Zu Soul Superfly

I just ordered a pair of the new Zu speakers on a whim. I was going to wait for information, but the fact that they threw in the free superfly upgrades to the first 30 people got me.

From a similar thread it sounds like some of you guys have heard the speaker despite information only being released today. I'm wondering what you can share about it?

Also, I am really hoping it works with a Firstwatt F1 amplifier. Can anyone comment as to that? I know the Druid's and Essences worked OK.
>>You need 40-50W minimum.<<

I recently had another experience that undermines any notion of a hard-and-fast rule about minimum power requirements for Zu speakers. Again, for the record, while I understand the enthusiasm some people, including Sean Casey and Adam DeCaria, have for the sound of 2w 45 SET amps (they've brought a Yamamoto to my own systems to try to convince me of it's viability as a match), flea power isn't sufficient for me. Some people will be thrilled with sub-ten-watts amplifiers on 101 db/w/m Zu speakers. However, I use 25w SET on both my Zu systems, 845 in one case and 300B PSET in another, in an open plan house where rooms aren't fully bounded. One room is 20' x 14' x 8.5'. The other is 22' x 12' x 10'.

I recently had a chance to buy a pair of NOS Quad II Jubilee mono block tube amps. The Quad II is, I've long maintained, the most SET-like push-pull tube amp. It's also only marginally more powerful than classic SET single tube designs at 15w each -- less than the big glass 845s and any number of PSET configurations. I don't need this pair of Quads; I just bought them because I wanted to own them.

The Quad II becomes marginal into low impedance speakers, but it's still quite viable into the 6ohms Zu Definition. Into 12ohms (Druid) and 16ohms (Soul) it's in its sweet spot, and a sweet spot it is. I heard a pair of Quad II on Druids a few years back, in passing, but not with a chance to listen closely. I put the current reissue as well as rehabbed originals on my list of recommended amps for Druids and Presence, particularly. But now Ive been able to listen for days on end and not only are these amps tonally beautiful, revealing and convincing but they are more than sufficient dynamically on Druids -- and by extension, Superfly. I will make a point of hearing them on Superfly soon, but I already know the answer, given my familiarity with the similarities, differences and assets between Druid 4-08 and Supefly, and the Quad II behavior into 16 ohms.

Designed in the early 1950s for it's 1953 debut, the Quad II represents Peter Walker's sense of innovation and responsibility against the backdrop of a still-struggling Britain in recovery from WWII. It's a simple circuit that wastes nothing in terms of resources. The amp was designed to be affordable in a nation still oriented to scarcity, built into a maximally-efficient packaging footprint requiring minimal sheet metal and parts. But nothing was skimped in the critical transformers.

Sure, today's legacy-informed Quad company has added 40w and 80w updates to the classic Quad II topology, bringing Tim DeParavicini to the task of improving on Peter Walker's elemental design from nearly 60 years ago. And of course they offer an excellent reissue of the original Quad II which is affordable by modern high-end standards.

I normally consider 15w below my satisfaction point for amplification with Zu speakers, but the Quad II upends that bias. Even a highly-dynamic Blu-Ray soundtrack isn't too much for it, in a room of my dimensions noted.


Interesting post as is your other post on the subject. I actually think it just is what it is and if there is a demand then other threads will thrive.

However... cracking photos. Convinced me I was right to not go for cosmic carbon but lovely to look at nevertheless.

Hi Mike,

I think it is smart to make the investment in a finish that works for you.

The percentage seems large, but is off of a small base amount.

So much less expensive than working a decorating budget for a room around a pair of speakers.

What finish did you go with?

- David.
I'd like to know what finish you went with also. I am waiting on some pics from Sean of a brown finish that an early customer requested. He indicated to me that it was only a $100 dollar upgrade. That being said I did like the cosmic gray color on the first pic in natural light. Anybody else able to provide pics?
Hi folks.

Ever since I heard the Druids I Googled loads of images and really struggled with the piano black and silver trim. It was obviously just me but I found it looked a little old fashioned. Nothing wrong with that in many ways but it just didn't do anything for me.

I fell in love with the black trim and have decided to gp for maple with black. No idea how it will look but goodness knows there's enough speakers in maple with black trim and if it looks have as good as those then I will be very happy with that.

Let's face it. Zu speakers are finished magnificently so it should be impressive.

Must admit I can't take my eyes off David's pics. They're very sexy.
