I would plan a Full Stereo system in my Media Room.
Headphones are good but sometimes would change.
It must not really Expensiv but good enough.Good sounding for sure.
I have see the not bad denon pma 520ae Amp or the Yamaha S501 and the Denon Pma 800NE
Speakers was focused the Elac debut 6.2 who i find not bad.
My Dac is a Singxer Sda 2 C.And would go to connect via Rca.
Or when possible a full Stereo amp with Balance input where nice to.
The Singxer Sda 2 c have a Balacend output.
Some advice for the three amps or another amp from you where be nicely.
EDIT: I have take a look for Speakers.Would put them on the Wall when is possible.
Not easy, here the List:
Elac debut B6.2
Dali Alteco 1
Dali Oberon 1
Have listen today the Yamaha S501 with one from the Elac F6 series,was not really spectacular in my ears.
