I don't have any experience with the amps your looking at but have just
spent 7 hours auditioning three combinations of speakers that you are
interested in. The first speakers I tried were the Monitor Audio Radius
R270HD fronts, R225Hd centre, R90HD surrounds and RX-W-12 sub. I Liked
this set-up. It had strong vocals, great bass and controlled treble. The
second speakers were the B&W MT-30. The extra detail &
separation over the Monitor Audio's was obvious straight away, but some
of the warmth & resonance in speech was missing. Everyone spoke a
pitch or two higher. The last set-up consisted of the B&W MT-1's
& the Monitor Audio RX-W-12. A bit of a mix & match. This was
the system the experienced sales team had recommended, & I think
they were right. The warmth/presence (not coloured) was back and mixed
with the detail delivered from the MT-1's, sounded amazing. I thought
this was the best solution for me. You must demo everything you intend
to buy or costly mistakes can occur. This is the advice I've always been
given and it held true for me. The system I've now bought is unlikely to be reviewed in magazines such as this as manufacturers aren't keen on promoting other peoples gear. Try this set-up with your choice of amp and you could be a very happy chappy.
