My gate swings both ways. I run ATC active and passive....and love them all!
ATC 50 and 40 actives, ATC SCM 20 and 7. Why not? I feel as if the only 'fault' ATC transducers have, is an unforgiving nature towards everything in front of them. They sometimes scream "you lied to me, you said you would feed me only the cleanest signal and recordings".
Every system change I make is reflected truthfully, for better or worse. Sound Anchor stands with Herbies Fat Dots under ATC 20s, thumbs up. Improved cabling on ATC 50 actives, thumbs up.
Expensive is so subjective. I foresee keeping my loom of ATC transducers for a very long time.
