Die-Hard Proceed Owners...

I think I'm about to join the ranks of Proceed owners, having been offered an AVP (not AVP2)and AMP5 ex dem in UK. This kit is not common over here. I know that there is no future support, although I thought I might be able to get an AVP2 upgrade. The sound quality just seems better than anything else I've tried, especially on music. I've listened to the Arcam, TAG, Bryston, Naim,and none come close (OK the Bryston comes close, but costs £3k more in Uk v the ex-dem Proceed price.
I am a bit worried about bugs, however, as I have been advised that the AVP can buzz and click on DTS.
Any experience of this, or indeed of the brand.

As I don't use a subwoofer the crossover changes are less important to me, but I would love to have access to PrologicII. Is this a major improvement on standard Prologic.
Unfortunately, I cannot find any AVP2 or upgrade kits in UK, and would prefer not to buy a US model with the resultant need for voltage change.
Certainly I remain enthralled with the sound quality from the standard AVP, both on film TV and music.

One question, on the demo unit I am trialling, all the lights on the buttons came on together suddenly last night. Whilst they went off again, I have now lost the first four digits of the display, which is a bit irritating/worrying. Has anyone experienced this?
Secondly, I have linked the AVP to the AMP5 using the PHAST ports, but this doesn't seem to result in the AVP controlling the AMP as I expected. Standby on the remote still only affects the AVP. Am I doing something wrong?
