I won't comment on headphones Ian as have in other threads and am still forming long term opinions.

On the source side, I feed the prime/ps via USB from the squeezebox touch EDO plugin, the PS making a significant difference to the quality of the USB feed, which leaves me the coax out into my main system.

Roon integration into Squeezeboxes would now get you MQA also I understand, however as I don't subscribe to Roon at this point I cannot comment on this, and remain frustrated on MQA given no LMS / TIdal plugin solution as yet.

I know squeezeboxes are old hat to many, but still a great piece of very versatile kit that looks the part in touch format, particularly sat on top of the prime/ps stack...
