I have been using NAC-N 272 into NAP 250.2 through ATC SCM40s for about a decade now. I am very happy with this system. However, I resurrected my LP12/Lingo/Ekos/Klyde from the spare room recently, and I am once again falling in love with it all over again. Around half of my LPs sound better than Tidal streaming.
I wonder if it would be possible or indeed desirable, to use my NAC 82/HICAP/Linn K boards as a phono pre into the NAC-N 272. If this is possible please let me know how to connect it all, as I find the Hicap/82 routing most confusing. I do not want to spend much on a solution to this problem. Maybe a good interconnect or two.
I suppose another approach if you’re enjoying vinyl again could be to use the 82, with Hicap, as the main preamp into the 250.2. You could then use the 272 just as a Streamer / DAC and use its Line level output into one of the 82 inputs ?
I think you have a line out phono on the 272. If you use this then the volume control on the 272 should be unusable. Connect the line out phono to an 82 input. Connect the 82 to your 250. Make sure you turn the 82 volume control to minimum before switching on.
You really don’t need two preamps (or control amps, as Naim rather quaintly call them).
So keep whichever you prefer, sell the other, and you will have ample funds to buy almost any phono preamp that you could want - although, for the life of me, I can’t imagine why you wouldn’t just fit the relevant boards to the NAC82 and be done with it.
You seem determined to pile up layers of complexity, which just isn’t necessary.
Simplify your system by selling what you don’t need. You’ll have some money in your pocket (to buy LPs, CDs, speed or whatever) and a much simpler signal path, thus better sound.
I would sell the 272 and use the cash to buy a separate streamer to use with your 82. If you’re happy with the old streaming platform a used NDX would be cheap. Sale of the 272 should give you more than enough to fund one.
