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.

Paul,

From the emails we've exchanged and from reading a lot on the forums, I'd love to pick up an F3 when one comes available. The Pass built one is out of my budget at the moment, but hopefully a rawson built clone will come up soon... it seems like people are really holding on to them these days since Tim retired.

Phil,

I think you are absolutely right. The stock Dynaco is a good recommendation for someone wanting to get into tubes inexpensively with these speakers, but not really an 'advanced' piece.

It does sound nice--fat warm ans as you noted euphonic, but it was putting me to sleep... literally. I was falling asleep an hour and a half earlier than usual with that amp.

I will say this though--listening to a couple other good amplifiers reminds me of how good the Firstwatt is and makes me realize I'll really need to step up to something 'great' to better it... tubes would be nice, but the experimenting I've done has taken away some of my feeling of urgency to move to something else and the thinking that my pairing is less than optimal.
We need more pics. To those who have received their souls- bust out with some pixels. Are you liking the cosmic carbon? I just got off the phone with Sean, since mine haven't shipped I am still talking color options, so I would love to see some in situ shots. Thanks
Did you see the ones in my audigon system? I'm a crappy photographer, but I'll ask the wife to take some shortly if you want so more.

I'm keeping my F1 and upgrading it to an F1J. Hopefully this will be the ultimate for me.

I've resolved to sell the Dynaco-I don't prefer it to the Firstwatt or Virtue. Its very nice, but not what I want.

As for the Virtue TWO.2, I'm going to upgrade my enthusiasm over it. Until tonight I'd been using the integrated as a poweramp. Today I finally swapped the jumpers to bypass the volume pot (i.e. make it a power amp) and its REALLY kicking ass with the Soul Superflys. MUCH ballsier presentation--it finally SOUNDS more powerful to my ears. Very detailed, warm, engaging sound. I like what I'm hearing. This unit doesn't belong to me and is a loaner through another audio forum (but I'm tempted to make it mine depending on how the F1j fares).

Whether I buy it or not, for those out there with a tubed preamp, I'll give this an absolute recommendation for the Superflys. This thing is kicking some serious butt!
I changed a couple of variables in my system and gave the Dynaco another shot and I'm actually liking it a good bit more. I kept my reference ICs on my pre1 to F1/TWO.2 and threw on a "magwire" IC between my pre's second outs and the Dynaco and a pair silver speaker cables--(Grover SR, an old version I still have on hand) between the Dynaco and Souls and I've gotta say, its sounding great.

More balanced, lush and musical and very dramatic sound. I think I will keep this sucker as its matted to my extra cables anyway. Whether you believe some in cables or not or just consider them tone controls, this was a move towards what I was looking for in many respects. Interestingly I think I prefer how my digital sounds with my SS amps and analog with the tubes.

I'm very excited to have the option of switching between what I consider very good solid state and nice sounding tubes at will and without cluttering my living room.

As Phil stated in previous posts, the Superflys let you REALLY see the difference between different amplifier's presentations. That said, this will probably conclude my amp rolling for at least a little bit. I'll report back when I get the JFETs in my F1 though.

Time to go enjoy some music.
Gopher:

I mentioned to you on 7/06/2010 about upgrading your F1 to the F1J. I've read here since that you are going to do so. One potentially huge difference (problem?) for you, especially if you are using a tube pre: the input impedance for the F1 is 100K ohms single-ended and the F1J is 15K ohms (note at www.firstwatt.com under products it says 100K and 10K respectively, clicking on F1J it says 15K single-ended). Rule of thumb (from conrad-johnson): pre output impedance < 10% x amp input impedance, i.e. your pre must be less than 1500 ohms or you will probably lose some of the low-end frequency. You might want to send an email to Nelson Pass at nelson@passlabs.com and discuss this, especially if your pre has an output impedance greater than 1500. I'm anxious to hear what you think of the Soul/F1J combo, if and when you finally upgrade.
