How would you introduce tubes into this SS system?

I have a Rotel RC-1070 preamp and a Parasound HCA-1000 amp driving a pair of NHT Super Two’s. The Super Two’s sensitivity is 87 db (2.83V at 1M), 8 Ohms nominal impedance (3.8 Ohms minimum), and recommended amp power of 25W/ch min. and 175W/ch. max. The Rotel’s output level and impedance are 1V and 100 Ohms, and the Parasound’s input impedance is 33 kiloOhms. The budget is around $2000 for either a tube preamp, tube amp, or integrated tube/hybrid amp. I like the sonic qualities of tube equipment, but I don’t want to sacrifice too much bass. I should also mention that I use this system primarily for listening to vinyl on a Music Hall mmf-5.1 turntable. Should I replace the Rotel, the Parasound, or both? Thanks for your opinions.

Not sure if these would be outside your budget, but I know they’ll sound fantastic with the RM22s, and the bass will be sublime as will the imaging/soundstage...

Well, I've done the thing and gotten the stuff. Ended up with the AR LS16mkll, a McCormack DNA-1 Deluxe Edition, and the Joseph Audio RM22si's. Haven't listened for more than a few records as of now, but the combo sounds fantastic. Thanks everyone!

For the record Steve at VAS repaired one of the two amps that I mentioned earlier at a reasonable price and effectively. Turn around time was good. No problems. Apparently I was wrong about his no longer being a distributor for Cayin.

The MCormacks are great amps.  You'll love it, and Steve McCormack still services/upgrades them.

@jackalope -- any updates?  If you haven't already, try pulling the Josephs 4-5 feet into the room if possible, with the speakers aimed at the outside of your shoulders.  Magic starts to happen there.
