Unfortunately due to where I live it's unlikely I'd be able to try out any gear before buying so I'm relying solely on reviews and like minded fellows to guide me. I took a punt on the Ifi zen one signature for playing files from my phone and it impressed me that much that it might just be good enough to ditch the arcam and use a transport to play discs. I've been quietly ripping most of my cds in as high a quality as possible so I think the disc player will be sidelined for long periods anyway. All of my mixes are extremely long so they are digital files only which was the reason for the zen purchase.
I'm pretty sure Peter at Deco audio said it would be around 200 pounds which includes postage, new transport, and labour, but that's before looking at it so the symptoms I described may have led him down the wrong path, or worse the parts are no longer available. I'll have to wait and see but there's no way you could buy a new transport let alone a dac for that amount of money. I have a rotel rcd 12 in another room which could be used as a transport to the zen dac but I'd rather that stayed where it was...
