Audio Horizons TP 2.0 Preamplifier

This thread has drawn me to consider this preamp. I currently use my Transporters volume control straight to my Nuforce 9 SEV2's. Now I'm thinking if sending my TP to Modwright for the tube output stage and trying the AH 2.1.
I was thinking about the Modwright 36.5, Parasound JC-2 or the Antique Sound Labs Flora. I wonder what the advantages\disadvantages are between these fore mentioned pre's? I was hopeful for HT bypass but it seems these manufacturer's bypassed that option - no pun intended.

RX8man, Did you here a modded TP through the Audio Horizons/Nuforce 9SEV2 combo? I'm ready to ship my TP to Dan for the tube output stage. But that's still a 2K upgrade! Since I don't own a pre, I seem to be spinning my wheels between modding the TP and adding a pre, or both.

I guess I'm just looking for the best combo to pair my current TP and Nuforces. I've only owned 1 tube pre in my life, an AR LS15. It didn't pair well with my Nuforces.

Is it my imagination or are there some excellent 3 to 5K offerings in the preamp world these days?
