David Yee Tube amps?

does anyone have any info about David Yee amps good or bad. I'm considering buying one but want to hear from some A-goners with some experience.
Hi, any feedback on the David Yee amps? I am pondering on one as well. Your insights very much appreciated.
I know David Yee personally, He has built a headphone amp, a guitar amp, and a small el 84 amp for me. For the price, I can't honestly think of anything, especially custom made, that can touch it.
He built himself a higher end el84 amp that compares favorable to my Almarro a205mkII, FWIW.
Cons, the build quality and appearance ain't exactly stunning, cheap pots, jacks, etc... but for the price, If you want to get into tubes, it's a no brainer. period
any body know anything about his tube buffer
David was my previous landlord in Vancouver. I ended up buying a pre-amp, amp and tube buffer from him. $400 each.
He gave me five amps to try out at my apartment. I picked the one I liked best and David agreed.
The sound is magnificant.
You don't have money spent on frills such as cases
Max sound for min dollars. One volume knob went bad after three years and he replaced it no charge while I waited!. The tube buffer made a tremendous improvement. Impedence matching was the reason given.
I have never had any problems. Seems to be a straightforward Hong Kong guy (genius?) that speaks English poorly.
email me if you want more details. I see him slagged here and I just want to mention that all my interactions with him have been good and I am still a repeat customer.
