I sold a Rega Apollo CD deck on ebay for 220 pounds.
The buyer has now told me that the coax digital output doesn't work and this was the source they wanted to use with their DAC. The other outputs work fine.
I apologised and explained that I had never used either of the digital outputs and wasn't aware of the problem. I offered them to return the cd player and get a full refund.
Their response was to suggest contacting Rega for repair costs, I said I thought that they would be uneconomic on a s/h player.
They have now said that I friend has suggest they use the digital optical output but need a decent interconnect for 50 quid plus postage. This is for 220 pound player!
I have rejected this suggestion and have again offered a refund.
I am being unreasonable?
