At first a faint hum on the audio outputs. Gradually increased until the hum was as at the same level as the music. Did all the usual trouble shooting stuff, new tubes & ect. Then total audio failure.
This unit was suppossed to be a giant killer so I was fooled into shelling out my money. No support at all from NOHR. The several times I contacted them, they were busy traveling the world. I guess cutomers do not count. 'JUST CASH THE CHECK' and run.
From this experience I wouldn't wish NOHR products on anyone

I was caught up in the hype. this was the worst $800 I've ever spent.
