On the hunt for a non-tube preamp (or hybrid), long post...

Once again I am bitten by the bug and seek advice from the all-knowing.  

I decided to put together a non-tube setup, primarily to satisfy curiosity.  

Current gear

1. Rogue Magnum Cronus III
2. Erhard Audio Aretha (6SL7 preamp)
3. Dynakit ST-35 (EL84 power amp)  
4. Magnepan LRS+
5. Omega Super3 High Output XRS Wide Baffle style (This exact one https://www.instagram.com/p/CinkR-KP5ot/)
6. Chord Qutest
7. iFi Zen Stream with iPower Elite power supply

So as you can see, I'm tube heavy at the moment and my main system is the Rogue through the LRS+.  I recently took part in the Orchard Audio trial of Leo's phenomenal Starkrimson® Stereo Ultra 2.0.  I paired it with my Erhard Aretha using XLR to RCA adapters and, not ideal, it still sounded clean, crisp and dynamic through the Magnepans.  I like the tube pre with the GaN transistors combo for sure. I think I want to go in the direction of full balanced XLR just for curiosity's sake.

My question: How about a preamp like the SST Ambrosia 2000 paired with a SST Son of Ampzilla II or maybe a Black Ice Audio F360 paired with a Class D amp of some sort (Bel Canto e.One REF600M, Orchard Audio Starkrimson, etc.)?  I'm not sure if the SST Ambrosia 2000 is still recommended over some of the other newer preamps from Pass Labs or similar, I just really like how it looks and I'm sure the synergy with the Son of Ampzilla II is a given.

I just want that punchy, textured sound from a higher watt/current system to drive my Magnepans.  Budget is around $5,000 and I'd likely have to sell a few things.  Just fishing for opinions - apologies if I rambled.  Thanks!
