What Power Cord can improve clarity and bass slam?

The kinds of differences you guys are talking about require changing gear, not cables. I think I'm "almost" with Bryon.

Csontos -

Re-reading my post above I agree the differences are described in a way not corresponding the subtleties at play; however, the nature of these differences still holds - and are in fact audible to an extend that I find them worthwhile to pursue - but in a more downplayed fashion than my words would (mis-)lead you to believe.

Perhaps it's the nature of describing "minutiae" details(minutiae to some, I guess), and how one blindly focuses on or even magnifies impressions (in the wake of intense listening sessions) so to illuminate them more properly, disproportionate they may seem. In that manner of "wringing out" details it may also be indirectly assumed, on my part, that the receiver understands or presumes this very context himself in how he would've gone about it, and hereby "reverse-deduces" these impressions to their more correct of proportionate interpretation.

No excuse though, it should be clear what's at play without assuming anything, or at least too much on the part of the receiver..

I believe the answer to be "none". It doesn't matter a bit, unless you are planning on upgrading all of the Romex in your walls as well with $500 a foot cord, how would upgrading the last 3 feet matter at all?

Another point, if your amplifier is properly designed, it will have capacitive reserves that more than make up for the types of effects spoken of in the above posts.

Try changing the receptacle. For the sound you are looking for I'd recommend trying the TeslaPlex. I'm pretty sure you will hear a significant difference from the Oyaide.

Dayglow- Since your first post and my response, we have changed the breaker panel and added a dedicated 10awg romex to my temporary bedroom system with Wattgate gold receptacle. Current TelWire is using gold Wattgate ends on their Reference cable.

The huge differences between cables on the cheap receiver, together with Parasound amp is much less now with the dedicated circut. Trying 5 or 6 different cables, Telwire still good, but other cables now at least listenable.

My advice is going to match others with going to dedicated circut (only cost $100 added to the other work), before any other changes to system. Mike
