I’ve run a BAT Rex II preamp for the past 5 years with Mark Levinson Mono’s but recently got a great deal on a pair of REX II mono amps that I had to buy and try. Levinson’ s went up for sale the next day. Now with the full BAT REX system I’m enjoying music to a degree I didn’t think possible. The Rex II mono’s really transformed my listening experience and really improved on my prior amps in almost every way. My first thought was my goodness Mark Knopfler really sounds like he’s in the room singing now! I’m in a 20X24 room with dedicated AC so I’m not noticing any heat issues with the pair of these bad boys! Now I can only imagine how good the REX III’s are …
