Good Preamp for Emerald Physics 2.3

I was wondering what preamp people have found that matched well with Emerald Physics CS 2.3? Or, does it even matter since the Behringer crossover will convert everything digital and back to analog inside it? I would hate to spend alot of money on a great preamp/DAC and it not matter since there is conversion done in the Behringer 2496 anyway. Any thoughts and advice would be appreciated.
I’m using a combination of an Audio Horizon tube DAC and TRL Dude preamp. The EP 2.3’s are very neutral and reveling speakers. They have Titanium tweeters which can be a bit bright with the wrong equipment - but with the right combination of tube source(s), cables and SS amps they are quite amazing. I have the DBX 260 and not the Behringer. I have found it to respond very well to upstream changes - tube rolling to be more specific. It has other minor flaws but does not add “brightness” to the mix in my system. If you have digital sources I can’t imaging not having tubes somewhere within the mix. I would NOT recommend TRL for a variety of reasons, but you might want to give Audio Horizons a call as they have tube dac’s, pre-amps and some other tube warmth gadget. I think they also offer a 30-day trial option.
Thanks Cdente. I do need to add a tube preamp or definitely something warmer upstream. I am considering the Wyred 4 Sound DAC-2, however it is ss. I am also considering a Peachtree Nova. I have heard the DAC-2 will best a modified Nova that is more expensive. So many choices.
I'm using an Audio Aero Prestige cdp with my CS2.3 and formally CS2.It is a great preamp and DAC.I'm hoping it works for a while cause its pricy even used.
I'm wondering about anyone trying the Spatial Audio "Orpheus'DAC and thus eliminating the Behringer xover.I have the upgraded Behringer from Cullen Circuits and it is a monstrous improvement from the stock one.But its about a grand so the Orpheus seems like a good bet as it has many more features.
Strange thing is there is hardly any feedback out there specific to the Spaital products and our speakers. I for one am not going down that road unless I'm able to demo and compare the product in my own system. The requirement of having a MAC configured with their software only makes a demo that much more of a challenge.

I've been after Cullen to provide an upgrade path for the DBX 260 but no luck. Any suggestions on how to improve 0n this active xover?
Prism Orpheus is an amazing piece of equipment. Works beautifully with the CS2.3s. It's the only way to go. When coupled with spatial, it creates jaw-droppingly beautiful sound. Behringer sucks all warmth out of the system. It doesn't work. Tube preamp only makes it worse. You have to kill the Behringer.
