Integrate amp for gallo refernce 3 speakers

I've been wanting to upgrade my current amp and was wondering if anyone had any insight into which integrated amp would pair well with the Gallos. My thoughts were Musical Fidelity's A5, or the Plinius 9200 and possibly the krell 400xi.
Any other suggestions? Anyone currently running an integrated amp with their gallos that rocks their world?

Thanks in advance,

J.
