I have a friend of mine who I call "Vintage Joe". He has had all of the above mentioned speakers. Depending on your price range and room size the best speakers I heard from his system was the IMF 50s and up. Large box style floor standers. I also agree with KEF 104/2s and 105s and Dahlquist DQ-20i's.
Recommendations for Vintage Speakers
I’m currently looking to put together a vintage system and am wondering what a good pair of full range, floor standing speakers would be. They would be powered by a Pioneer SX-1250. I listen to a very wide range of music, a lot of live Grateful Dead, Classic Rock, Metal, But also enjoy Jazz and even a little Big Band music once in a while. Thanks for your help!
