tube upgrade for first sound

Hi Bob
First Sound it is! Don't have it yet. Should be acouple of weeks. I'm keeping my fingers crossed. :-) It meets all of the technical issues I have regarding DC leakage and all. I've tried 2 other tube pre's as well. I've been climbing the ladder. This is the end for me, no matter what. I hope this is "the one". :-) How is your Supratek?

oldpet tell us more about your system. There are a bunch of highly satisfied FS oweners here - we want to know more about your rig.

Also, allow the thing to break in at east 3 weks before coming to any conclusions - AND REMEMBER IT INVERTS PHASE, so you need to account for that.

Yes, it inverts absolute phase. This is different than the out-of-phase
most of us are familiar with in which the imaging out of whack. I
pesonally can't hear the difference with a unit out of absolute phase and
in absolute phase, but I don't really know what to listen for either. Artg,
can you hear the difference?

I can't hear the difference either, and there's the POV that half of all recordings are inverted anyway. But I have my speakeer leads reversed at the amp just the same as Emmannuel Go is quite insistent about this.

And Paul, as many have mentioned, plug it straight into the wall. After a while, you will want to play with aftermarket power cords.

Id be lying if I said I could always hear the difference, but on some, the bass is off. On other recordings, i cant tell. Mostly i bring it to your attention because emmanuel really really feels strongly about it....
