Had my Amp repaired aproximately 1 year ago, was going to write soon after but family events meant I have been too busy until now.
I bought the amp from Ebay and it just sounded wrong, found it had blown an internal fuse which I replaced but it blew when John and he assured me it could be repaired, during this convesation we agreed it would be worth upgrading at the same time. Well all I can say is that has been fantastic since. Not long after Bought a A308cr CD did consider upgrading but during the convesation with John he mentioned Tri-vista 21 dac which he uses in modified form and swears by. I have now managed to get my hands on one. Really opens up the soundstage, so I will be contacting him soon to have this fettled. Lastly thanks john you are a genius.
