Advice on popping noise from Audio Aero Prestige

I recently upgraded this player to 'signature edition' (cryo tubes, exotic caps, better damping). Sounds brilliant and is an improvement over standard unit. Upgrade took place at factory in France.

Popping noises (esp on left channel) now occurs whenever volume is changed, pressing stop, or choosing next/previous track. Also, player gets confused on repeat play (at end of cd/sacd it either stops or goes into scan mode). When system is idle, a buzzing sound comes through left channel. However, when playing music none of these noises occur.

Prior to upgrade, no such problems happened. My dealer suggests that I should burn-in the player for longer in the hope that popping and buzzing significantly reduces. I'm not entirely convinced this will work and seek other suggestions/solutions. Also, is it safe to continue using this player?

Thanks in advance.

Cics,

Let us know the outcome in this thread as I have just purchased the Audio Aero Prestige CD/SACD player.
I think that most people here feel and know your frustration. Really press the issue of not paying for shipping anywhere and see if you can get a "loaner" from your dealer. There should be some "perks" for purchasing a $13 000 US MSRP player!

Cics,

Do you have the AA direct to your 33H amps? What amps did the dealer use and did he hook the AA up directly as well?

Thank you for keeping us up to date. I was thinking along the lines of a small DC spike when making input/volume changes. This would be noticeable with amps that do not block incoming DC.
With the buzzing, the culprit could be one (or both) of the new cryo treated tubes. Can your dealer re-solder in new tubes to try that out?

Cics,

As it turns out I also have the "pop" sounding noise when changing the volume, stopping or changing next/previous track. For me, it really is very small in loudness and not bothersome. I will, however, keep my ears open and post in this thread if anything changes.
I have the Prestige hooked directly to a Bass Augmentation Module (part of the Merlin VSM-MX speaker system) then directly to a pair of Joule Electra VZN-100 OTL monoblocks.
I do not have any buzzing noise while the player is idle.
Like you, there was no damage at all on the shipping box and it was packed well!
After I have let this 2 channel SACD/preamp player settle in my system for a while longer, I will post a review.
