Which amp would you go with

Ok the room is 13 ft wide.  Listening area is 10ft from speakers 2 ch system. The floorstanders I will be running are Tannoy XT6F.  The source is Oppo 105 as preamp.  Pretty simple setup.  The only thing not purchased yet is Amp and/or sub (if needed).  Around $1000 give or take is the budget. The short list in order of preference is.

and the fallback option


The smart buy is an integrated. Variable out is no substitute for a pre-amp. Separates make no sense below the mega-buck cost no object level. Which you ain't. No purchase is forever. A separate power amp ties you into a weak position by limiting future options. The right integrated will sound better now, and pay big dividends later when you go to upgrade. Which you will.
Musical Fidelity like most suggest.
I had the Musical Fidelity M3 which is basically the
M2si and it's a fine amp. The build quality on it is
excellent and it's more powerful than the numbers
would suggest. 
Well I am going to have to chime in on this one as I have the Vincent SV-500.

I have had it for about a little over half a year so far and love it. Connected to Martin Logan Motion 40’s and since they are 4 ohm speakers, the Vincent (according to their specs) should be pushing close to 80 wpc. Also connected to it is a Questyle DAC CMA 400i, Denon Universal Bluray Player for CD playback and a Denon dpf-300 TT with a SimAudio 110lp v2, Denon Cassette Deck.

All I can say is that I am loving everything. When I first got it I was afraid it would not have enough power for Logan’s but wow, I do not even need to turn up the volume very high to get good music to my ears.

I really wanted the big brother, SV-237MK but it was out of my budget and so took a chance on the SV-500.

I recently added a Isotek Evo3 Sirius Conditioner and High Fidelity Cables MC-0.5 to the system plus Audioquest Power Cables to the Vincent and Dac. I feel it has definitely added some impact overall, deeper bass and bigger sound-stage (holy crap, am I talking audiophile language now, haha).

Anyways, I can vouch for this Integrated but I am sure the other one’s you are considering are awesome too. I do not feel the need to do any tube rolling as I am quite content with my setup so far.

The only other thing I want to upgrade eventually is my TT and upgrade to a dedicated CD Player or Transport.

So that has been my experience.
