Any Steven Huntely clones???

I communicated with the Great Northern Sound in the past about upgrade path for my stock Wadia 860x. Now that the unit locked up on me and I am ready for the mods I find out that Steven no longer operates his company. Are there any other reliable folks stateside who can do this. I know Henry Tang at Musical Coherence in UK does some of this. Thanks
Thought I saw a few names that Steve recommended when he quit the biz. Was it on his site? Can't remember.
I read some recomendations for Henry Tang at Musical Coherence Ltd in UK but shipping an 860x to UK would likely be a real joy.
