Anyone listen to Zu Audio's Definition Mk3?

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.

Keith,
I have found two excellent amps with my Def III's: Art Audio PX-25 and my recent acquisition the Coincident Frankensteins. I find the warmth of the Franks to be a perfect complement to the Nano FRD's. The Franks give up a little of the bass of the PX-25, but not much. Of course, that is in my system which is very detail oriented with the Metrum Octave DAC, the Allnic L-3000 Pre, and the Def III's.

Keith,

I'm kind of glad to read this as I ended up backing out of an Almarro 318 at the last minute, and have wondered at times what that synergy could have been with my upgraded Def 2s.

You got new Franks, Morgan? Awesome! Wish I were on your coast to hear that rig of yours.

It seems like you're liking that Metrum as well... very cool.

Yes the Metrum is quite nice. I do have an AP-2 for the Metrum but I'm waiting for a replacement Metrum as the Coax went out on mine........

But yes, loving the Franks and it would be great to compare our two systems.....211's vs 300's!

Not to divert the thread, but those of you who use 300b amps, should check out the Takatsuki 300b tubes that are made in Japan. Pricey, but amazing.

One other comment based on Phil's obervation about break-in. . . . in my experience, the Def 4s continue to evolve in a positive direction for months . . . even though they undergo prolonged factory break-in before shipping.
