Tube/Hybrid Tube Preamps Below $2000


I pulled the trigger on a ps audio s300 power amp and the new klh five speakers. I can’t wait to set them up, but I can’t decide on a preamp. I’m new to tubes and separates, and this seems like a good opportunity to add some warmth. At the moment my short list is the rogue audio rp-1 and the van alstine fet valve cf rb. The cfr looks great, but pushes above $2000.
The rp-1 includes a phono stage which is a plus, and rogue seems to have a great reputation. Rogue audio often pairs tubes with class d amps, so it seems pretty safe that it’ll pair with the s300. RA is a PA company which is a plus.
The fet valve seems to have great reviews too, and it uses 4 tubes instead of 2 (this isn’t necessarily an advantage I know). I also like the simplicity and look of the fet valve better than the rp-1.
I was wondering if anyone had experience with either, or even both. Also, any missed options? Is the Doge 7 worth considering? The Doge 8 is just a little too much. I’m not opposed to used, but warranties and return periods are a big advantage. Van Alstine’s in particular seems great

I have and use a turntable, but I’m not opposed to an external phono amp. I’d prefer a phono input, but it’s not a dealbreaker. A remote would be nice, but it’s not a essential. Initially I didn’t want one, but the more I think about it, the more sense it makes.
I run an RP-1 and the S300 combo. I upgraded the RP with some Mullards and like the combination very well, RP-1 is solid sub $2K Pre. I also have a Rega P6 source with a MC cartridge. Manual for the RP-1 was a little confusing to me (electro dullard) to set the dip switchs so I called Rogue and they helps me set it up based on cart specs. I also source Qobuz/Roon/BrystonPi/Wadia321 and that rivals my P6 in SQ pleasure. If you are patient you can pick up a used RP-1 But they gets snapped up purdy quick. Only knock the RP-1 is a cheese whiz plastic remote. :/.
Edit: RP-1 also has a configurable headphone stage.


The aric audio unlimited looks solid. Would be the most pure tube pre I’ve considered, but I’m interested. The adjustable gain is a nice touch. I wasn’t able to find many reviews, and how it holds up to others.
save a little more and get the rogue audio RH 5 headphone amp balanced line stage. an excellent sounding preamp and a value at its $2500 msrp.
sold mine and sorry that i did.  took gobs of $$$ to improve on. 
@lakeofthewyles So far I've only had one formal review of the Unlimited II by Enjoy The Music, however there is a thread on Audiogon where several users have commented on it below:
