An inexpensive amp/preamp/integrated for Zu bookshelf speakers


I am thinking about a small stereo system for my office and am looking at Zu bookshelf speakers. 
Since they are so efficient, I only need a small amp/integrated amp. What would you consider?
The Schiit Ragnarok looks promising at $1700. (I have the Bifrost DAC on my main system and love it).
I'll probably connect it to my PC and stream music.

Goldprintaudio, the Line Magnetic seem a bit pricier than I was hoping, though I have never gone the tube route.
Yogiboy, the odyssey looks promising, thanks!
No problem, just thought I would throw them out.  The 211 is at the same price as the Schitt you mentioned. (well I guess actually $50 more at $1750).
I would recommend something from decware. The zen triode integrated in particular. It's what I plan to get
Goldprintaudio, I was looking at the MSRP which said something like $2500  
Asianatorizzle, the decware always intrigued me, I need to do some more research...
Smrex, If I can get a used Dynamo, that would be another option.
