I have an idea that might work, emphasis on the word might. This amp right here: https://diyaudiostore.com/collections/amp-camp-amp/products/amp-camp-amp-kit?variant=7072933085218 is an easy to build single ended transistor kit. It sells for $327, but if I recall shipping is expensive because the case comes from Europe somewhere. It is designed by Nelson Pass, and has a true single ended sound without the impedance and damping problems a triode tube would have, but it is still only 6 watts. Although I bet this amp would drive your speakers, it would not be ideal. I agree with the consensus that different speakers would be a requirement for true single ended nirvana. The trick is; it is a few hundred bucks rather than a few thousand and it would give you a taste of what the single ended craze is about. You would have to learn to solder if you don't know how already.
After I built my first S.E.T. amp (45 tube, 2 watts per channel), I spent 20 years looking for a true full range speaker for it. I wound up building a large, make that very large (even I wouldn't have it in my living room), Altec based horn speaker with a RAAL ribbon tweeter. The system is tri-amped. I use this amp right next to my S.E.T.s ,for driving the tweeters.
