I was very impressed by HiFi+ editor Roy Gregory while attending the System Setup & Tuning seminar at the RMAF 2008. The information regarding electrical power and system component isolation I learned during his seminar and in the Nordost room from Lars Kristensen were very en-lighting. I've started addressing these issues in my system and have been rewarded with amazing results already. I've added Nordost pulsar points under my preamp and digital source components and hearing tighter bass and overall more cohesion and articulation. I've ordered a Quantum QX-4 for my preamp and can't wait to hear the results.
Many thanks to Roy Gregory and Lars Kristensen.
