I am totally with you as it relates to my main system. Due to work and family it probably gets five hours in a good week. It used to get 20+ hours a week when my work desk was in the same space, but since moving the desk not so much.
Until I rearrange again I decided to invest some coin in a better than average desktop system. Totem speakers on ISOAcoustics stands, a nice sub, Kimber cables, a Yamaha amp, Roon running on the PC. It gets 30 hours a week use.
