I am wondering if anyone has any experience with TADs and fairly high powered tube amps like an ARC REF 150 or ARC REF 250's or even CJ ART amps. I am thinking of dedicating my CR-1's to an all vinyl, all tube setup and ARC is high on my list as well as a Manley Steelhead as the possible only preamp, eventually leading to a REF 10 + REF 250 combo. Any thoughts? Thanks!
