Audio Research Amp/Pre matching


It is time to once again upgrade(change) my system. Looking at building a new system around a ARC VT100 amp, question is which ARC pre amp is a good match for this amp. And I am certain that a REF 5 would sound great but I mean a older good value for the money ARC pre that is a good blend with this amp.
Thank you for your suggestions

I had an Audio Research VT100 matched with an Audio Research LS 25 preamp in a previous system and it was an excellent match.
Go with a REF3 or and LS26, I have the LS26 and would like to upgrade to the REF3 when the $$$ matches the dream. Also
ARC is doing some upgrades to the REF3 , I assume the knowledge they gained in producing the REF5 has revealed some circuitry/components that they can retrofit. A very nice gesture that ALL manufactures should offer.
Thanks for the input. Ref 3 is a still a bit too expensive for me right now. Was thinking more LS 25. What about an LS 15? is it worth looking at? I can always upgrade later but want to get a amp/pre combo now that will get me into the ARC line up. Thanks again!
I use an LS 25 with a VT130SE. The combo works very well for me, but not everyone loves the LS-25. It's at the dryish end of the ARC tonal spectrum. Pretty neutral to my ear, but not particularly satisfying for the listener with a full-on tube jones.

FWIW
