This has been a very tough decision.

The TADAC is simply a marvelous sounding piece. It also has Paul's "tubiness" knob which allows you to change up the harmonics to your liking. A pretty nifty feature. I also had Paul send me a pair of his favorite Chinese tubes to do an A/B with the stock tubes. I actually liked the pair Paul sent me. However your listening preferences might vary. The unit is rated 9/10 & comes with both sets of tubes & PC. $675 incl. insured S&H to CONUS.
