My Review on Naim Audio XPS- 2 :
Basically, the WOW factor was not very obvious to me. After performing a simple A-B comparison (with and without XPS-2), I noticed audible details improvement on all aspects (difficult to explain, it is just like the overall presentation improved and also musically).
Built : Still Mint condition
For this amount of money, even for 2nd hand, I am abit reserved to recommend the upgrade. Maybe with DR (Discrete Regulator) upgrade, it will be more worth it!
P.S Subject to changes in opinion with more prolong listening! 🙂
