Best Tube Preamp with Phono under $2000 ?

Thank you everyone for your comments. They have helped me immensely in identifying the various options I have at this price point.

Some of you asked about the AMP these will be connected to. It will be connected to two Monarchy SE100 MK2 Monoblocks.

The rest of the system is as follows:

Sources:
Musichall MMF 5.1 turntable with the Goldring 2200 MM cartrige
Cabridge Audio DAC with Sony PS3 as transport

Pre Amp: Onkyo - but looking to upgrade

Interconnect: Kimber Hero

Amp: Monarchy SE100 Monoblocks

Speaker Cable: Supra PLY 3.4

Speakers: NHT VT 2.4

Thanks,

There is no info on the Monarchy website regarding input impedance of the
SA100 monoblocks. I strongly suggest contacting Monarchy and obtaining this
specification before purchasing a preamp. It's possible that some tube preamps
will not match optimally with the solid state Monarchy amps. You need to have
this information before writing the check.

*That's an easy one; Cary Audio SLP98p, used--Macdadtexas*

I 2nd the Cary Audio SLP98. I've had one for a few years, & love it. Mine doesn't have the phono stage tho; I used a C-J SS phono stage with it & that was a nice solution. The thing with Cary gear is, almost all of it sounds great.....

The input impedance of the SE-100 is 40Kohms. I was told that it should work well with any pre-amp between 50 ohms and 50K ohms.

How does this limit / expand the available options?

I don't think the 50K ohm figure is correct. Perhaps they meant 5k ohms.

In any case, with a 40k ohm input impedance for the SE-100, most tube amps will work, IMO, including the Cary SL-98p that has an output impedance that rises to 6.8k ohms at one point (according to John Atkinson's Test Measurements section of the Stereophile review).
