Power cords and soundstage


So I made a couple of changes in my system yesterday. I've acquired new power cords, and replaced/rearranged the power cords for two of the amps.

By the way I consider myself as semi-skeptic and semi-believer of good cables. I've heard subtle difference and improvement on some of the cables. But in most cases either I can't reliably tell which is which, or if I can tell the difference it is very small. I don't own exotic cables. Some of the brands I own include Audioquest, Kimber, Analysis Plus, and a few home-brewed, but well received power cords.

When I changed the power cords yesterday I heard immediate, and distinct difference. I can't say whether I like or dislike the changes yet, but the change is unmistakable.

Even my wife, who is music enthusiast but indifferent when it comes to the system change, commented today and said she thought the center speaker is "too strong". I've then explained that there is no sound coming out from the center speaker with the CD that she was listening.

Some of the differences that I've heard with the new power cords are the following:

Bass: Immediately I heard and felt that the amount of bass from the main speakers were smaller. It is definitely less boomy, and became tighter. I'm afraid the bass doesn't extend as low as before. So I've gained some and lost some.

Focus: focus, soundstage, whatever you call it, has tightened up as well. The bright side of it is now the speakers have completely disappeared. However it doesn't sound as extended from left to right as before. And as my wife noticed the sound is seemingly coming out from the center speaker, although the center speaker is off. No, I didn't hit dolby pro logic button by mistake. The only speakers that are producing any SPL are left and right speakers. The instrument location is still clearly defined, but overall left right soundstage is now much smaller. Here again, I've gained some and lost some.

Depth: This is one area that clearly was improved. It may sound like a cliche, but the noise floor seemed to have decreased, there is more micro dynamics, and it sounds deeper.

Now I'm more confused than ever, and I'm questioning my sanity..

TVAD...As I said in my above posts...the ends make more of a difference than does the cord itself. I suspect the Gold/Bronze/Gold is a good combination...I have the 046 which uses Palladium. Give it a couple of weeks. I have remarkably wide and deep soundstage, and I truly can hear instrumental parts I never knew existed on my records that I have heard for 15 years.
I am aware you said the ends made more difference. You had written that in your system, the 079 sounded too warm in your system, and since this is exactly what I was seeking I purchased the 079 connectors rather than the 046 connectors.
Well, I've decided to return the Acrolink/Oyaide 079 cord in favor of another
Oyaide Tunami GPX. In my system, the Tunami has better balance and is less
aggressive in the highs and upper mids.

I'll now have Tunami GPX on all my components except for the APL Denon
3910.

I've been through a lot of high dollar power cords, and in my present system
the Oyaide Tunami GPX are outstanding, and they're crazy good bargains
compared to just about everything else I've owned.
TVAD I am glad that Tunami works for you. We must all remember that power cords are very system dependent. I have absolutely silky smooth and realistic highs with the 046/Accrolink cord..a better match for ME in MY system than the Tunami. There are no absolutes in this hobby and we all have to experiment to find our own private jewels..the discovery of which makes this hobby so exciting.
