First system, bought Yamaha AS-1200, wondering about what DAC to pair it with ?

So i bought the Yamaha AS-1200 brand new yesterday, they had it for 2000 euros with extended 5 years warranty. After having a look at the internals, measurments and a few reviews i decided to buy it, i basically could not do much better for 2K. They also had the m6si for 2000 brand new instead of 2800 but the internals of that amp look super cheap, low capacitance and low quality capacitors. 

Anyway, i'm looking for people who own this amp or it's bigger brother the AS-2200, and have found a DAC that goes well with it, i love tube dacs and R2R ladder dacs ! also if you are wondering, i'm pairing it with dynaudio evoke 30 or proac d8. 

Also, i'm planning to add a tube preamp in the future like the sparkos gemini, if you have any suggestions about a tube preamp that you think would be as good as the sparkos gemini i'd be glad to hear it !
