Zu Omen mk2 (DW+)
« on: 4 Jan 2018, 11:07 pm »
I'd like to start a thread here on the Zu Omen mk2 (Dirty Weekend + Clarity Cap upgrade). I bought these wonderful speakers and I'm curious about amplifier matching. (I'm less interested in opinions on the speakers themselves... if you own them and love them, I'm curious what you run them with... if you don't like Zu speakers, this isn't the thread for you!)

I am encouraged to start this after reading the review of them by John Richardson... they started some back-and-forth on amp matching in the comments here but then it died off.

https://parttimeaudiophile.com/2017/07/29/mini-review-zu-audio-dirty-weekend-omen-version-ii/

In particular he runs them with Decware SE84UFO2 fronted by a LTA microZOTL2 preamp, or direct from a DAC.

I am currently running them with a vintage Luxman integrated that I've had refurbished and recapped, the L-450. I've also run them with a Line Magnetic 518ia. I prefer the Luxman in fact, but I'm still seeking to maximize the resolution on the speakers, retaining the "alive" sound while also coaxing soundstage holography and midrange magic.

Some amp thoughts I've curious about with the Zu: Eastern Electric minimax or M520; a First watt; someone here told me a Naim integrated sounded amazing; a chip amp (47 labs or Clones); Decware SE84UFO2 with and without a preamp; a solid state class A integrated

Any takers?

Cheers.

I used to run my omen mk1 with PX24 monoblocks or 300B but I now use a Sony receiver STR6055 and the bass is better controlled. Valves are fine but bass control needs better damping you don't get with low output valves. I've always been a valve man and dismissed solid state until I tried the Sony.  The phono stage is damn good too.

I have no experience with Zu but have been using the Digital Amplifier Company Stereo Maraschino with my Charney Audio Maestro. Detail in spades, great tonal balance, imaging, sound stage, deep controlled bass, and exceptional mid-range. Well worth the try with a high eff speaker.

I've got Zu Dirty Weekend's and a Line Magnetic 218ia. Superb dynamics, powerful controlled bass with good synergy on all fronts.

I have Zu Omen original version, with upgraded caps and resistors.

I used it with Dared 2a3, then with Larry Moore 300b. As somebody mentioned before tubes have gorgeous midrange but have difficulty producing controlled bass.
At the moment I am running Zu with my custom Abacus TPA3116 - midrange comparable to that of 2a3 with much better bass.
Building TPA3250 and 3255 amps to see if improvements is SQ could be made.

I used tube amps for years, but went class D as the future lies there, in my opinion. Besides, here in the South the tube amplifier is inconvenient in the summer ;)

I use my own John Broskie's Aikido preamp as well as Aikido Phono preamp.

Thanks guys for your input. I love hearing success stories. I think these speakers are pretty amazing, especially for the price. I'm enjoying them. I have never heard Class D or Chip Amps, I'm curious to give them a try!

I have had a few different class D amps and the DAC (Digital Audio Company) amps have the most “real” sound of them all. Other amps had a slight grain to the high end and sounded thin. The DAC amps are very clean and clear up top with a very natural sounding (more meat on the bones) presentation. I was expecting to not like the DAC amp but now I’m a believer!
