Help selecting integrated amp for ls50


Hey everyone,
its been a long time since I e posted here but it's time to upgrade my system and I need suggestions. 

Im thinking heavily of picking up the ls50s (although I've selected these without auditioning them since no shop here has demos).  I needed something small and in a white color (and yes, these factors were influenced by decor and my wife).  So if I do choose the ls50s I would also need a integrated amplifier.  I've read tons about the necessity of careful matching of room, amp and placement so I thought I'd better ask here before I pull the trigger. 

The room ithe system will be in is concrete and is about 15'x23'. It's a combined kitchen and living room no separation. There is carpeting on the living room which is 15'x13'. The speakers will be on a sliding shelf from a wall unit/ cabinet system. The shelf will allow the speaker to stick out of the cabinet. 

Budget is ideally <$1,000 for the amp but I'll likely get a used one to maximize the buck. Any help would be really appreciated!

Thanks. Those Vandys are a pair that I had not heard mention of yet. I'll investigate further. Any though from others?  Anyone else using them in a wall unit or bookshelf?
Also I'll be mainly streaming music via wifi through a SMSL Sanskrit DAC and Google Chromecast Audio, and VD via an Onix XCD-88 player. I also have Wasatch, and Mapleshade Clearview Golden Helix speaker wires to use. 
one to think about is the Creek Evo 50 esp if you find one used

highly regarded; maybe has Brit-Fi sound(??) but that would fit with your speakers and Brit-Fi is a good idea in general

The Arcam A19 is known to be a great match for the LS50.
