Which Power Cords: I Need Some Informed Guidance

I have observed the following changes during break-in.

Increased top end extension.
Less top end harshness.
Increased image size.
Increase low end extension.
Better defined bass and bass clarity.

The changes may be subtle. They may be dramatic. Based on comments in
Audiogon threads regarding break-in effects, the degree of change varies
from system to system, and from listener to listener.

I've been on the powerchord train for awhile and just got off. Two Shunyata Taipans for my SimAudio monoblocks. Audience powerchord for my DAC and Audioquest for Sonos. I'm happy with all the choices so far. I notice a much much lower noise floor. Looking forward to the Shunyata SR- Z1 outlets. Those heavy cables can sag from the sockets. Don't forget your outlets guys!

Why doesn't anyone use or recommend SR Master Coupler any more? These cords were among the first aftermarket cords that became popular. I still use 2 on my digital front end....just curious.

Tvad is right on with his statements. And in my experience
replacing the stock powercord makes a bigger difference
then interconnects or speaker cables. The trick is to
find the right one for each piece. I have a Krell and
a Unico Int amp and the powercords that each of them
like best are different and cross switching them yields
poorer sound for both amps. Truly maddening..

Upgrade Powercords seem to do some or all of the following:
1. Filters out A/C noise
2. Rolls off the highs OR tips them up.
3. Tightens up the Bass
4. Speeds up or Slows down the music's pace.
5. Becomes Capacitive which I believe is what increases dynamics.

Lot's of F'n voodoo going on here for sure..

Like everything else in high end audio, the crowd gathers around the latest "hot buzz" component (wire, tweak, whatever) that's receiving raves, and quickly moves on when something new gets the spotlight. Audiophiles are nothing if not fickle and desperate for the latest-and-greatest.

It doesn't diminish the quality of what went before.
