good preamp for First Watt F7

Hi everyone,
I'm looking for a good preamp for my First Watt F7 amp.
I'm using now my PS audio DS DAC as an preamp.
F7 has input impedance 10K Ohms, gain of 14 dB.
862efa81 c5db 426d 88a0 ab128b970b24bakalovb
Rogue Audio RP-5. Output impedance: 500 Ohms.

What's your budget?
And SE preamp I assume?

Linear Tube Audio MZ2. Sounds great with it, output impedance 50 ohms.
the budget is around $1000 (to compete with Freya +), might be tube or SS

You need a little gain also with the F7 being only 14db.
Just go with the Schiit Freya-S or Freya-+ both have 75ohm output impedance on rca on their active stages and a gain of 4, and should drive the F7 no problem. Stay away from the Schiit Saga's as they are only unity gain.  

Cheers George
