In the last 6months I sifted through most of the Naim forum appends on NDX2 vs ND5xs2, and came to the conclusion that there is concensus from those who have compared the two:
- naked NDX2 sounds better than naked ND5xs2
- ND5xs2/nDAC sounds better than NDX2
- NDX2/XPSDR sounds similar to ND5xs2/nDAC
- ND5xs2/nDAC/XPSDR sounds better than NDX2/XPSDR
- ND5xs2/nDAC/PS555DR sounds better than NDX2/XPSDR
- ND5xs2/nDAC/PS555DR sounds better than NDX2/PS555DR
- ND5xs2/nDAC/PS555DR sounds similar to NDX2/nDAC/PS555DR
I play guitar in a jazz band 3-4 times per month.
So I purchased the ND5xs2 to go with my existing Core/nDAC/PS555DR and am very well pleased with the foot tapping musicality of the ND5xs2/nDAC/PS555DR.
