Preamp Deal of the Century

I´d like to recommend two products that I´ve tried lately and that in my opinion help to improve the sound.

The first one is the Foundation Research power cords, LC1 and LC2, (thanks David). I use them in my cd player, Syrah, and Cary 805c. I can´t say more then the sound is cleaner. For me it´s enough and that´s what a p.c. should make.
Last year I sold a Shunyata Anaconda Vx power cord because in my opinion colored and tamed the sound.

The other product I´d like to recommend are the HAL-O damping instruments. They help in the same way, the sound seems more defined and cleaner. I use it in every tube I have and you can sublety modifie the sound puting them in one tube or another and even with the position in the tube, up or down. Play with it.

I forgot to thank Jazzdude, he was the first one to let me know about the HAL-O damping instruments and the first one to talk about it here (i think).
Thank you, Jazzdude.

Brian,

I would be interested to know what Nick would do and what it would cost. I have a Cortese (about 2 years old).

Have you figured out whether you are moving ?

Hi Larry, Looks like I am moving at the end of February. I'll be in temporary / corporate housing until June. Then I will start looking for a house.

Supratek modifications - update on this idea. Since I posed the question to the group, I've received numerous replies & have also considered the concept further.

I am not certain if it such a great idea & here is why:

Supratek's come with a life-time warranty which would most likely become void should there be any modifications performed. Prior to doing anything to a Supratek, you should contact Mick to get his thoughts on what you plan to do.

In my conversation with the audio engineer, he stated there are many reasons why Mick did what he did in order to accomplish what he has. He suggested that he would not be able to "give us back" the results he would want to give because there would be too much design work required to improve on what Mick has already accomplished. He suggested the best upgrade or modification "circuit wise" would be (if you love the preamp) to upgrade to a higher level model.
