Integrated for Vandersteen 2ce sigII

Open baffle Needs power?????

Not the ones I have had experience with. 

2CE's do not need power contrary to all the talk out there.
They are an easy drive despite the sensitivity.
They have a first order crossover, makes it easy to drive.
Have driven mine with all sorts of amps they sounded good with everything I have thrown at them,.  From my present Line Magnetic 211IA 32w valve amp.  They even sound better to my ear with this amp in 10 W triode - go figure.
All the way up to a 500 W - 8 Ohm - 1000 W - 4 Ohm. Class D
Did the headroom improve - No!  

Not amp fussy at all, the Marantz will do fine till you get the urge to change.
They do however respond to changes in the source very well the better the source, the better they perform every time.
Spend your bucks there far more rewarding.

Given your situation, I would purchase the Vandys and use your current amp to get accustomed to the new sonics. If your amp proves a pleasing combination you might be set. Should you, down the road, desire to upgrade, you might consider purchasing an an external phonostage. One that mates well with your vinyl setup. This, in turn would would allow consideration of line level tube integrated amplifiers. 

 I think I will hold on to the marantz and see how it goes and search for a tube integrated and compare the two. It's funny how you get older and your taste change. I listed to vandys a few times in the past and didn't care for the laid back sound but now having a chance to listen to them again i really enjoyed them. So here I am completely changing audio directions. Irritates  my non audiophile wife.

I owned the 2CE Sigs for several years and for the most part ran
seperates........large Pass and PS Audio amps as my room was fairly large, but one of the last amps I had was the Audio Research VSI60 and it really made the 2s sing.......I've also heard that Music Reference's seperate tube amps have wonderful synergy w/ the 2s in particular.....

I would also consider Hegel and Parasound's new integrated amp.....at the shows they have been pretty terrific, both brands.......

There's also an exciting review in Sphile this month on an 80w integrated from Unico that I would guess would be a great fit for those speakers....

Good Luck

Stewert0722- funny you mentioned  the parasound and hegel units because I've had my eye on those two for awhile now. So....do vandys tend to have better synergy with solid state or tube amplification in your opinion? 
  This  was supposed to be my first foray into a tube/ analog waters because I was thinking the vandys would be a good fit. But after reading everyone's suggestions I could go either SS or tube and be very happy. Banging my head against the wall.lol
