Meitner MA3 amp/integrated suggestions

I recently picked up a used Meitner MA3 to combine my streamer and DAC into one unit. I've been blown away by this unit and it's DAC, but more surprisingly it's preamp/volume control have been excellent! I'm currently running it directly into my beloved Oliver Sayes 421a tube amp, with excellent results. 

Since I listen almost 8hrs a day, I don't want to burn my tubes that much, so I thought I'd look for a solid state amp, or integrated. Reason I thought amp first was because of the excellent volume control on the MA3. 

What are you guys connecting the MA3 to? wpc not a concern since I use highly efficient speakers. since this won't be my main amp i'ld like to find something in the under $3k used budget. Suggestions welcome
