PSVANE Discussion & Impressions Thread

I have to say these Horizon 12au7’s are really nice! More full bodied than the Amperex BB’s I had in there. Given the rest of my system (now using LRS+) the increase in warmth and pace is welcome. Really nice. The previous tubes were kinda thread bare in comparison.

I am surprised that you observed the Horizon 12au7’s sounding more full bodied than the Amperex BB’s.   I thought that it would be the other way.  I think that the tube sound is very system dependent.  In my preamp, I found the Horizon 12au7’s sounding nice and clear but a little thin for my taste.   Re-issued Gold Lion 12au7’s have fuller midrange, tighter bass, and more holographic sound.

Our recommendation is to burn in the tubes for about 50 hours to allow them to stabilize. 
During this burn-in period, if you notice that the sound remains consistent without significant changes, it indicates that the tubes have reached a stable state. 
While we suggest 50 hours, it's not mandatory; some reviewers find that 4 hours are sufficient.

@ampus 

What is your preamp? Mine is a Backert Labs Rhythm 1.3+ (has the brass plate). I will add that this is with only a few hours on them so far, but hope it doesn't change.

Thanks!

i cant believe youd say something like that, @alightronics.  they do this kind of thing all the time. havent you ever ordered anything from amazon? they stick records in envelopes.
