Down sides I agree with in your quote and I’d add they didn’t do dynamics very well (think orchestral music, rock etc etc). Otherwise, if you’re into mellow listening, they were really good.
I don’t know that I would have called my preference (now a days) mellow listening, but usually it is a smaller presentation that I listen to and usually it is the vocals that I am most attracted to, so maybe I have actually slid into a state of mellow listening.
And I’d keep my B&Ws, so if I felt the need for speed, I could hook them back up. Besides considering their low sensitivity, I guess I am also weighing the fact that the pictures of them show them to be a bit dinged up, and I don’t know that if even if they are about 4k cheaper than brand new that this condition should rule them out for me or not. Kind of like a gear head who sees a 427 Vette (although these are not a Vette) with dings and dents and the numbers not matching that he couldn’t afford otherwise.
