Stax newbie here! I just picked up a Lambda Pro Signature with an SRD-7 pro-bias mod transformer box / energizer, and will have it next week. I searched through the thread but it's a bit of a monster at this point. I'm trying to figure out what amp I need to drive these.
First, and probably dumbest question: can I drive the transformer box with the speaker taps of my Denon receiver? I know it will sound terrible compared to a proper amp, but I'll definitely want to give these a listen as soon as they get here!
Otherwise I'm looking for the best bang-for-buck amp. I'm considering the Passlabs F5 (25W/channel class A) but that seems way overkill. I only need voltage swing, and not power, right? Why couldn't I use something op-amp based like the NwAvGuy O2 headphone amp modded for higher gain? Is there any default recommended pairing for the SRD-7 that I should consider?
Yep, any speaker amp will do. Connection instructions are on the back of the transformer box.
