I wholly agree with Wayne's comments about the Zen vs. the Paramours.

I own both right now and I can tell you the Zen is a really good amp, but not as good as the Paramours and it is more tricky to match with a speaker system. Less output for one thing. 1.5 watts/ch. vs. 3 or so for the Paramours.

I think they only saving grace for the Zen in my system was the matching of it with the Bottlehead Foreplay preamp which has a lot of gain.

Keep what you have! Nothing wrong with a good 300B amp. And, yours is particularly beautiful.
