I have a pair of Martin Logan Sequel II's, which I've replaced the original esl panels with the newer SL3 esl panels. I drive them with an Aragon 4004 mk.II, which handles the Sequel's very demanding without any hint of strain. This is an excellent match for Martin Logans, not only for its superb power, but also for its excellent sonics. The Aragon 4004 mk.II can be found on the used market(they are hard to find) for under $1,000.00. Try it, you won't find a better value.
Sunfire with Martin Logans
I've got a pair of Martin Logan ReQuests and am looking for a new amp to properly power them. Everyone talks about the need for lots of current, the ability to handle loads down to/below 2 ohms and the benefits of tubes in taming a tendency toward briteness. Given all the above, it would seem that the Sunfire "load invariant" amps (basic or signature models) would be ideal matches, yet I don't seem much discussion of them here. At least not paired with Martin Logans. Does anyone out there have any experience with this pairing? Please advise.
