We were doing so well until you mentioned the need for two HDMI outputs. To achieve that, you're looking at a very few receivers, the Onkyo TX-NR905 being the obvious example at about £1400.
The way round this is to use an HDMI splitter, allowing the signal to be fed to two displays - it might be much more cost-effective to spend £70 or so on a unit like
this, which will take one HDMI input and feed it to two TVs.
But bear in mind that HDMI isn't great over long cable runs - if your other TV is more than about 10m from the AV receiver you may be pushing things a bit, unless you slot in a repeater or equaliser such as those
here somewhere down the cable to boost the signal. Otherwise you may well get 'sparklies' - little glittery bits of interference on the picture - or the cliff effect, where the signal gets so weak you simply get no picture at all.
Anyway, use a splitter such as this, and you could use much more affordable receivers, which would drive the MT30s well. Obvious contenders are the Sony STR-DA5200ES and the Onkyo TX-SR875, which sell in the £800-£1000 range
