This morning, they suggested that I ship the amp back to them.They are bad to deal with, I’m in Australia and had an older CDP in for repair, as the main board was double sided and was hard to fault find, so I needed a service manual or at least circuit diagram.
The answer was a flat NO even if I paid for it.
They wanted it shipped back to the US for them to fix at great cost, shipping plus their high labour rates would have been 2 to 3 x the worth of the unit. The customer put it in the recycle bin.
No reco from me.
Cheers George
