Integrated amp for 2500-3000

Definitely try the Vincent Audio SV-237MKII Hybrid integrated (150/250) from Audio Advisor. The sound is very enjoyable/musical, and it has a lot of useful features. If you don’t like it, just return it - they have a generous 60-day return policy with no restocking fee,

Right now, Upscale Audio has an open-box unit priced at $2700, but I don’t know what their return policy is.

Upscale has no restocking fee, just the shipping fee. It's a great team of knowledgeable and kind people

Then you can sell the outboard DAC

Unison Research, Unico Nuovo. It'll be ready for any speaker you throw at it down the road.
