My advice is to spell advice with a "c".
Well, for the prospective system…
The Genelecs make a lot of sense.
As @djones51 mentioned:
You don’t need a DAC for Genelec the ones speakers
So the OP may be better off getting a sub than a DAC... (IMO).
You can have a nice system with any of the stuff listed in this thread. But you have severely limited your options for advancing your system
I think that the OP would end up with something that likely is fine sounding, without the hamster wheel of upgrading amps and preamps, and sources.
So it makes a lot of sense IMO to go with the fully engineered solution.
I would not worry about missing anything in terms of cobbling together preamps, amps, cables, and power supplies. The OP gets well down the road without (god know how much) waste in terms of extras to tune the system.
