I was searching on this topic and didn't find a dedicate thread. So I'm staring one, and let's gather more ideas for the community.
So far, from the reports by several members, the LCD3 sounds very nice paring up with
Tube amp: Leben CS300X (SE), Woo Audio WA22 (balanced)
Solid state amp: from my experience, the Harmony Design EAR909 (balanced)
Hybrid: RWA Audeze Edition (balanced)
Please share your suggestions!
