hi james, welcome to zerogain, nice to see new faces
dont forget to put some pictures up in the 'sticky' threads.
I had a pair of living voice avatar speakers, and a friend had a moon cdp. It sounded great.
Sounds like you have 2-3k to throw at it?
My reccomendation would be push-pull valve amp, kicking out somewhere in the region of 20-30watts per channel.
I really like the Canary Audio amps, they are well worth a look. They make some fabulous push-pull 300b amps, they sound fantastic.. Kevin rates them too (mr living voice).

Be careful to ensure voltage conversion is possible with US imports, and of course consider freight and import duty.
Also very good, you may find an Ear/Yoshino amp fitting the bill. Ear make some great sounding amps.
My amp sounds fantastic on Living Voice speakers, despite being single ended 300b. It is a 'glasshouse' by hifi collective. I know nick doesnt plan on making any more. Last time I spoke to him about these, he had 'one' left - and that was months ago. You may be shit out of luck lol... It's a fabulous amp, and can hold up to anythign I've heard in the 2-3k valve amp park.
Other kits that are great - check out brian's site -

There are a few things that people just dont realize about kits -
1) most places will build them for you for a couple of hundred quid
2) OF COURSE they sound as good as something commercially costing 2-3 times as much. There is no retail, distributor mark up, and they use point to point wiring, a great schematic and really high quality parts. What's not to like?
3) Once you own a good kit, your eyes/view on expensive commercial offerings will change, and change drastically.
So there you have it, I'd personally get a kit made up for me, and a damn fine one too. If I couldnt do that, I'd buy something used in the valve world and resign myself to the fact that the used capacitors and resistors may need changing soon and further expense will probably come.
NB
I think the Lavardin sounds pretty good. You should ask Kevin if he thinks it sounds as good on his speakers as a good valve amp though...
