I have the similar but larger D900's. I found that positioning the speakers correctly and damping the room reflections had a much bigger influence on the sound than changing the amplifier. After damping the room reflections with wall hangings or whatever suits you, carefully adjust the distance of the speakers from the back wall to balance the bass with the midrange. Removing the foam plugs from the ports may also be required. Also toe the speakers in towards the listening position. I suspect that until you take care of this no amplifier will sound right.
I have taken the extreme position of having curtains round three sides of the room. With Musical Fidelity 308CR amplifiers and preamps the sound is pretty good.
A good surround affect can be achieved with relatively inexpensive amplification for the rear channels, so I would focus on the best two channel amplifier I could find.
I have never found bi-wiring or exotic cables to make any difference, and most valve amplifiers just sound cheesy to me. However if you are up to getting the additional equipment, the Tannoys respond amazingly to bi-amplification.
