Magnepan 3.6 or 3.7 - The smart choice?


Hypothetical: If offered in excellent-mint shape used MG 3.6's for $2000 or MG 3.7's for the price of $4000 - yes $4000 not $5500-5900 - what would you do, which is the smart choice? (if the 3.7's were over $5k i wouldn't ask this.)

I lived with the 3.6 for 12 years. Have had the 3.7's for the last 7 months. The 3.6 was an outstanding speaker....but not in the same league as the 3.7. I heard a major improvement before the first song was half over. If you can buy 3.7's at $4000 a pair, buy all you can possibly get. Then sell them for $5000 and use the profits towards 20.7's. I will be trading my 3.7's for 20.7's very soon.
Got my 20.7's two months ago and I am EXTREMELY pleased with them. I spent several weeks moving them around looking for the best bass balance per Jim Smith's excellent recommendations. It was worth the effort! The new 20.7's are far superior to my old 3.6's in every single way. Very happy with this purchase.
