Can OTL's drive ribbons well?


Seeking comment on ability of OTL's to drive mids/highs ribbons, specifically on Genesis II.5/300/350.Prefer to consider without zero autoformers as they have a reputation of bleaching sound(?).Can they do it without losing their special sonic ability of speed and organic liquidity? I guess I am really asking this question of the more affordable OTL's, ie.Transcendant, Atmasphere MA1 etc. If OTL's cant do it, which tubes can provide fast organic liquidity with dynamics at around $4000 and hopefully much less(new or used)-- again specifically driving ribbon mids and highs?

Finally does anyone use Cello duet 350 to drive ribbons?If so how do vocals sound?
Thanks and appreciate your comments

I have driven my Magnepan 3.6's (which have a vertical ribbon driver) from the Atmasphere MA-1's and the MA-2's, both with and without the auto-transformer. To make a long story short, the sound is spectacular with the auto-transformer. It is detailed, liquid and without any grain or harshness. It is a superb match and without introducing any anomalities. Without the auto-transformer the sound is still excellent but, the response is a bit uneven. There is a little bloat in the midrange and, perhaps a slight downshift in the extreme treble. This is more true with the MA-1 than MA-2. No doubt this is due to the rather significant internal impedance of the amplifier starting to affect the overall speaker crossover impedance.
Genesis ribbons are fairly stable 4 ohm loads with a bit of trouble in the 85 to 200 Hz area that is taken care of by the crossover. OTL's might not be the best choice because they are designed for 8 to 16 ohms, usually. Some of the bigger Atma-spheres have no problem with 4 ohms. One thing to consider on the OTL's is the cost of retubing every few years. There are tube amps, like Manley that are designed for low ohm loads.

I have heard people swear by both SS and tube amps for the Gennies but they all say they like lots of power. Not sure if speed is an issue but tubes usually have a slew rate much slower than SS. Edge and Monarchy make some of the fastest nowadays.

I have not used OTLs but the best Triode operated amps
from VTLs or Antique SoundLabs (try Hurricanes) should do these well. I own the QRS and Genesis II.1s and the ribbons are driven phenomenally well, beautiful, is the word with
VTL 240s which use 807 tubes in triode configuration for
arround 100 watts per side.
