Marchand Active Crossover reviewed with SS3602 Discrete Op Amp Upgrade.

I finally received the discrete op amps yesterday and installed them in my Marchand Crossover (XM44 3-way)…WOW!

I must say that the improvement offered over the standard OPA2134 is not trivial. Extended highs, removal of grain, more smoothness and (especially) inner detail are definitely on the table. I would presume that this is because of the lower overall noise floor as compared to the relatively noisy stock op amps. There is a real richness to the music now as well as some added sparkle.

I have written a small review on Canuck Audio Mart.

The SS3602’s Installed in the Marchand Crossover

Right now, my Marchand Crossover is a 3 channel with Bass, Midbass, and Mids/Highs (they are passively crossed over at the drivers with a 1st order), but when I switch it to Midbass, Mids, and Highs with the sub using its own crossover, I will likely order 4 more from ya. Thanks again,
and have a great day!
