Romex to your amp?

@Gongli3... That's what I did.  Ran dedicated romex runs direct to the breaker panel... all in steel conduit.  The 'noise floor' dropped to nothing.

Do people know that transformers in linear power supplies are pretty effective at filtering high frequencies?  Any idea the ratio of the inductance of 40 feet of house wire versus a transformer leakage inductance? 


How about likely the most critical aspect is ground continuity between equipment?


I am curious what, in all these theoretical ideas do people think they they are improving and what is critical? 


Solid wire is used because you don't get loose strands or broken strands, not because it conducts better.


With a small power transformer bandwidth, why do we care about 5 -9s copper or crystal grains when people who make 10ghz+ cables don't?

Makes it little sense to me. What is going through the Romax is what I'm cleaning up with the 3 - 6' power cords. Why would I want to extend that to my amps? YMMV

My 4 gauge dedicated line is soldered to about an inch of pure silver stranded wire that acts as a fuse and is in turn soldered to the panel bus bar. Oh, did I mention its 240v? So each leg same thing. Then at the other end just below the room its hardwired into a step down transformer with another hard wire coming out bringing 120V into the room, where it does not come out a receptacle, the wire continues directly into the power conditioner. 

A good SR receptacle and power cord would be a lot better than the romex. Also cost a lot more. So its a trade off, and I know it. But, extreme? "If you say so." Lol!

Not true we tried this and sure it is more direct but you have no protection ,for one, or conditioning ,#2 the wire is a Garbage 
you can get much better wire from. Analysis plus awg11
sure it may cost you $$ but direct still direct to component Bad idea. For all the garbage on line even from the box log to Vh audio 
they sell excellent components,and Cryoed wire for this type of thing ,conditioning  from the circuit breaker box ,with the upgraded
wire. This is a much better method,all it takes is one big spike and 
your amp is toast,the fuse is good for mainly small internal overloads.
