Which Room is Best Between These Two
My room measured just outside of the bolt area, but it was because of an 8' ceiling. I have an 8' ceiling but it's a little taller on one side, which can be better than a 9' ceiling because it isn't parallel to the floor. 
Why so many tubes?
The only problem I have with all this detail is you don't hear it like that in a live environment, maybe that's why people like set amps. 
Amperex 6DJ8 tube construction
This is just a guess, but a splatter shield may be to prevent secondary emissions. 
16 bit vs 24 bit vs 35 bit vs 36 bit vs 64 bit DAC sampling
competently designed DACs today have way less than .1 percent harmonic and intermodulation (IM) distortion! You want some "coloration"? Add a tube output stage!Then why do a lot of these dacs  with great measurements sound etched and give me a hea... 
Using solid state rectifiers on Cary SLI80 Amplifier
I'm running a super rectifier with Taylor 866a tubes to power my preamp, I know a preamp doesn't need this much juice, but it really made a big difference in the sound. My preamp sounded really good before the super rectifier, but now it's so much... 
Using solid state rectifiers on Cary SLI80 Amplifier
oldhvymec: the 866 is a mercury half-wave rectifier tube. It must be warmed up first before any B+ voltage is applied! Otherwise it can explode! Anyway two are needed for full-wsve rectification.I run two 866a's in my super rectifier, it has a sta... 
Using solid state rectifiers on Cary SLI80 Amplifier
Your willing to give stuff a shot, try a super rectifierOldhvymec I was going to suggest that but people on here will think I'm just a fanboy, but it would make a substantial difference in the bass if he ran a super rectifier with 3b22 or 866a tub... 
Using solid state rectifiers on Cary SLI80 Amplifier
Can you use 5ar4 rectifier tubes in the cary amp, they have less voltage drop than the 5U4G 
How To Do You Measure the Quality of Your AC Power?
I've never encountered a ground loop from running more than one dedicated outlet, it would be rare. I think some mistake noise in the system to a ground loop. 
Threshold T-200. Help me choose a preamplifier
The bewitch sn3008 tube preamp has an output impedance of 10 ohm’s, they might be available in Russia.

Free Shipping - Be Careful!
I've ordered quite a few tubes from many different venders and they all used USPS, free or not, never had a problem. 
Threshold T-200. Help me choose a preamplifier
If the input impedance of the T-200 only 926 ohms, the required output impedance of the preamp should be much lower!I would think that about 50 ohms would be safe or the op could just use go unbalanced. 
Threshold T-200. Help me choose a preamplifier
Stereophile measured the input impedance of the T-200 at only 926 ohms. 
How to get into high end digital? (Feeding a DAC)
Pure digital is totally accurate but not everyone's cup of tea. We are influenced by our pastNot true nothing in audio is totally accurate. Solid state has distortion also, it's just not very pleasant to the ears.
