This is a late post but may help anyone with the same question. I have the CD5s and certainly agree it is spectacular! It opens from the bottom with a special long Allen Wrench that reaches through holes in bottom. Call USA Tube Audio and they can send you a short video of opening the unit. Bets tubes to Replace the 6H30's are Russian Reflectors NOS from the mid 70's to 1980, they will take sounds to new level. The power supply tubes are good to go as the stock ones. These are all 10,000 hour tubes but I would consider replacing them when they are about 5 years old depending on use. Hope this helps!
Ayon CD5S Tube Replacement
I I have recently purchased the above in excellent condition and very happy with the outstanding performance.
The improvement over all my previous CD players is amazing with drastic improvements to resolution, imaging and superb mid/range with another octave of bass!
This player allows streaming via USB and the results are equally impressive highlighting the performance of an exceptional DAC.
The CD5s came boxed and with the Ayon User Manual - that did not provide any useful information regarding tube replacement. I expect the 6x4 rectifier tubes may need to be refreshed - as I notice after turn on the display pulses for a while but becomes stable after about 15 minutes. I am not sure how many hours this machine has done so I would prefer to simply change the rectifiers_
Can anyone explain how to remove the top plate of the CD5s to enable tubes to be replaced as this is NOT obvious and secondly which brand of tubes work best for the power supply and signal path (6h30)?
