No Bi-Amp but tubes for Maggies -- can it be done?

I think(have never tried them myself on maggies) the atma-sphere's would sound great, the only problem I have is that they are OTL's. Which means nothing is between your output tubes and your speaker, and in the maggies case may be dangerous if you did any work to them(i.e. if the fuses aren't in place, I wouldn't even think of trying an otl). Don't get me wrong I love otl amps, and ribbon tweeters are relatively cheap for magnepans, but your much more likely to have problems with this set up and it would get tiresome quickly- IMO. But if you have fuses there is much less at risk and I am sure the sound is first rate.

I HAVE tried the MA 1 Mk II.2 on Maggies and there are zero problems. True the Magneplanars do not present an ideal load for an OTL but there is not a hint of instability. The Atma-sphere is NOT a ribbon tweeter eater.

Greenman- Your missing what I said, the magnepan uses a ribbon tweeter- I sure hope your amp doesn't have a tweeter in it! I was merely pointing out that you are more likely to have a tube failure effect a ribbon(on the speaker) with an OTL then with any other type of amp. Some will never have a problem with output tubes but with a power hungry speaker the tubes are working over time. The load isn't a big deal its a stable 4 ohm load, but the maggies are still an 85dB with TONS of driver area that needs gobs of power(both watts and current) to make it happen. And as I said if you have not modified your speakers then this is not an issue but then again your not even hearing 30% of what your speakers are capable of with out modification. Does that clear up your confusion?

Tireguy, no confusion on my part. You're talking theory and I'm talking practice with unmodified Maggies. Try not to be so patronizing, especially when you lack first hand experience. I don't need a lecture on either Maggies or OTLs. I'm actually a fairly bright guy with 30 years of high audio experience.

If that's the case why did you think that I said your amps had ribbon tweeters in them? Just calling them like I see them. And I do have experience with OTL and maggies just not the atma-sphere's so try and relax this hobby is suppose to be fun ;)
