Preamp Deal of the Century

Ooslik...I find it interesting that you mention the following: "...the impression I am getting is that the transients are a bit faster with less glare throughout the musical range." I have burned in for 200 hours both the line and phono stages of my Cortese. I am still getting what I hear as some glare or harshness in the upper midrange, especially with instruments like trumpets. I did not have this before purchasing the Cortese, which was the only component that changed in my system. Let's just say that my previous preamp, built by an extremely brilliant friend I had known, no longer became serviceable. It too was an extremely fine unit with fairly high gain. Anyhow, I've tried some tube rolling ( replacing Sovteks will Mullard, Amperex, Siemens, etc.) but still haven't scotched the problem. I have yet to try the likes of 6SN7s by Ken Rad, RCA or Tungsol. I otherwise like the Cortese very, very much. It is a superb component. But there is that somewhat "glaring" issue that you've experienced too. I'm wondering what needs to be done to neutralize it. I still do have other options beyond tubes that I've yet to try, but do you, or any others having faced the same issue, have any suggestions---or---have any of you found as solution for it ? Thanks very much.

Opus88,
I think I've experienced similar midrange problem with my Chenin as well. My experience with tube rolling is very limited, but I feel NOS RCA Grey Glass helped in this regard.
I feel that most of the Supratek owners are kind of hush regarding this very issue and reading this thread very carefully, I've come across very few owners posting similar impressions as well.
I'm sure system synergy is very important, and one has to be very careful pairing Supratek preamps with the "right" amp and speakers.
I decided to give it another chance and oredered Cortese and Mondeuse, hoping that synergy will be "right".
Please, do share your further impressions.

I have ordered umbilical cord from Brad on 02/01/2007, every week he is promising to ship it next week. I really hope that this is not a scam. After one month he stopped answering my emails. I called him, he is just about to send it (for the forth time). What would not just he say that there is a 2 month backorder ? Why do some people do not have any regards to what they are saying? No self respect whatsoever....

Sorlowski, I understand how you feel. If Brad really has a problem fulfilling the orders, just say so. I don't mind waiting so long as the reasons are valid and he keeps me updated on the progress but nothing from him so far...
If anyone reading this knows Brad personally, perhaps you could let us know what's happening. Appreciate that.
