Are there any budget tubed preamps that stand out

I have a solid state mono block set with only digital source. I run Apogee speakers.
I have looked to Norh, Audio Mirror, and some others and need to be less than $700. Much less if possible.

How about a Bottlehead Foreplay kit or a Transendent Sound pre kit. There is a EAR 534L pre for sale now for 595. A used Quicksilver line stage, or ? I think these are all better than most new $700. chinese preamps. Lots of nice used preamps out there.
Dared SL2000a. You should be able to find one used for ~$300. The one limitation is 2 inputs line stage only. OTOH it has remote volume control.
