Tube amps good with Emerald Physics CS2 speakers?


Hello everyone. I just bought a pair of Emerald Physics CS2 speakers, I know that these speakers need to be bi-amped, and I am now looking for the amps with which to drive them. I spoke to Clayton, (the designer of these speakers), on the phone, and he said that for the lower frequencies, that the CS2s need at least 100 watts to be driven effectively on the low end, and so then he recommended that I use a solid-state amp in order to drive the low frequency woofers, and so I will look for a good solid-state amp to drive the woofers of the CS2s on the lower frequencies. I also asked him about what type of amp I should use for the higher frequencies, but he would not give me a recommendation as to whether or not I should use tube amps or solid-state amps on the high frequency tweeters, saying that he had customers who were doing both and were happy with them. And so, I am asking my questions to and referring my questions to you guys who already own these speakers and who have had experience with them: can you tell me which would sound better driving the high frequency tweeters of the CS2s--tube amps or solid-state amps? Has anyone actually tried driving the tweeters of these speakers with a tube amp, and did it sound good and was the sound to your liking? And also, has anyone actually tried driving these speakers with SET tube amps, and did you think the speakers sounded good driving them with those amps, and was the sound to your liking? I was also looking at a specific tube amp to pair with the upper frequency tweeters of these speakers, and that is the Art Audio Carissa Signature 845 SET tube amp. I was told by Clayton that the power output of this SET amp would be enough to drive the upper frequency tweeters of these speakers due to the use of the 845 tube, but he had never heard of the amp before, and so he could not say whether or not he thought that this amp would be a good match with the CS2 tweeters or not. Has anyone had any experience pairing this particular 845 SET amp with the CS2 tweeters? Has anyone had any experience trying to pair another 845 SET tube amp with the high frequency tweeters of the CS2s? And if you did, did it sound good, did you like the sound, and did it sound musical? Everyone’s input is appreciated, and all are welcome to reply, but I would especially like to hear from CS2 owners and those whom have either tried to use tube amplification in order to drive the upper frequency tweeters of these speakers and who have had experience with using tube amps with these speakers, or those who have heard the speakers before being driven separately by both solid-state amps and tube amps.

Thanks in advance to everyone who replies.

I'm trying to understand where the Emerald Physics DSP sits in the signal chain. Is it between the preamp and the amp? Is it between the amp and speakers? How does it connect into the system? Thanks.
The DSP is between the preamp and the amplifier. The amplifiers connect directly to the drivers of the speakers.
Thanks for the response re where the DSP connects in the signal chain. I have more questions. Does the DSP have both analog and digital inputs? If so, which input do you prefer to use and why? I suppose the DSP analog output is divided into a pair of LF outs and HF outs, correct? It's been my experience that some speakers sound better at higher volumes. How do the speakers sound at low volume? How well can you hear into the recording at low volume? I have heard Zu Audio Definitions, how does he Emerald Physics compare, soundwise?
Dont see where running tubes into DSP makes sence. Might as well use SS. And the DSP is needed for if not no bass at all, DSP is a way to try and cheat the laws of physics. As with all things computer equiped bet these loudspeakers wont last as long or be worth much in the future. Ever priced a 5 year old top model HT receiver or CD player? Since we all know at what speed digital advances. Sure DSP could be the future of loudspeakers but I feel all would need to be designed as a whole, transducers DSP cabinet etc. Maybe EP did this but when I looked them over I didnt see it. Also design would need to be upgradable like a PC does EP offer this?
