I also agree with others - upgrade the speakers before going with a new amp. Or, do both. You can find pretty good tube integrateds used for $1.5-2K and decent speakers in the same range in the $1-1.5K if you’re lucky. I saw a Tekton Perfect SET selling for $1200 a little while ago. I’d bet that would be great with the amps you list and you could find both under $3K together if you are patient.
