Parasound Halo Integrated vs Yamaha AS2100

As general rule I've always thought the heavier the amp The better. And the wattage on them at 4 ohms are fairly close. The Yamaha look is pretty retro and inviting. I like the built in DAC on the parasound. I do listen to some digital audio so that has been a reason for my liking the parasound. But there is just something about the Yamaha that makes me think it might be the better choice. The warmth aspect for the vinyl definitely makes me lean towards the Yamaha. Not that I've made my mind up on the ML Motion 40 I'd like for what I get to be a good pair for them if I decide to go that direction on the speakers. Also like paradigm monitor series and monitor audio bronze or silver series. So many good choices out there. Overwhelming at times. 

I heard the A-S 3000 driving a pair of KEF Blades in Berlin , all I would ever need on Acoustic Music !

What DAC or preamp would be a good fit with the Yamaha? 

The Yamaha is an integrated amp you don't need a preamp with it.

It doesn't have digital inputs for streaming devices etc for when not using vinyl.
