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.

Thank you for your prompt responses. The player is getting worse. I'll be sending it back for repairs - its still under warranty.

Another 3 weeks of waiting in frustration...

Johnny - Fortunately, I haven't paid for the upgrade yet but yes this should never happen in high-end audio. Its just sloppy qa or workmanship on the part of the factory. It feels like a backyard/garage operation!

Cics,

Just as a follow up. The unit may have been damaged in transit. I have heard of PC boards being cracked during shipping. The Manufacturer will be able to investigate the unit and evaluate the problem. Point being the fault may not lie at the hands of Audio Aero. The problem may be the result of shipping damage!!

Why would anyone cryo tubes to begin with? It seem stupid.

Transport damage is a possibility however on receiving the unit, I could not see any damage to the box. No stress marks, kinks, etc. that would suggest physical abuse. But transportation could definitely be a factor and I may be incorrectly faulting Audio Aero.

Rwwear - quote from Audio Aero on cryo tubes: "2 cryo'd 6021W high precision matched Philips tubes (tube is frozen to stabilize the molecular structure from the tube and to eliminate moisture)".
