Tact 2.2 XP: which configuration to get?
OH, and Mr C is correct about the configuration for your outputs(DACs for both mains and subs). Should you ever decide to add analog inputs/an ADC- It's as easy/painless as plugging a soundcard into your PC. 
audible artifacts in output of Tact 2.2X
The TacT's power supply(like any other amp/pre) only can provide so much voltage. When the demand exceeds the supply in the TacT RCS- digital clipping results. I experienced the same when I first began my TacT experience and satified myself with a... 
Tact 2.2 XP: which configuration to get?
The TacT 2.2 units have very little sonic signature, or I wouldn't be using one. The benefits of the room's time domain/response being corrected FAR outway any slight transparency issue. I've just installed Aberdeens latest power supply upgrade(us... 
Does coloring the edges of CD's help the sonics?
(http://www.tweakaudio.com/EVS-2/CD_tweaks.html) Everything in the electromagnetic spectrum has a specific wavelength/frequency, and in most examples, can/will be either absorbed or reinforced by some other wavelength/frequency(if present). Red li... 
6SN7 tube GTA vrs GTB
(http://home.att.net/~chimeraone/6sn7sound.html) I've personally verified the findings of this site. That's why the TungSol JAN CTL round plates, and Sylvania JAN CHS/6SN7W(tall bottle) tubes have found a home in my system. None can deliver the mu... 
Siemens CCa vs. Amperex PW 6922
Mr G- Sounds like a no-risk deal. He must be confident of the quality of those tubes. The $$ seems high, but I've not been tracking the cost of CCa's for a few months. Listen to them and judge if they deliver the value in music. Personally- I coul... 
Siemens CCa vs. Amperex PW 6922
Mr G- Yes: The tubes that my-baby-world is selling are the right ones. Unfortunately: no readings are given for them. The two pair with the $306 buy-it-now price are clocked in the pics so as to hide the shield below the getter support. I would se... 
ARC Ref 3: Tung-Sol 6550 in power supply?
I second everything Bart just said. NOS Power supply tubes can provide a major sonic improvement to any equipment, and there are a number of excellent 6550 iterations out there to try. Obviously- You have the ears and system necessary to appreciat... 
Voltage fluctuations
A power conditioner cannot adjust your voltage higher than what's coming out of the wall socket, unless it is a regenerator. Those are designed to generate the proper voltage and eliminate fluctuation, IE: (http://stereophile.com/powerlineaccessor... 
How do you clean tube pins?
The EXACT SAME principal(common sense) applies to the use of contact cleaners and contact enhancers, but neither of them will remove the very thin anti-corrosion plating(gold, nickel, etc) that most tube pins have. Steel wool(no matter how fine), ... 
Siemens CCa vs. Amperex PW 6922
Mr T- I couldn't agree more about the risk involved buying NOS CCa tubes, or any others for that matter. Finding someone that has the right tester, knows how to correctly use it and is honest about the results is becoming increasingly hard to do. ... 
Siemens CCa vs. Amperex PW 6922
There are opinions, and then there are facts. Siemens made no CCa's with shiny plates and internal date codes in the early 60's. From the 50's through 1965 they had the dull grey plate(electrostatic shield) under the getter support. From 1966 to t... 
Siemens CCa vs. Amperex PW 6922
At least you're at the top of the digital ladder. No doubt about analog(done right)though. I SO miss the days when direct-to-discs, original master/virgin vinyl, 1/2 speed mastered, MFSL, Sheffield, Crystal Clear, TELARC, JVC Soundstream, Nautilus... 
Siemens CCa vs. Amperex PW 6922
Andy thinks the people that know about the older CCa's are nuts because all he has to sell are the later ear-hair-burning versions. Not hard to figure out: Ignorance is bliss, and profitable too. Enjoy whatever you settle on. 
How do you clean tube pins?
Any slight corrosion should get rubbed off the contacts when the tube is inserted, most are nickeled anyway. The ProGold or SST on the tube pin actually then somewhat seals(capillary action) the contact point, inhibiting oxidation. I've used small...
