speakers due to their neutral tonal balance and natural, mellifluous sound. That said, although i'm a fan of Vitus, given you already own an Accuphase C-3800 pre i'd also consider the new Accuphase Instrumentation type amps including the A-70 & A-200 mono's (if your pockets are deep enough). I've read they are more neutral/transparent than earlier generation amps.
