can someone answer me this.....

i have done some extensive research and talked to quite a few people who own or have had this preamp.  I recently came into a conrad Johnson et 3 se, nt much clarity,the bass is muddy and the presentation is dark, ive read where some claim the system is to bright.  ive also read where its good to get a specific type of tube.  I don't want to do that just yet because im trying to learn the units characteristic.  I wonder if its not quite broken in yet.  maybe the impedance thing that Im just learning.  steve mccormck suggested that I try some after market power cord, that I ordered.

I have an old CJ Classic pre, and always forget to invert phase when shifting it around. I've even written "Invert Phase you Idiot" on a label on the back :-)Hopefully your problem is as simple as that.

I have also played with the valves over the years, and agree that they can make a huge difference. Some new manufactured one like the JJs and Electro-Harmonix make the Classic too bright for me. I have ended up with some NOS Mullards that sound just right. With the right valves, my pre is definitely not muddy and dark.
Good luck.

A combination of bad tubes and a source component (Oppo 203). Replace the bad tubes and upgrade from the Oppo 203. 
I think the Oppo 203 is your weakest link in the chain. Front end source component(s) are the most important element in hifi chain.
