I own a Transcendent Sound T8 stereo OTL, 25 watts/side into 8 ohms, paired with the Merlin VSM-M, and a pair of Zero autoformers, and never felt wanting for more power. Once you tried OTL, you will not go back to regular amps, tube or SS. Transcendent Sound just came out with a low power OTL kit, $1099 for a 15 watt stereo unit. Looks great and I am sure sounds great too. With the Zeros, you can get away with 15 watts.
Here is a link for info about the Zeros:

Also read about it on the ASOG bulletin board:http://www.condor-connection.org/asog/bbs/index.html
Good Luck
