What was the most enjoyable system that you ever put together?

So far it is my omega 3xrs with primaluna prologue 2 integrated and a resonessance dac streaming tidal hi fi using blue jean cable speaker wire and kimber hero inter connects. I haven't found a more musical system. The speakers are so adaptive they sound great with my Quinpu 6000 mk3. Thinking about trying reference 3a  Decapos. I have spendor s 3/5 and they sound veiled compared to my 3xrs. In my main system I have spica angelus and they sound veiled but not sure if it's because they are deteriorating from age . I have listened to many systems and like the primaluna/omega combo so far is my favorite. In a small room I enjoy listening to music .
