Amplification Recommendations For Magnepan .7


I am new at this and I am hoping I can get some good advice.  I listened to the Magnepan and fell in love with them.  I've been gearing up to buy them over the last three weeks.  I started reading about them online and I'm seeing that good, powerful amplification is very important to get them to really perform.  At the stereo store I know they were powered by a top flight amp.  So now I have to get an amp/preamp and DAC, integrated amp with DAC or with a separate DAC. I listen to Tidal a good deal.  

The problem is that my budget is limited to around $1200 so I don't know if that can make the cut to get something that can do the speakers justice.  I'm open to buying used.  I would be grateful for any recommendations.

Okay, so I don't think that it's really that safe to use the Aune X1S amp/dac as the preamp.  If I have to use the source (computer or phone) to control the volume I'm concerned about blowing out the speakers if not careful.  I let my 13 yo daughter play her music and she's responsible but it's too risky.

That being the case can you recommend a DAC with volume control thats not too expensive?  I would want to be able to get a wireless receiver that I can use with Tidal.  Tidal is compatible with Sonos, Bluesound, or Squeezebox.  While I'm at it, is Bluesound and Squeezebox better than Sonos and which is preferred?

I now own two amplifications:
ARC LS25/II + 100.2
and
Accuphase E-360
I will have to make a choice between them in the future (it's more a choice between separates and integrated, actually).
I already drove MG12's with the 100.2 and I liked it.
so my question is:
what about the 0.7 with the ARC 100.2 ?
and what abvout 0.7 with Accuphase E-360 ?

I've never heard 0.7's, except for a very very very short listen in a shop; in that circumstance, power amp was an Accu A30, and I liked it, but listening time was really far too short to be meaningful.
So would it go like this? Tidal on iPhone to bluesound to Aune x1s to passive preamp to Bryston amp?
This this is an old posting I realize but if anyone is still looking for a recommendation of an amp to use with the .7 Maggie's, any of the Balanced Audio Technology solid state amps are a wonderful match and hit the "sonic baseball" out of the park. The BAT amps have the current needed and are a great 4 ohm amp, just as Magnepan recommends.
