What's wrong with my Cal Delta/Sigma?

JK, I am definitely getting some low noise tubes.

Ton, I am not familiar with tubes at all, but you think the large plates is responsible for your increased soundstage? I did some research, supposedly those tubes your using were custom made and somewhat rare. Also, being on a tight budget, I've been dwelling on taking a chance on cableplex powercords or the ps audio minilab cables since they seem to offer tremendous performance for the money, $199 for 10 awg, 3x shielded (boy, i am starting to sound like one of those absolutepower ads).

The Tubes are available at www.upscaleaudio.com, I think they were around $20 each. They have a whole lot more if you want tho spend $$$. As far as increased soundstage, I think all of the upgrades, tubes and cables, made a contribution to the sound quality. I had the tubes recommended to me by Matt, the guy who makes the Cableplex cables. I am not familiar with the PS Audio, but for the money I think you will not regret anything from Cableplex. I have an Audiophile uncle who just upgraded his entire HT, and His daughters HT, to the cableplex Nirvana cables. This includes a special subwoofer cable.

As you can tell, I can't say enough about the cables, this is my personal opinion and the biggest enhancement to my system.

Good luck with your decisions

I reinstalled my stereo today. I gave it my best effort to separate the audio and power cables, I've cleaned all the contacts with an alcohol solution (eye make up remover has amazing amounts of alcohol presents, and many differnt types of alcohol too). I moved the transport/dac away from my power/pre amp. And, now, my system is free of everything it was plagued by. Thanks for all your help!
BTW, Monster reference2 is not a bad digital coax. Beats the hell out of the Monster datalink100 I was using.

Good to hear that it just needed a little tender care. I have to do the same thing to our bedroom system that has been laying around in pieces for the last month.

Just wanted to share, I received my Silver Serpent in the mail today from BetterCables.com. It's installed, and I am wreaking the benefits, BIG TIME!! My system now is producing "AIR", "TEXTURE", and probably some hateful neighbors because their is more bass that seems to go deeper with more stress (excitement).

Yah, Yohji is now Viggen.
