benleey, I see from viewing the posts, you owned the Sequel IIs then upgraded to the new Summit. I owned the SL3 for 8 years and just upgraded to the Odyssey. Therefore your upgrade was more vast bypassing 2 versions. What can you tell me about the new Summit and how it sounds compared to the Sequel IIs, and did you ever hear the SL3 or Odyssey and compared them? Another question: Living in Asia with a different power supply, does Martin Logan supply a different AC to DC conveter or does the dealer change them? Or maybe a better question: can the dealer change them?
