Hi all, It's been a while since I posted in this forum (hello again!), so long ago actually that my account was disabled. Anyway, I've recently got back into Hi-Fi and picked up a system which consists of the following:- Macbook Pro (Tidal/iTunes > PureMusic) > Audiolab M-DAC > Naim Nait XS (2nd gen MK1) > PMC Twenty 23 Speakers Cabling: Chord Chameleon VEE3 IC, Naim NACA5 speaker cablePSU: I have a TeddyCap PSU for the Naim XS For £350 I have the option of trading in my Nait XS and swapping it for a NAC152 XS/NAP155 XS combo. I wondered if anyone has compared the two? Considering I have a separate PSU which is effectively like a HiCap2 DR would I be getting an upgrade over my Nait XS? I have heard that a lot of the Naim Pre-Amp's are based on the same audio circuitry and the PSU is where the biggest differences are. Alternatively I could sell my M-DAC and get a Chord 2Qute DAC. Although this will have to wait until funds allow. Thanks all!
