Dan D'agostino classic stereo amp + Dartzeel NHB-18NS

Wonderful combo will sound great enjoy and be well.

tube like warmth

??? That means colouration to me. It should sound the most neutral, compared to others.
If it behaves anything like an LDR based passive volume control which it sort of is, it does have a small gain section which I believe can be switched out, then it should sound like a direct source to poweramp connection, a transparent and dynamic sound, with the least amount of colouration, given a great impedance match, that you have.

FWIW I mated a Krell Phantom two box pre with my  Agostino  momentum amp. Actually directed that way by a top Agostino guy that knows Krell inside and out. The 222 one box version would please as well. Really love the phantom pre. 

If you guys have any other preamp suggestions to go with the d'Agostino amp, i'm open.
I'm looking for a top notch combo under $50K to build my reference system that's why the Dartzeel will be hard to beat for the preamp part.

I want to demo the Krell Phantom & 222 models.
