Had an opportunity recently to listen to the Thrax Dionysos in our system for a couple wks. Brought beautiful crystalline clarity in upper frequencies, very fast transient responses throughout. Nice boost/balance to mid-bass frequencies. Definitely hearing subtleties that I've not yet heard in reference recordings I've used for yrs. However, don't feel it has particularly great holographic imaging, in say comparison to the Atma-Sphere MP1/MK3.3 that we also auditioned recently, although the Dionysos is certainly quieter w/ blacker backgrounds. Dionysos also comes across a bit more forward presentation. Biggest issue I dealt with was attenuation. Volume control is not subtle - in fact 0-1 is a quantum leap, and realistically could not bring it past 3 w/o bringing pictures down from the wall. Not sure what's up with this, but perhaps others w/ Thrax experience could enlighten me?
