Ideal amp for B&W matrix 800


Hello everyone, I am looking for a great amp for my B&W MATRIX 800 speakers (the tall ones with the angular shaped bass cabinets, not the nautilus ones!).
I have a tight budget and live in Belgium.
My cd is Accuphase 500, preamp is solid state, no tone controls magnum Mp330.
I am looking for a 3d soundstage with lots of depth and emotional music playing. I therefore think of class A amps.
Hence... older krells? Tube amps would be a bad match as the speakers each have two 12 inch woofers. They are 4Ohms, with an impedance dip to 3 ohms in 100-200 Hz region. they are 93 dB/1W sensitivity though...
I could spend about 2000 euro but would prefer around 1000-1500 so I have budget for an accuphase preamp for phono (a c-280 or so). Would appreciate your input guys!
At the moment I localised a krell KSA-100 MKii for 850 e, a Krell KSA-200 S for 1750 e, a Krell FPB for 2000 e...
Or a Pass X250 for 2400 e.... Other suggestions are very welcomen these or just the ones that I found on sale some place now... I have never heard any of these amps...

@tattooedtrackman  Nice to hear u have great results with the fpb600, what pre and source are you using? What about cabling? I use audioquest wild wood speaker cables
@blue sky walker. I am running an ARC Ref 6 pre amp and a Rega ISIS Cdp. Speaker Cables are all StraightWire Crescendo as well as XLR ics. Power Cords are Shunyata King Cobras. 
Hi @tattooedtrackman, thx for the reply, I did not get any mail notification of a reply in my thread, sorry.
I am just now discovering the importance of good power cables...

Ideal amp for B&W matrix 800

Between 55hz to 250hz (most of the bass) they have a load (impedance plus - phase angle) that demands current from an amp to get the best out of them. Amps that can almost double their 8ohm wattage to 4ohm and again to 2ohms.

But because they are 94db efficient they don’t need a lot of watts an amp of 100watts into 8ohms will do, even the very old 25watt at 8ohm Mark Levinson ML2 monoblocks will sound great to a certain level because they can keep doubling wattage down to to 1ohm!!! https://img.ukaudiomart.com/uploads/large/2229206-mark-levinson-ml2.jpg

Amps today that will be nice would be the Gryphon Diablo Integrateds 120 or the 300, they can do the doubling act. Also the D’Agostino’s , Parasound John Curl Halo’s, Krell’s these are all bi-polar output that can do big current down to 2ohms.

@georgehifi  thx for the reply, I use Rowland 725 amps now and looking for good powercords for them as they matter a lot.
they do not have 2 ohm specs though... would they be less then optimal?
