Glad to see someone going down this road. I ran 3.6's with my VZN 160's. I have very fond memories of it. I had the OTL's driving them full range and even bi-amped them with various amps for just the bass panel, including the H2O ice audio class d amp. My recollection is that the biamping of the 3.6's in this manner was overkill for that speaker. I much preferred running the 3.6 at full range and augmenting that set up with a sub. As a Maggie enthusiast, I also augmented the 3.6 with Tympani bass panels (single pair and double)driven with the H2O. That was a good system for a while. I always ran the OTL's with the zeros. I don't think I ever turned the volume past 12 o'clock. OTL and ribbons are a glorious sound. But for the lack of imaging, I'd still have that system.
OTL Tube Amp for Maggie 3.6?
I've heard OTL needs an impedance curve that never drops below 4, and flat is better. I think Magnepan 3.6s drop here and there below 4, and certainly aren't flat.
So, would OTL not work?
I think from what I've read it wouldn't matter, but would getting one with lots of power make a difference (i.e., Transcendent The Beast) or is that irrelevant?
