Though at first glance it might seem counter-intuitive, but, for a load like the Thiels you might be better off with a bigger Classe' than two bridged smaller ones.
Can you get good sound bridging 2 Classe CA-200s
I have had on-going issues with my Classe CA-200 amplifier's mosfet fuses blowing out driving my Thiel CS2.3s. The sound is excellent, however, after 40 to 60 minutes the amplifier gets hot and the fuses blow. (I do play music loud). One reasonably economical solution would be to find another used CA-200 and bridge the amplifers to double the power. Will this work? Will the sound be as good? Has anyone tried this. Thanks!
