Tube pre w/ remote and phono: used 5-$600.....

That is EXtremly Tuff... If you want resonable build and sound your gonna have to strech to about double that. At 600.00 Its gonna be basically With a cheaper phono stage internally(more than likely MM only)and no remote, or with remote No phono, and even then expect with shipping and all that to touch around 700.00... I tried finding the same as you recently and there was basically no way to pull it off without droping at the very least about 850.00 and I think the only stuff I found in that range at all would be something like the Rogue 66. Your probably better finding a tube pre in the 600.00 range if lucky with remote, and add a Music hall, Lehmann, or Cambridge phono stage.. I think new all those run around 99.00 to 150.00. Good luck

You might realize that after the thorough search for $600 full function preamp you won't find better one neither tube or SS to Sunfire SRP which is SS.
It has MM/MC transformerless phonostage(MC has near 65dB!) and excellent noise-free line performance as well.

Not that much choice out there: Quicksilver Preamp, Audcom AP-150 tube preamp (see also TAD 150)

If you drop the remote I would look at:
Bottlehead Seduction and Foreplay combo special, Audible Illusions preamps.

Gmood's idea of hiring a designer to custom built seems a great option too.

Good luck and let us know what you end up with.

Music Reference RM-5.

A used Conrad Johnson PV-5 might fit the bill. it certainly falls in your price range. Very lush, 3D sounding. Only weighs about 12# though. It was a classic in its day..
