@corelli The LTA preamp works well with the solid state Coda amp. I like the combination, anyway. It replaced a conrad-johnson preamp. It's not a real warm sounding tube preamp compared to the older conrad-johnson, but I prefer the sound of the LTA. Excellent detail, imaging, and soundstage.
It responds well to tube rolling. And, tubes last a long time.
I'm not very good with describing the sound.
