I heard the Bose 901's at the local Hi-Fi store when I was in college. They were outstanding and raised the bar for me of what a good sound speaker system could be. As a college student with just enough extra money to have food and play some video games for entertainment, I foolishly spent what little money I had to spare on a pair of Bose Roommates which were very distant cousins to the Bose 301's and an early Sony portable CD player. Best small portable speakers and a handful of CD's in a portable player that I could not quite afford made listening to music wonderful. Almost twenty years later my Bose Roommates bit the dust. So from where I was listening in college, you have the untouchable mac daddy Bose 901 speakers system. "Music is in the ear of the hearer."
In a way, we may be in the same "boat," as I am upgrading my system from a Geneva Sound System which may be the modern day equivalent of your Bose 901's, but my system is almost unheard of and unseen. Now, I am looking into a vintage analog tube amp and pre-amp, and electrostatic speakers with help from the gang here on the forum, but of course still on a small budget. The adventure begins.
