You also may want to consider that those tubes match well with the Esoteric as source. I'm pretty sure that you don't want to extrapolate to other sources as the esoteric units I have heard have a definite "house sound".
I updated my impressions at Head-Fi. I really liked the Perfect Wave and I will have it in my system sometime early next year. That is saying a lot as it has no ability to utilize SACD/DSD and I still want to audition it. Resistance is Futile!
Actually it really was a useful exercise. There was some medical stuff going on in the adjacent room with a speaker and amplification. It was quite loud when the door to their room opened but was very quiet in the space outside and extremely quiet in our room. Bodes well for having a relatively quiet listening atmosphere at CanJam'10.
