I still highly recommend the ACME, especially if you can get it from a more reputable dealer (I got mine from China-hifi-Audio.com, and while it was a great deal, I'm a little wary of them:

The sound from the ACME 300b is definitely hi-fidelity, audiophile grade sound that's not analytical or cold, but refined, fast, open, has amazing instrumental separation, and sounds just slightly warm. Let's hope the WE300b will blow it away.
I can tell where the TJ Full Music stock sounds a bit slow, congested at times when there's a lot going on in the mids, but they are still fine musical tubes.
Anyone tried the Melz 1578 6sn7 tubes, by the way? I want to try those, as well as the Linlai 6sn7 tubes, too.
