Dan D'Agostino Momentum amplifier- which preamp?

For my part I feel compelled to go with the herd on this one David, having demo'd various combinations of full on D'Agostino to mixed Pre and Power, my personal preference settled on ARC Pre into D'Ago Momentum Power.

I use Coincident Statement pre with my Momentum Stereo amp, all copper cabling and the sound is fantastic through my Tannoy!

I use a Krell two box Phantom preamp with my Momentum amp with incredible results. I would think the one box version(222) would excel as well. I was actually guided to my unit by a top Agostino employee when I inquired as to what Krell preamp of recent past was really special. The Phantom has looks, ergonomics and superb sound. FWIW the dealer I bought it from suggested that the ARC Ref 5 wasn't in the same class and he's an ARC dealer. FWIW.

With D'agostino Momentum i suggest VAC Signature MK lla or Master linestage or even Statement Line Stage if budget is not a problem for you.

I'd certainly consider VTL linestages as well.  

I've compared several of the ARC Ref's to the VTL 7.5 II and III and preferred the VTL's.  The comparison was done on a friends system using Rockport Altair's - fantastic speakers by the way.
