upgrade suggestion please for Zu Omen def

Although I am quite happy with my system, the upgrade bug bites me again. My current system has the following:

Computer
Audiogd NFB-3 DAC
PrimaLuna Prologue 3
Cary SE-1 power amp with 2A3 tube
Zu Omen Def speakers

Based on the reviews and comments, I am looking into the following options (and I didn't heard any of them)

1) replace Cary SE-1 to Melody I2A3
2) replace PrimaLuna and Cary with Almarro 318B
3) replace PrimaLuna with Supertek preamp

I think all the Melody I2A3, Almarro 318B and Supertek all with excellent feedback. The Melody I2A3 has rave review and match very well with Zu per the 6moon review. The Supertek has rave review by the community. The Almarro has rave review in 6moons as well.

Is there anyone has experience with any of them with Zu Omen Def can comment? I like to listen to female vocal, guitar, violin and saxophone. To keep the discussion focus, please limit to the options above.

Thanks in advance

Another great upgrade option is on the speakers themselves. I have had both the standard Omen Defs, and a pair with HO Drivers and upgraded Mundorf Silver in Oil Caps. Both of these made a huge improvement in the sound and took a very good speaker and made it great for me. Just my $.02.

Hi Morganc, can you please let me know which specific Oil caps do you use in your Omen Def? Is it I have to take the driver out to do this?

Had an SE1 hooked up to several speakers including Khorns. Replaced the caps with Mundorf silver/oil, hexfreds, and installed a stepped attenuator. Everything has to go through the volume control.
Cap upgrades to the Omens should be large improvement.
Very pleased with my W4S Dac.

I do not remember which capacitor it was size wise, but they are Mundorf Supreme Silver in Oil. Yes you would have to remove the drivers, and I am sure Zu could tell you the size. Also replacing the drivers (from Zu) would also be a huge upgrade. Both of those for around $500 would greatly improve the speakers.

I just pulled the drivers on my Omen Def and it looks like the capacitor value is 1 uF. I have sent a note to Zu to confirm that. I think I will try that upgrade (that looks to be one of the differences in the Superfly).
