NAD C320BEE all the way Can be got for £100 - £150 and still a cracking amp 8)
Not sure about that... The 8000A was made to a far higher spec internally than the budget NAD. If the Audiolab is cutting out, I can imagine the NAD doing the same. The best way to do this down the NAD route is to get a C270/272/275 power amp to add on to your 8000A, those are pretty gutsy.
If you need the power, the Roksans are very good amps. A little clinical sounding though, so may not match the Monitor Audios terribly well. Then again you could go with some amps which have better power supplies to gain back a bit of warmth in the sound, Arcam Alpha 10, Musical Fidelity A3 etc, all are about £300. I've personally used an A3 to power my ProAcs at the 2 O'clock level when I was painting the house last week. Amp was barely even warm when I got in! I know the Arcam to be built equally well and has a nice musicality and warmth to it.
Infact, I just remember I owned an 8000A a few years ago. Sound-wise it's very similar to the Roksan, so if you like the sound the Audiolab puts out, the Roksan will be very similar if you want to stick to that sound, just with more power.
