Tubed Pre to mate with W4S monos 1K budget

Juicy Music Peach I or II. I recommend version I that uses 6922 tubes rather than the 6H30 because the 6922 version gives you options for tube rolling.

The Peach is no longer made, so you'll have to wait for a used one to show up. They sell for $600-$800 depending on condition and seller motivation.

No remote.

There are a few Rogue Mag 99 preamps for sale. I prefer the sound of the 6SN7 tube versus 6DJ8/6922 tube sound. I recently installed a few of the 6SN7 NOS tubes that I owned in a friends Rogue 99 and the preamp became very musical over the stock 6SN7 tubes he was using. The CBS 6SN7 GTB tubes are cheap and work very well in the Rogue. I have never owned a Rogue product.

Try a Manley Shrimp, they usually pop up for around $1000-1200 used.

The AE-3 from AES is super IMHO. The in DJH edition runs in your price range or even less new (I have seen them at Upscale Audio). It uses 6SN7s primarily which allow for a great deal of experimentation with many around to roll. Got mine used here for very little in plain original guise, then had it upgraded.

A VTL 2.5 is one I owned around $800-$850 used. It was quiet and a very good and solid preamp; worked well with my W4S ST-1000.
