I have a solution for your quest for an excellent SE amp... it is made my Dennis Had, the founder of Cary Audio. It is far better than Dared and Yaqin amps, no question. I have a Dennis Had EL84 SE amp for sale on this Audio Mart. I upgraded from very efficient single-drivers in my bedroom system to speakers that require more current so I am parting with the amp. You don't know mention the speakers you are driving, but if they are in the range of 94 db or better, this might be the amp for audio nirvana. Dennis's amps are legacy pieces of gear. Just my take.
