upgrade suggestion please for Zu Omen def

No... he has Reference 3A deCappo's.

I have the Omen Defs and I have had two I2A3's in my system, that is how much I liked them. I have not heard an Almarro, but I tried to buy one twice and lost it as it sold quickly. For the price used, either one would be fantastic for you I would believe. I can say with vocals the melody is fantastic.

I think you would get more bang for your upgrade buck by changing amps and trying out a new DAC. I have found minor changes in my Zu system with pre-amp changes and huge changes with my amp and Dac changes. However, the good and bad about Zu speakers is that:
1. Every weak point in your system will hold it back. That could be your Dac or your computer, or both for example. Even power conditioning and the like.
2. Every upgrade that you make will bring noticeable changes to the system as long as there are no obvious weak links.

And finally I would suggest in your price range a Tekton mini Lore or Lore. You will not find a more tonally accurate amp for your guitar, violin, etc IMO.

Good luck!

I got my brain all haywire.....the last line should be Decware Mini Torii or Torii! If budget allows, the Coincident Frankenstein is the best I have tried (disclaimer I am selling mine because I upgraded to a newer more shiney version).

Thanks for all the reply, I think I will get either the Melody and Almarro whatever come up first. The challenge is, they are very hard to cross by, and I missed a couple Almarro in the past. They are gone too quickly ...

The MasterSound Due Venti is better than the Almarro. They pop up from time to time.
