$1600. preamp

Spend around $1,000 and look for a ModWright SWL 9.0 SE or spend a little more than your budget for the LS100.

I think the Manley would be a great buy, a new one with remote retails for $3800 used $2,000 all day, the Shrimp was a earlier NON remote version so it was less. The circuit design is very simple and it can drive any amp (200ohm output). Also, The sound is amazing!  The ModWright is a great pre amp as well. I have had both in my listening room, the Manley Shrimp is still in my system and the ModWright is in my fathers system. They are both great deals indeed! I owned a Quicksilver pre amp in the 90's, seemed a little cool and dry for a "tube" component IMO. I sold it.

I'd add a few $ to get BAT VK32.

I bought a Manley Shrimp years ago on here for about $900. I had it for about six months and truthfully I didn't think it was anything special. I sold it for about what I paid. Shelling out $1600 now would be a huge overpay.
