Silent Source high current version is a pretty good match, at least in my system. Cheers,
I've noticed the a number of owners use TG Audio SLVR's. They pop up on agon periodically. I just picked up a pair and I'm very happy with them on my MA-1 Silver Editions. Please note that along with them, I installed a dedicated 20 amp line which I consider one of the hugest improvements to the dynamics from these amps.
