Best repair people for my Threshold 400a?

Hi

When I do a search via Bing or Google for a Threshold 400A the following link for a tech comes up that I haven't heard of when it came to repairing Threshold amps.

Ken Ealey Audio

I always thought Jon Soderberg at Vintage Amp Repair was the main man when it came to repairing Threshold amps.

Has anyone had their Threshold amps or any other amps repaired by Ken Ealey? What was his work like?

He goes into a lot of detail as to what he offers.

Thanks JD

Thanks for the help everyone. Since I'm in the US I'll get in contact with Jon Soderberg ASAP. JD
