We have added ATC-SCM100ASL as our main monitor around April 2009. They are full size and very heavy monitor. The first day when we replaced our previous Manley ML-10, the ATC was sounded so horrible that we wanted to throw it out from the window. We have stopped our mastering session for a week also. After 3 months of burn-in, fortunately the sound is becoming better and better. The ATC-SCM100ASL is good for work. It is easily shown all problems of different recordings. It can handles large range of SPL (from low to very high SPL). I am surprised how good they sound from high resolution digital audio and classical music, but they are not for most of today hyper-compressed pop tunes.

The Manley ML10 is a legendary loudspeaker. Al Schmitt mixes all Diana Krall albums with it, and Doug Sax (TML)was the inventor/designer of this Tannoy (coaxial horn tweeter+10″ woofer) / Manley Carbinet hybrid. My head still keep having Doug Sax comments on “Don’t sell these speaker!!” Since we don’t master with more than 1 pair of monitor, we set it up on another corner in the mastering room, connected with the Sony PCM-9000 Master Recorder (XRCD recorder), and the latest MetricHalo ULN-8 (SonicStudio 305). As you can see from the photo, we have a Primacoustic – Recoil Stabilizer under the ML10. It works very well, especially with not so ideal supporting platform (e.g. shelf)

BTW, if anyone knows where I can get the Sony “MSD–1200″ – MO Disc for the PCM-9000 Master Recorder, please let me know. We want to get some blank disc.
