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.

thank you all the your responses, cancel the power cord.  will have to just go with tube rolling again.  I know nothing about the 6922 tubes, I come from 12au7.  almarg, don't know a thing about the imped factor.  and do you still have that 17ls.  or what preamp goes best with the dna 500....

@millercarbon   Hmmm.  Must be nice to be THE authority on wire.  We have quite a few folks here who make their own gear including cables and have achieved high levels of sonic reproduction. Who are you to say otherwise???

I purchased some used Bob Carver amps that sounded as you described. Running to Klipsch Cornwall’s. Rolled several sets of tubes. +1 on the new production Gold Lions. I also have Manley tube phono stage. Came with Tungstram 6922 tubes. Didn’t take long before I replaced with Gold Lion tubes. There is a chart on the internet that shows relative gain for bass, mid and highs.  Gold Lion tubes where shown to have nearly equal gain in all three ranges. My listening to some of the others shown in addition to the Gold Lions seem to agree with what was reflected in the chart.

Did you invert both your speaker wires at the speakers?
The ET3 Preamplifier is phase inverting.This is conveniently done by reversing the positive and negative connections to your speakers (be sure to reverse both channels).
When the system is in the correct phase, transients will be noticeably cleaner and more sharply defined. - not all recordings are phase correct so
listen to several before concluding your investigation of absolute phase.       Best
