Integrated Amp ideas for Dynaudio Special 40's

Looking for some ideas on integrated amps for my special 40's. I'm currently using a Peachtree Decco65 to drive these, but my sense is that it's not doing them justice.. Would prefer to use an all-in-one integrated (including DAC), but also open to other ideas.

I'm considering the Peachtree 220se--any opinions on whether this would be a noticeable upgrade to the Decco65?  Also curious about the Nuprime ida-8 and Hegel H80/H90... Would like to keep budget under $1500, and willing to buy used/demo/refurbished as well. Any other ideas much appreciated--
