Hello, i am a Naim fan. Driving the system with a NAC 272 with 555 ps with 2 Jeff Rowland model 6 vintage mono amps. Wired it all with Chord super array. I tried a Hegel p30 from a friend and it wins out the preamp of the NAC272. I reed people saying that the preamp performance of the NAC272 hangs between the NAC282 - 252. I want too upgrade to a NDS with the 555dr so need a good preamp. The sound of the Hegel p30 impressed me very much. Very tubelike natural sound and with good dynamics en bass. It has the musicality like Naim gear. They are also a lot cheaper than the Naim combo’s. Does somebody have experience to help me compare? Because i do not have a friend where i can borrow a Naim preamp to try it at home and do a long period of listening.
