I posted this elsewhere:
Kim did subpar work on a cart for me, and when I sent a photo showing an obviously crooked cantilever he responded with a ridiculous word salad instead of just saying what he should have said" "I'm sorry. Send it back and I'll make it right." After a bit of back and forth I decided to send it elsewhere because I was getting a real strong vibe that he was going to spit into my soup, if you know what I mean.
Based on everything I've read about Kim, on Audiogon and elsewhere, your odds of getting a job well done are pretty good, but there's also a chance you'll get hosed.
The work I've had done by Soundsmith, VAS and Joseph Long was all done correctly the first time.
