To my surprise, there is little to no subsonic pumping. Much like the Clavis. Or maybe a little more. But clearly different from the Atlas. The woofers are more engaged, more vibrations, changing from Clavis to Titan - but this fits what I hear, it is fast vibrations, not pumping.
Sonically the Titan is a clear step up from the Clavis (today, also) with wider, deeper, better detail, better e g on female voices (R L Jones: Evening..). On Pink Floyd’s Echoes, the soundscape is now almost as large as with the Atlas, although still a bit more harsh, less natural, with some sibilants (I could cure some of it through adjustments).
I had expected a gradient, according to resonance theory. The Clavis should pump least, the Titan some, and the Atlas most.
But the results - so far - are more one of a kind. The Atlas pumps, the others don’t. This makes me suspect suspension wear or some other non-optimal condition in the Atlas. Yet I was surprised to find no signs of pumping with the Titan - since this has been used maybe 500-800 hours longer than the Atlas, so if suspension slack, wear and tear, is the culprit, it should show up there. But no.
