Hello everyone.Back again and anxious to start soldering!

Hello everyone. Back after a long time. Have been listening to music through asus
Essence stx on my computer. Very happy with quality but thinking about class a with discrete components. Lots of heat sinks lying around. I have several good headphones BD 990, HD800, AKG 271, etc. Looking for clinical yet creamy sound. I know creamy usually means tubes but would like to try solid state for now. Any schematic suggestions? Not a pro but pretty good with schematics and soldering, etc. Any advice greatly appreciated. Thank you.
