What Tube Preamplifier Under $1800 to Choose?

I've enjoyed my Audible Illusions Modulus 3A paired with SS amp.  You can find used in your price range.

+1 @coos that deHavilland is the steal of the Internet. I'd almost buy another one just to have it. The review by Dick Olsher says it all.

About 20 years ago the great J. Gordon Holt pronounced the sound of the Berning TF-10 pre-amplifier so exemplary as to make further advances in the art unnecessary. That judgment has proved to be premature, so wisely I will not go that far. But having lived with some of the elite high-end pre-amplification from the likes of Jadis, Sonic Frontiers, and Air Tight, the deHavilland UltraVerve is currently my first choice in line amplification. At a retail price of $2,495 it upsets the ultra high-end applecart; the point being that simple, minimalist, well-engineered designs can rise to the top while being quite affordable. Low on parts count, but high on tube magic, the UltraVerve scores big in my book.

This is easy , No doubt Galion P75.I already have Galion TS 75, and the Galion discovery mono block. Now Iam thinking of getting P75 ,  or even the navy preamp.Thomas gear are musically exceptional .I might get the navy preamp if budget allows instead of the p75.

Schiit Freya+ all day. I like the tonality of the 6SN7 tubes as well.
