interstage transformers vs. coupling capacitors

Got a question for all you dht/set types. Looking to purchase a 300b kit from either sun audio or audio note. The fundamental difference between these amps is the sun uses an interstage xformer while the audio note uses a coupling capacitor. The sun is also 2000 bucks more expensive. Does anyone care to compare/contrast these amp designs. My speakers are living voice avatar obx @94db and 6 ohms. Both amps are parallel single ended as I'm afraid one 300b at 9 watts would not be enough. I listen to many double bass concertos (Edgar Meyer). Also, to any of you 2a3 users out there, do you get enough badwidth on the lowther and similar type drivers to be satisfied with my music tastes listed above? One other thing, anyone care to compare a DRD (direct reactance drive), with the above configurations?

Sorry to sidetrack the thread here, but Twl inadvertantly brought up another point that i don't think that he was even aware that he was making !!! Since OTL designs would typically have a higher output impedance, wouldn't it be able to control / deliver more power to a woofer with a large impedance peak at resonance ? After all, we only run into problems in this area as SS designs put out less power at high impedances and transformer coupled tube designs are somewhat "hobbled" by the limited range of taps on the output. I wonder if Ralph at Atma or the folks at Tenor, etc... have ever played around with this theory and done testing ???

As to the original question, i would think that it would depend more on the design and the parts used than the actual method of coupling. I'm sure that either method can sound quite phenomenal with each having their own specific drawbacks. Sean
