The real "Passive" monitor controller.

I had tech problems with my Central Station and sent in for service. With the CS out of the chain, I routed my Convertor to my Driverack PA. The difference was incredible. I realized my sound had been colored and veiled. I ordered the M3PH. I am not hearing coloration and the D to A output is torally transparent. The stepped attenuators are mostly responsible along with American made, no frills construction.

Great gear, *great* support

Just a fantastic piece of gear, perfectly transparent, excellent stereo separation down to very low volumes.. Perfect for my application.

As an aside, I had a question about routing unbalanced signals through the M3PH, and sent it by email to Coleman. Within 5 minutes, Glen Coleman himself called me to discuss the options :) ... a super nice guy who was happy and willing to take time to talk electrical/audio engineering with a hobbyist. Now *that* is customer support!!

Excellent piece of equipment indeed!

Far exceeded my expectations. I owned a Presonus Central Station before this and there is really no comparison. The stepped attenuator is the best feature as it provides perfect stereo imaging though out all settings. There was a good degree of stereo shift at low volumes with my central station. The attenuator is also great because you can keep precise track of your monitoring volume. Sound quality is fantastic. I don't hear it at all, as the central station degraded my sound slightly.
The Headphone amp in this thing is amazing. Its the best headphone amp I ever heard.
My only complaint (if it even is one) - I would have liked to have seen a different layout for the mute/mono controls. That aside, this piece is well worth its hefty price. (ps, If i was rating the central station compared to this, the CS would only get 2.5 stars).
