Do you leave CD players with tube outputs on?

I've been leaving mine on for many years. My tubes tend to last years, not months, too. That makes sense to me, since they are relatively low output.

I have left my player on for 72+ hours and do hear improvements in sound stage both width and depth, and a little more detail. The CD player runs quite warm to the touch -- Is heat a concern??

Hchilcoat -- It's hard to say. I'm not sure which Ayon player you have, but if it is the CD3, with 4 x 6H30 and 1 x 6AX5 tubes, and if it does not have a low-power standby mode, its power consumption is well above average for a CDP, and would easily account for the heat you noted. That would be a bit less true of the CD1 and CD2.

I don't have complete specs on those tubes, but it looks like the filaments alone draw around 5 watts for each of the 6H30's, and around 8 watts for the 6AX5. Factoring in plate dissipations, and power for other circuitry, I suspect that the 50W consumption specified in their datasheet is a bit understated.

Whether or not that would pose a reliability problem in the long-term would be dependent on how well the thermal aspects of the design handle the heat. The 25kg (about 55 pound) total weight of the two chassis, and the fact that the unit is split into two chassis, is suggestive of good design in that respect.

But beyond that I would say that your guess is as good as anyone's, unless the manufacturer can offer specific credible advice.

THanks, Al. I have the CD-1. The distributor states that the manufacturer recommends turning off with each use.
