Anyone listen to Zu Audio's Definition Mk3?

Charles, my UK Zu dealer concurs that Dueland CAST Cu capacitors on the tweeter are likely to be a fruitful avenue re upgrading the 4s to make the top end sweeter and more extended, and importantly, better suited to a wider variety of amps, be they SS, SET 845 or OTL.
Just waiting on Sean to inform of the capacitance value before possibly going ahead with the change.
I'm reasonably confident this may tame some of the glassiness apparent with my Hovland Radia SS power amp, obviating the need to go tubes only.
If it presents a level playing field and is more SS amp friendly, it'll be worth the price of admission.

I'm pretty sure the caps that Zu uses are quite small and therefore less expensive, even for the Dueland.....please keep us updated:)

Spirit,
Just to be clear on this point, the Duelund CAST will not 'add' warmth,fuller body or sweetness(nor will it subtract these qualities). The CAST is honest,pure and most of all 'natural'. what ever is the instrinsic character of your components,that`s what you`ll hear.

The CAST is superbly transparent with very high resolution, its presentation is simply organic as opposed to analytical-clinical.If you really like your Hovland combo the CAST will reveal them completely. If the current tweeter capacitor is a 'bottleneck'(limiting factor) then you`re in for a special treat once it`s replaced.If the baseline quality of a system is already very good the CAST allows the full potential to shine.It won`t gloss over inherent flaws.

A friend had a HP200/Radia combination. I liked the sound of that combination with his Sonus Faber Anniversario speakers. My primary gripe had nothing to do with sound--the steps on the attenuator are too course for finding the "right" volume.

While the performance was very good, there was no mistaking the sound for that of tube gear--there was still a slightly brittle edge to the initial attack of notes, and it was lacking a little bit in low level dynamics (good tube gear is more lively at lower volumes). The "glassiness" will probably be something that cannot be erased completely. I heard that with my friend's system, but, I did not find it to be nearly as bad as with other systems I've heard. While your amplification chain may partially be the source, the biggest culprit tends to be source gear, particularly digital sources like cd players and music servers (actually a lot of CDs themselves a mastered to have that kind of sound). I hear that problem with my all-tube amplification chain when playing digital sources (particularly my music server vs. my cd player).

I have not chosen to try to "cure" that problem because that would probably mean turning the sound to mush (something one can easily do with choice of tube gear).

Charles1dad,

Thanks for the interesting discussion of the Dueland components. I can easily experiment with my own system (crossover for each speaker is in three external boxes). Do you have any experience with their inductors?

The Duelund inductors have been on my mind as something to do down the road.Per word of mouth they occupy their own superior level as do their Capacitors. There`re two versions available, CAST and waxed paper in oil(WPIO).Based on my rewarding results with the capacitors I have no reason to doubt what is said about the inductor`s performance.
