If anyone knows if it would be better if an OTL tube amp were designed for 3 ohms vs 4 for a Maggie 3.6/3.7 let us know.
Other than that, they seem very suited for what planar speakers do, especially in terms of the fact that planar speakers are so transparent, and then the OTL aspect maintains that through the system.
Another question - because where money is an issue in my systems, I wonder what people would think about matching a relatively cheap ClassD amp, like the Rotel 500 watt ICE in an active bi-amp setting.
I've heard that with active bi-amping amp-matching is important. Remember that the 3.6/3.7s cross over at 200 - 250 Hz, so we are talking low frequencies where quality matters less because of the physics.
Given the high cost of OTL, this would be an interesting option:
24/96 source
Good DAC and Pre
Bryston X-over
Rotel RB-1572 (although I'd love to use the ICE1000 vs 500, they stopped making theirs, I'll poke around for another 1000 module)
Atmasphere MA1 or VZN-160 or The Beast
Maggie 3.6
The OTL amp still consists of most of the cost of all of this, unless one gets The Beast and builds it themselves.
Note that going active bi-amp makes the high-frequency amp at least double in effective power by isolating the range of frequencies it has to deal with at once.
I have to look into The Beast more. The other OTL amps are out of my range at the power required to drive Maggies, for more efficient speakers I'd be there in seconds.
Has anyone heard it recently? Does it really sound as good (or nearly as good, I'm sure it isn't as good) as any of the other OTLs, or is it much more limited in quality? Is it compromised enough that its doesn't that the OTL sound anymore?
