I have the rcd-1072 cdp to rsp-1069 preamp to rmb 1075 amp.For the last few months I have tried Nordost Red Dawns and Blue Heavens.I tried Synergistic Research Kaleidoscope Phase II's.Also monster cable Ic's.None of the above did it for me.Then I tried MIT Shotgun S3's and I was not happy with them either...until I let them fully burn in and all I can say is WOW.I never knew my Rotel gear and B&W speakers could sound so good.The sound stage is amazing.Everything is just so smooth and fluid without any loss off detail and amazing punch.I know there are better IC's out there but for me the MIT IC's did it for me and I now have them running through out my system.Your likes may differ and of course it is all system dependent.Hope this helps.
