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?

Even MORE important than sensitivity is the phase angle of the load.
That is to say....how capactive or inductive the speaker is.

Find the Stereophile test of the speaker. The test is in their archives and will have an impedance / phase graph against frequency.
Read the recommendation of stereophile's testers and take in account your experience and needs.
Now, I don't know specifically about OTL, but normal, transformer'd tube amps do not like capactive loads....even if the impedance were fairly flat.
