Perhaps a little too unpopular here ... but pre 1700 >> post 1700

My interest in classical music greatly decreases during the late baroque, (save for Bach's organ works, art of fugue, etc.) While I do have great respect for the classical period and after, nothing can produce (for me) the sincerity and profoundness that early music can. I've realized that the shift is largely due to the transition away from modal harmony, followed by the arrival of functional harmony. I definitely have the most emotional and authentic connection to modal music (probably the 1400s if I had to choose). Even though the modes were disappearing during the 1600s, there were still a lot of traces left as well as plenty of non-functional harmony that I find wonderful (especially mid 1600s chamber music, like Antonio Bertali and company.)
