ZU OMEN speakers 12ohms??

Sebrof,
Yes, we received the Superfly's (Superflies?) a couple of weeks ago and love them. At first I thought the sound was a bit too forward but I think that was only in contrast to the speakers I had replaced them with, which were more recessed in sound. I'm using a NOSValves modified vintage Scott 299D Tube Integrated with 16 ohms taps and the synergy is perfect! Just the right amount of bloom with dynamics. Startling realism without losing any musicality. Only thing I regret now (although my wife is fine with it) is that they didn't make them available in walnut when we ordered them (we have the cosmic carbon finish). Could return them for an exchange I suppose but they are too difficult to unplug now. Also, I highly recommend the Zu Mission cables with them.

2nd day with the Omens driven by a Sophia Baby Amp (10wpc). 2/10 of volume effortlessly fills my C-shaped 25x25 listening room to "loud conversation" levels. 5/10 of volume annoys people watching a movie 2 rooms away. As previously noted - the character changes are rather obvious as the break-in proceeds (starts somewhat congested but within few hours it comes alive). Right now Joe Henderson playing Jobim comes through precisely and evenly laid out throughout the frequency range - perhaps the lower octave not as full just yet.

I just received my Omens today. Ive been running them with a DIY 2A3 SET and so far so good. Plenty of power at 4 watts, no issues with the 12 ohm impedance. I've got a way to go before I need toake a decision but I'm pretty sure I'll keep them.

"Character changes are rather obvious as the break-in proceeds." Boy, have you ever got that right. I'm just passing 100 hours on my Essences and have experienced the same exact thing. I also discovered how much a difference seating height makes, though that might not be as big an issue with the Omens. How do you find the Omen's bass response? While the Essence can reach down there (check Lyle Lovett's She's Already Made Up Her Mind), and the bass is quite tuneful, I do find that's a bit light weight at times. I found the Essence to become much smoother as it broke in. I'm currently driving them with a Bob Latino/VTA ST70 with all of the cap upgrades. The speaker connectors are hard wired to the 4 ohm tap which to my ears produces a somewhat laid back and polite sound.

Jamich I heard the Essences connected with Jolida tube
amp ,the musicality of this combination is unbelievable,
I can feel the emotion of Elton John while singing.The
dynamics,palpability,goosebumps all in there.
