Preamp Deal of the Century

Anyone heard the GEC copy KT-66 by Shuguang from China?

Just purchased a used Syrah and so love it. Mine is a little different in that in has a three tube power supply just like the Cortese. My question is about a power cord and which tubes, line stage, are most influential on the sound. I would like to tube roll for a little more bass impact. I was using my Opus 21 CD player directly into my Parasound Halo JC1's monoblocks. Sound is also so very good. I then put the Syrah in and found more detail and emotion in the music. Beautiful is the word for the sound of this preamp. I did however lose a bit of bass impact and weight.Not sure if a cord or tube roll will help me get that back. I prefer every other area of sound with the Supratek pre in the system. Just lost a little bit of dynamics and bass weight on my Khorus X11 speakers which go down to 17hz.

Grannyring, what tubes (names & model numbers) do you have in the Syrah now? It is possible to get more bass impact, weight and body by tube rolling in the Syrah. I just need to know your tube compliment to get an idea where you're starting from.

In the power supply,
2 - 5881/16L6WGL Sovtek
1 - 5Z4GT Phillips

Main unit,
2 - 6C45N-L - No brand name I could fine but the tube # was in a design that looked like a tube.

2 - 6L45N - E - Same company as above

Hope this helps. Pretty sure they are all stock tubes and the unit has not been retubrd from the factory. Built in August of 2001.

Thanks,would a AC cord help - you use a Moray cable I have never heard of.

Thanks,

Cottection, the main unit has all 4 smaller front tubes the same,

6C45N-E,

I incorrectly thought two were (-L) however they were (-E) rubbed out a little.

Thanks,
