I love those amps great buy, that said I don’t think they are ideal for your speakers. They are also class A 50w amps so they will run hot regardless so I’m not to concerned about that, but hopefully someone that knows these amps better then me can chime in (I’ve owned Cary gear in the past (SLM 100 mono’s SLP 94) and had very good results. As you also know they do play and probably fairly good but i’m thinking the speakers would probably sound better with a more powerful amp. I’d continue using them for now if funds are short at the moment. when you have funds saved up then look for a speakers that are 90db or higher, there are many out there. AudioNote, LivingVoice, Ohm, Zu Audio(maybe a good look for cost to performance), Teckton (spelling), and the list goes on. don’t rule out older speakers either may get a great buy.
good luck and enjoy
