Modern Linestages
The perfect linestage can be imagined as simply a wire with gain. If you do not need gain a passive preamp will do. So, you ask what about matching impedances? Well a simple buffer can be used. Enter the First Watt B1, a passive volume control wit... 
Having an ear for Jazz
To the thread starter,You have described my sutuation to a tee. 
Why We Need Audiophiles ?
So the high-end power cable and speaker cable manufacturers can stay in business. 
Do powercords make a difference in sound?
I think that if the power supply in your component is designed properly and the stock power cord has sufficient gauge to deliver the current demanded by the component there is no advantage to upgrading. 
How Much DC is OK on a Power Line?
6550,That is exactly the type of response I would have expected from you. Sad, just very sad. 
How Much DC is OK on a Power Line?
It matters if you don't want your power supply transformer to hum loudly. If you are trying to be a smart ass, all you have done is made a ass out of yourself. 
Differences between various Quantum devices
If I read their web site correctly it seems that they are simply filtering or "Cleaning the mains".From their website:"QRT’s proprietary circuitry acts at the source of the problem, reducing EMF noise and RFI interference effects on the mains wave... 
QRP pressing of "Tea for the Tillerman"
+1 I have purchased the recording. It has really opened my wifes (big Cat Stevens fan) eyes to what I am trying to accomplish with our system. It is one of the best recordings I own. 
How Much DC is OK on a Power Line?
Most hum on power transformers is caused by DC on the power line. The source could be anywhere. It could be caused by a poorly designed switching power supply in a Television or a light dimmer. You can DIY a DC filter to take the DC off the power ... 
XA 30.5 or mod S/500?
The big advantage of the XA30.5 is the SuSy [super-symetry]circuitry that Nelson patented. Here is the url:http://www.passlabs.com/pdfs/articles/susy.pdfI don't know if the XA30.5 will drive all the speakers to volume levels acceptable to you. 
Do you understand your amplifier?
I see questions like, "I am looking for a tube like solid state amplifier"? Would it not help to understand that MOSFETS are voltage sensitive very similar to tubes and used in a class A biased configuration can be made to sound tube like with ver... 
Anyone tried Quantum Resonant Technology?
Actually the device is an EMI and RFI filter. With a little engineering saavy and a few dollars, a DIY filter can be made with comparible results. Most of these products utilize a common mode choke and an Isolation Transformer configured to elimat... 
pre vs amp power cable question
If you have power cords of sufficient gauge to supply the current required of the Amplifier under worst case conditions and the power supply is properly designed you will have a difficult time telling the difference between any of them. Class D am... 
Isolation transformer - does it offer protection
In an isolation transformer the output winding will be isolated, or floating from earth ground unless bonded at the time of installation. Secondary neutral to ground bonding virtually eliminates common mode noise, providing an isolated neutral-gro... 
pre vs amp power cable question
The easy answer is the more current required, the lower the gauge wire is needed. It is that simple. With that being said, it does not hurt you to use a low gauge power cord on your preamp. IMHO, it will be difficult for you to tell the difference...
