Response34, I had a push pull amp from McAlister Audio back in 2005 (believe it was called something 140, 70 watts/channel). Problem with his amp was very poor build quality, although the sound was good. The output transformers had laminations missing that was filled in with small pieces of metal and was caked with this greenish stuff that looked like it was oxidized from years of use. The soldering job was by far the worst I have ever seen, looked like a 10 year old had at it. Speaker binding posts were completely loose when it came to me. Fortunately it cost only around $1600 at the time. I was not the first who had issues with build quality of his amps. I sold it after less than 1 year of use for about $700, but it broke down less than a week after sale. He is now charging close to $9000 for his OTL amp. The outside cosmetics has been upgraded, but I hope he has vastly improved his build quality and reliability for this amount of money. He can take a lesson from the build quality and reliability of Atma-Sphere amps. BTW I have no financial or personal affiliation with Atma-Sphere.
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?
