I've been a big fan of Bose for damn near 40 years! 601 Series II, loved them and wish I still had them. 301 Series II was the first pair of speakers I bought after joining the Air Force. I still remember how nervous I felt spending that kind of money on speakers! I think it was $350 or so back about '84. Loved them, as well.
My First Seargeant had a pair of 501s at his house. Really enjoyed the sound of those, too.
I've owned the 901 Series VI on three occasions. Gave the first pair (along with my 301s) to my brother before one of my moves, sold the second pair when I was downsizing my gear and ended up purchasing my third pair about three years back.
The 901s driven by an Aleph 3 and Rogue 66 preamp offered THE best sounding acoustic piano sound I've ever heard in my room when I had that system in that apartment! I like having the Bose around and used them whenever the anal audiophile in me would rear its ugly head!
You know, the one who moves the speakers by increments of 1/4" many times a day over many days and is never satisfied? I get fed up and would throw the Bose in and they sounded really good no matter where I placed them.
I think every audiophile should get off their high horse and own a pair for such occasions or for when they just want to relax and enjoy some tunes without thinking and analyzing so much.
My guess is there are many closeted Bose owners.
