I am currently running CDX2/272/XPS2/300 nonDR. My senior bombarded me with his theory on source & keep suggesting me to swap 272/XPS2 with 282 in the future.
Could anyone give me a valid reason for the change counting the 272 was a newly bought piece (Nov/2020) and I have no complaint on current set up !
As an analogue pre-amp the NAC282 should likely eclipse the NAC-N272 in same role, especially when you up the PSU ante. However, bear in mind you’ll need a streamer (at least an NDX2) and also a power supply (at least a Hicap) for the NAC282.
If you have no complaint you might just enjoy your music. On the other hand I think if you were to hear a 282/HC through your NAP 300 your mind would be pretty quickly made up!
If you prefer your CD player then a 282 makes sense and through your 300 will be superb. You can also move the XPS on to the CDX2 which will improve your source too.
This leaves you without a streamer which is an additional expense and depends on how good you want it to be.
If you are happy to forgo CD’s then an NDX2 with your existing XPS would be a good choice.
I agree with @trickydickie . I would just add if you like both CDs and streaming, you could add the XPS to the NDX2 and use the CDX2 as transport with the DAC of the NDX2 (it should be better).
Bear in mind that this would only work if your CDX2 is the later version with the digital output.
It’s worth asking yourself whether you actually need a CD player when you have a good streamer.
The 272 is an excellent box. The 282 isn’t hugely ahead and it may be that your friend is simply justifying their own choice. Remember that there is always something better - you don’t have to have it.
