Tube Cd players, Gains and Losses.?
I think Hackmaster pretty much hit it on the head. 
Verity Parsifals vs 1st series Talon KhorusX
Two completely different animals. What type of music do you mostly listen to? 
Mixing SS and Tubes
If I am not going all tube I prefer tube pre-amp with solid state amp. 
De-Emp and Direct Which to Use
You use direct on Audio Note DAC's. 
Do new tubes undergo break-in like other devices?
Yes. Tubes do burn in. We find anywhere from 25-100 hours depending on the type of tube and the equipment used. Some gear draws a lot more current which tends to break them in quicker than low voltage devices. 
De-Emp and Direct Which to Use
What brand of DAC? On ours we usually use direct. 
De-Emp and Direct Which to Use
Which DAC are you using? 
Review: Audio Note DAC 3.1 Balanced DA converter
FYI,The unit is still transformer coupled even when run single ended. In fact Peter Q. Runs his single ended. The transformer coupling makes a world of difference.

Hi Sean,Are you saying that if they are not measurable and scientific that our ears are wrong or the findings irrelevant?I am not a engineer. I am and have been a avid audiophile for 32 years. While I can't explain why power cords make a differenc...

Seandtaylor, While I tend to agree that theory should be relevant in analyzing certain aspects of audio, my experience has been otherwise. As an example some theorists will say that a power cord brings ac to your component. How can this possibly a...

TWL and Sean are correct. This guy is clueless. No pun intended to our very own clueless:)I took just one piece of his so called work which stated that:XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXMyth: Replacing the resistors and capacitors in preamps an... 
Transformer coupled / Capacitor coupled
Clueless,I believe per the article that the transformer application he is attempting is in a passive device. I think that is why the active transformer coupled pre's don't have that issue. They are 600 ohm instead of the 50k or 100k many actives u... 
Transformer coupled / Capacitor coupled
The issue is more than just impedance. As capacitors drain during dynamic passages you will hear it as strained or harsh sounding. In addition, many manufactureres use cheap capacitors. That being said even the best have a sonic signature. I will ... 
Transformer coupled / Capacitor coupled
Interesting article. Learn something new every day. Unless I'm reading this wrong you still have some impedance issues. Is this correct?
