Best Pre/Amp or Integrated for Zu Essence


I am in the midst of upgrading my system. Current gear features Rega Saturn cd, Regar Elicit integrated with mc phono stage, and Pro-Ject Debut III turntable with Ortofon Salsa mc cartridge (just getting started in vinyl), Zu Libtec speaker cables, Zu Gede interconnects, and Zu Mother and Zu Bok power cords.

I just traded my WLM La Scala monitors for the Zu Essence floorstanders. Love the added dynamics and bass extension from the Zu's. I'm happy with them. I also like the La Scala's but appreciate the extra dose of vividness from the Zu's.

I am now looking to optimize my amplification. The Rega gear sounds pretty great with the Zu's, but I have been informed that tubes may have more synergy with the Essence's.

I am considering the following:
ARC VSI 60,
Audio Electronics AE3-DJH paired with Six-Pacs monoblocks,
Quad QC-24 paired with Quad II-Forty's monoblocks,
Cary 300SEI,
Primaluna Prologue 2,
Primaluna Prologue 3 paired with Prologue 7's

Any other thoughts? Budget is $4500. Since this is my first venture into tubes, I would like to stick with something that I can get on dealer demo or new.

I listen to a variety of music from small-scale classical to jazz to indie to electronica.

I am not as concerned with accuracy as much as I am with the "in-the-room" experience.

Thanks

I'm using a Decware Torii 3 with my Soul Superflys and it is leading the pack as far as all amplifiers and topologies I've tried. I am planning on trying it with a Shindo Auries-L (today actually) and my suspicion is that it will be an outstanding pairing.
Theres no question about a synergy between tube amps and the Essence. I've run my Essences on at least seven different tube amps ranging from 2A3 SETs to the ARC Classic 60, and all did very well. For a different perspective on life, try a Unison Research Unico P. 50 watts of very capable Class A biased output fronted by a 12Au7 in the pre. An extremely well constructed amp that performs very well and squeezes a bit more bass from my Essences than some tube amps. It's price won't add to the deficit either.
As an update to my prior post, I love the Shindo, but it is not the pre for the Torii. At least not for my amp in my friends system. The torii is still extremely highly recommended.
I think you will enjoy the Quad set-up. While I don't own the Quads, I have heard them numerous times as its one of the prime demo setups at a local dealer where I spend a lot of time. It's tonal quality is in between the very neutral ARC and the more lush AES & Cary's. I had the Essence a few years ago and thought it a very nice all around speaker from Zu. I thought the Druid was better (more energetic and visceral) for rock but the Essence with the ribbon was better (more detailed and nuanced) for jazz and Classical. A nice affordable high efficiency speaker. To do much better you will need to get into the much more expensive AER/PHY type drivers IMO.
It would be nearly impossible to top one of the following suggestions: Melody 2A3, Astro Black 22 (22 Watt pp, but great), Audion Silver Night (300B) or Decware Minitorii or Zen Integrated mod 3 out in March. These will all come in under 4,500 and will kill most nearly everything else. You may not like the tubes offered with each unit. Most can be tried at home so go knock yourself out and send me the savings so I can buy more gear ;-)
