Not much at all for the mods. The first thing Steve did was simply to change out the Op Amp, which only takes a few minutes and is compatable - which by itself, changed the sound dramatically. Then when I asked if anything else would improve the sound more, Steve recommended improving the power caps which serve the Op Amp. He installed higher quality and higher capacity capacitors.
The total time ivolved was around an hour, so I got the job done for his base bench fee plus parts.
The changes are easily reversible, but you won't want to do that. I have never heard such an airy 3D soundstage, and detailed yet liquid highs without a trace of harshness. Didn't think it was possible. The sound is also true to life and immediate yet rich at the same time.
I recommend that you call Steve up if interested. Simply yahoo Steve Sank, Talking Dog Transducer Co, Tucson if interested.
