Full range speaker for rogue 90 or 100 wpc amp.

Re Thiels being harsh, I guess I'd counter with equipment matching is something you need to very much take into consideration with Thiels, and IMO the Rogue 100 wpc tubes will be a great start.  The upside is midrange tone and timber esp w/ tubes is superb, and PRAT, dynamics are excellent, bass is solid too.  Admittedly, I've also fussed about with room treatments and tweaks to help control sibilance and reediness caused I think partially by the speakers, partially by the room, and also moved to a warmer DAC.  I want to try a BIG amp and the user reviews for the new GaNs from W4S, LSA, and Peachtree have and will continue to be very interesting.   

Monitor Audio Silver speakers will be on budget and sound great with Rogue.  That would be my first choice.  

I will look into these suggestions. About the thiels are they harsh? Sometimes i hear them described that way. I couldn’t imagine that with tube gear.

thiels use high grade metal tweeters, and as always with those, if you have upstream gear that exhibit some treble grain or sizzle the metal tweeters will not smooth that over, you will hear it full force... as such, tube gear is often used to ameliorate that specific tendency in speakers with an excitable top end (thiels, kefs, focals and so on) ... the somewhat unique challenge with thiels is they are also exceptionally demanding on power amps, most tube amps just can’t handle them at any decent volume... so tubes are usually introduced further up the chain in thiel systems, feeding the tubey goodness into an iron fisted solid state power amp

With your musical taste I would think you'd be very happy with a gently used pair of Magnepan 1.7i speakers you can add a sub latter if you feel the need for deeper bass. Maggie's will bring the jazz to life in your room and do a good job on rock too.
