Anyone listen to Zu Audio's Definition Mk3?

Phil,
Very good advice for those who may be interested in the 300b amplifier route(strong,over built power supplies and transformers). In terms of the output tube for superior bass weight,impact as well as control/firmness and articulation= Sophia Royal Princess and the Takatsuki -TA 300b. these two do it all from bass to treble,they`re superb but very expensive unfortunately(they do deliver the performance!).Both are supreme, Takatsuki just a bit better.

SpiritofMusic, when do you expect your Def4's and when do you plan to audition the Audion or Berning amps?

Glory, thanks for the clarification...if I was on Computeraudiophile, I'd have picked it up immediately, but since so few here seem to use computer audio (yet) the acronyms went right over my head.

Thank you to all who have answered my questions...lots to digest. I plan to work on some basics, some amp stands (Atma's are setting on a cherry shelf which is laying flat on a tile floor, and speaker positioning as I wait for my Def4's (probably a month or so).

After I optimize what I have and enjoy/get familiar with the Def4's for awhile, I will inquire about auditioning an Audion or Sophia 845 based SET. This seems to be a fundamental question that begs an answer...will the right SET do it for me or am I a hopeless OTL lover? If SET is it, I probably won't sell my Atma-Sphere's...just really loved what they've done for my musical enjoyment in so many different systems. I'll keep them as my 2nd set of amps should I desire a "change up" from time to time...unless, of course, the SET experience is truly paradigm-shifting I suppose. Never know till you try.

As some of you receive your Def4's, please keep posting here...we've got some great commentary already from GSM, Cobra, and others. It'd be a shame if others didn't share their thoughts/experiences with the Def4's. Besides...I'm stuck getting my fix vicariously for at least a month...help an audiophool out, would ya?!! :-)

Beautiful dogs you have GB.

The Pic of Samson sleeping is the 845 in action and the outside pic of the dogs alert and ready for action is the OTL in action.

Sorry I just had to write that. All in fun boys and girls.
