Recommendation for vacuum tube CD-player
YEP- If you can find a Lector: Go for it! 
rolling output tubes
Vett93: YES- Sometimes a manual will include a range, rather than one specific setting for your bias adjustment(ie: Cary SLM-100= 150 to 175 mA). The upper limits of that range will yield a more dynamic presentation, and sometimes sibilance or gla... 
STANDBY on tube amps - what's your practice
It's very important to wait until your tubes' heaters warm up their cathodes, and create an electron cloud around them(in "standby") before applying plate voltage(B+, or operating voltage). Otherwise you'll wear out the tubes via "cathode strippin...

Jwong- Ever tried a Kimber Illuminations Orchid(minimum 1m) between your transport and CAL DAC? If not: I'll bet it would have you listening to your whole CD collection again(over and over). 
Less noise during intense listening sessions.
Turning the volume up to "realistic"(Radio Crap ruined that word for me) SPL levels is a great idea. Then again- 'Gorilla' makes some really strong duct tape that would solve the problem also! Timing would be of the essence if using that stategy t... 
Recommendation for vacuum tube CD-player
I have to agree with Newbee on the CAL equipment. I owned a Delta/Sigma then Alpha before my VK-D5 and was very happy at the time. Telefunken ECC803S's Didn't hurt my enjoyment a bit(everything, included a transport, would still be within your bud...

Find an older Balanced Audio Technology VK-D5(not the SE) and stuff it with six NOS Siemens CCa's(pre '68) or E188CC/7308's. You WON'T be gambling on chinese crapsmanship, and WILL be able to bathe in the sounds of accurate music reproduction. The... 
Which tubes to roll
That's a good link(thanks)!! His observations on chinese business ethics(there's a stretch) and manufacturing, mirror mine. BTW: If you like transparency, nice freq. extension in both directions, and liquid mids- The Winged 'C' 6550C's(latest iter... 
Which tubes to roll
The big difference between the tubes you mention is "power dissipation", or the maximum output that the tube is designed to produce at a certain plate voltage. ie: The average KT-88 will be designed to output about 35W, while the EL-34 is more bet... 
Which tubes to roll
For whatever power tubes you decide on: Upscale Audio's quality and customer service are hard to beat. Check out Kevin's procedures and offerings: (http://www.upscaleaudio.com/view_category.asp?cat=85) Both power and driver tubes have a major impa... 
Power Conditioning experience...
KUDOS on exploring, experimenting and experiencing one of the many realities that "can't work"/"make no sense"/"aren't scientific" in the realm of audio. I've had and appreciated(for the same reasons you mentioned) my Audio Magic Stealth XXX for a... 
Late-80's Philips CD Player Disc Errors
If you've had that player that long, and never cleaned the LASER: This wouldn't hurt- (http://cgi.ebay.com/NEW-Discwasher-RD1142-2-Brush-Wet-CD-DVD-Laser-Lens_W0QQitemZ120353745726QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item120353745726&_tr... 
Safe to replace fast blow fuse with slow?
Exactly as Herman stated! I've had correctly rated replacement Radio Crap fuses blow when there was nothing wrong too. Find some Buss or Littelfuse fuses at a real electronics store. 
How make my Ayre system "warmer"?
Mr T: You're right about the getter supports on the later CCa's being shiny metal. Also- They had the date code on a plate inside the tube. Mr N: The VK-D5 is also somewhat sensitive to the impedance it sees at it's output. It's bass will roll off... 
How make my Ayre system "warmer"?
I've got six NOS(pre- 1968) CCa's in my CDP(BAT VK-D5) and enjoy their presentation very much. Like you said, "It's also the gear into which the tubes are placed." My goal has always been to recreate(as much as possible) what I hear and feel in th...
