Just joining in a bit late here. I have the Naim Nait 5SI and after a couple of months of break-in I find the amp to be very neutral and actually quite intoxicating after some time of listening, you just get carried away with the music and no longer caught up in constant evaluation of your sound system, etc. There is no such thing as the perfect system unless you have tons and tons of money to burn and hours to waste your life away. The pursuit of the high-end can be a horrible addiction never admitted to by those that pursue it. At some point you need only to sit back and enjoy your recordings accordingly. My system: Q-Acoustics Concept 40 floorstanders, NACA A5 Cables, Nain Naiit 5SI, Arcam IR-DAC, Kimber Silver Streak rca's, Marantz CD6005, Kimber Hero rca's, isoblocks, vibrapods, acoustic wall mounted panels. I find Arcam gear to be o.k. for the money but it does not grab my attention, where as NAD to me has no signature to its sound, to me sounds lifeless and boring. For intergrateds and best bang for the buck to me: Naim, Rega and Bryston. I just happen to own Naim and quite happy with my system..everyone has different ears, enjoy!
