New/Used Amp recommendations for about $3k-$4k?


I'm looking some new Paradigm Founder Series 100f speakers and would like to get rid of my Emotiva UPA-1 mono blocks for something else. 

I really like the form factor of these amps and have been very happy having them and they will make the next buyer happy also but I want some thing very detailed and clean. 

I just got rid of Emotiva XPR-1 mono blocks after hearing the 100f's on them and could absolutely hear the detail and cleanliness those amps had with these speakers. 

What do you think?

If you want to stick with Mono's check out the Kinki Studio EX-B7's for $3500 or for stereo amp the EX-M7 for $2600

Stretch a few hundred dollars and grab a pair of Parasound Halo JC1 monoblocks.  If I understand correctly, they were on Stereophile's Class A rated amplifier list longer than any other amp.  With the newer JC1+ out for about a year, these are selling for about $4,500.

Ric has some amazing tweaks to class D amps that could make you very happy for a lot less than your budget
Maybe LSA's GaN amp being offered right now by Underwood HiFi would be of interest.
