Ha! Almost exactly what I was planning to put together. Except amp was Nord (same thing basically) and I hadn't quite settled on speakers. The RAID/NAS is a given.
My friend is a long-term builder of speakers, and has messed with endless DSPs and crazy big amps.
He knows all about driver eq, and room eq, but in the end he and I now now agree that "simple is good"...
The DSPs ended up being fiddled with and got in the way of just listening. And drinking.
For our own den, my wife wanted neat and simple, and no "wires and bits" everywhere. So I had to buy an all-in-one, but it does use Hypex nCore amps which are splendid!
