thanks Antonio. i hope someday to audition and perhaps purchase the new REX 300 amp. i do not mind tubes in a preamp but going to take the easy road and go SS for the amp. Funny you replaced your Pass preamp with a BAT, as i did the same thing sort of. I replaced my Pass XP22 with a Coda 07x which i liked better, but the sound seemed a tad lifeless or anemic. Then i got The BAT and it improved on every parameter of sound. They make some really killer stuff and it is made in this country.
I heard a pair of those speakers at a neighbor's home of mine. really impressive for sure
