Thanks for sharing your experience! Maybe I should try minimizing the circuit to spare the space for those coupling caps! :D BTW, this is my first post:P

Hi   I am new in DIY some amp and want to design circuit by myself. Now I want to add two buffer in my design. I don't know should I use separate decoupling capacitor on two buffer or share same set of cap since they are connect to same node. Please help! :D
