OTL amps

Very speaker dependant but a magical midrange when you get it right. I like the Atmasphere products.

I have Kharma CE_1.0's how will they work with them.

I have Joule Electra OTL monoblocks, and I agree with Glide 3 that the performance is somewhat speaker dependent but on suitable speakers, the performance is stunning. I am unfamiliar with the Kharma speakers, but basically, OTLs work best on speakers with higher and relatively stable input impedance loads (definitely above 4 ohms and preferably in the 8 ohm and above range). As for specifics about the sound? My experience is that the OTLs have an extra special "purity" and "clean-ness" that on well-recorded material really makes one appreciate how beautiful music can be. Can other amps of different but well-executed design do as well? They're so many good ones out there that the answer probably has to be "yes." I've just not heard them, so for now, it's the extraordinary purity of OTLs that makes the difference to me.

Be careful with that combo, the Kharmas are basically a 6 ohm load, which gets to be borderline with an OTL. I have the CE 2.1s on order Merle, why not go with Lamm? The Lamm M1.1s (at an appropriate discount of course) are only slightly more expensive than the Joule OTLs or the bigger Atma-Sphere OTLs. I have the Lamm L1 preamp and it is so amazing, I implicitly trust anything Vladimir designs at this point. The Lamm/Kharma combo is a particularly synergistic one.

I have Transcendent Sound Stereo OTL driving my Merlin VSM-Millennium and love the combination. The Transcendent monos (80 watts/side) can drive down to 4 ohms successfully. I prefer them over Atma-sphere as they don't run as hot and are more dynamic. As far as price goes, they are reasonable as they are sold factory direct (www.transcendentsound.com) with a two-week trial period.
