I just added the Jantzen Superior caps into my xovers on my Magnepan 1.6's and the performance went up to a new level across the board. I had previously moded them with Sonicaps, but the sound though greatly improved over the stock caps it seemed a little etchy to me on some recordings. Now the speakers sound liquidy smooth and even more detailed than before with a bigger and deeper soundstage and improved dynamics. I am very pleased with the change.
Rebuilding ESS AMT series crossover.
I've read enough here to understand that my crossover network is past due for maintenance. They are powered by a B&K Reference 200.2, and the preamp is an Onkyo SR701. I've already replaced the diaphragms and woofer (impedance matched). The speakers are an early release with there only being a single 10" woofer, and it is ported. I am hoping to find a schematic and recommendations for the C & L components. I appreciate any help since I've just discovered this resource. Thank you, Bud
