I have monoblock Nuforce Reference 9 Special Edition Amos, which Bob Smh of mytdss upgraded for me a few years ago.I'm having a problem with the amps..I tried going to the mytdss website, but it no longer exists. Hopefully, he didn't pass away.Does anyone have any info as to what is going and where I can have my amps repaired? I'm feeling very sick about my amps needing repair work and whether I can have them repaire
