I concur on the NS5000. I choose it over Vivid, Magico, and KEF Blade. Though the Blade would have made me equally happy.
I use a CODA #16 ($9k used) but did consider the Schitt TYR and Benchmark AHB2 for them. The monos were under consideration to use my great (but very short) FrontRow speaker cables. The CODA #16 is amazing with the NS5000 with WyWire Diamond speaker cables.
One way to save some cash maybe is to use the new Schitt Moljiner 3 preamp. The M3 is a great Class A preamp and cost $1200. I now have 3 great preamps, the Benchmark LA4, Holo Serene, and the M3. All 3 are also in the affordable side of things.
The M3 is much better than the Freya+ (sold).
A used Magtech amp from Sanders Sound Systems ($4k) is another of my very high recommendations. I use it with the Magnepan LRS+ and it is stunning. I have not tried it with the NS5000 but should very good. Maybe not as Class A sweet as the CODA #16. The only amp that was as good on the LRS+ was the CODA #16.
