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!

There shouldn't be any moisture in a tube since it is in a vacuum. If there is it can't get out even if you freeze it or heat it.

David - Will definitely inform on how this plays out. This player takes a long 2-3 months of burn-in and unfortunately my dealer can only loan me a new one. The difference is not subtle as you will find out. When its in the 'zone', its just brilliant.

Rwwear - Your logic cannot be faultered. AA provides this as part of the 'signature edition' kit. (You also get a 'signature edition' decal which is attached to the transport tray face). My understanding of this treatment is that its temporary and benefits wear off over time.

Took the player to my dealer and tested it in his system. No pops or buzzing whatsoever!

The thinking now is that it could be a grouding issue - I am puzzled as nothing has changed in the system except for it being powered down completely for 2 weeks.

Does this make any sense?

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?
