My answer is not going to help because I went in a different direction and I'm now using a 2 watt amp with a pair of Sonist Concerto 4's.When I sold the Alon 4's, I bought reference 3A De Capo's and then Sonist Concerto 2's and now Sonist Concerto 4's.I'm retiring next month so these will be my last! But I have no desire to change speakers as these were the sound I was after.Good Luck, TISH
