Anyone listen to Zu Audio's Definition Mk3?

Alright... I swapped 'em.

The amp is warming up now... I guess I'll see how things sound when my son conks off to bed and I can turn on some tunes.

Well, I made the change and I think I perceive a difference. Seems like the stage is a bit wider and more open with images being a little better defined... maybe I'm imagining it, but I feel like I'm usually a little more emotionally stirred.

Gopher, thanks for the info on how the upgraded drivers were to be placed (I did not have instructions when I did it several weeks ago - I put a matched pair in each speaker). Just made the change tonight and it definitely better defines the images in my Omen Defs. I don't notice any other changes, but it was a worthwhile 15 minutes.

Cool to hear I'm not alone on the image focusing. I did some listening last night, but it was pretty passive while I read.

Things do seem a bit more dialed in though and I think I can attribute the lack of pull from immediately after the change to a combination of my general mood at the time and things needing to settle again after being disturbed.

an update on Def4 amps. One of my Quads went down and so I picked up an Almarro 318B here on the 'gon. I found it a poor match with Zu Definitions. The amp wasn't strong enough in the bass and clearly favored midrange and smooth type sound. It may work with monitors better, but it was one of the worst sounding amps I've heard on Definitions *in my system.* In it's price range, the SEP Mastersound with NOS tubes was much better to my personal tastes.

just landing this afternoon is a Vac Phi Beta, KT88-based, super integrated. I am hoping it will be the cat's meow once appropriately tubed. I have owned a Vac Phi 200 before which sounded a bit SS, but didn't use Black Treasure KT88s on it (which is a large upgrade on my Quads)--the Phi Beta has a full 6sn7 linestage inside that should complement it very well.

i do reminisce quite a bit about FirstWatt- if the SIT2 was 20 watts, I'd probably still own it.
