I had the 3A's for 18 years before recently upgrading them to the Sig version. I do not recommend the non Sigs. They are pleasant but slow/dull sounding. The Sigs have been described as a music lovers speaker and I agree. They can bring you to the venue, meaning they convey the atmosphere and ambience of live recordings and are very good at that. They do not believably recreate the band in my room. The presentation is a little distant for that. I guess that means they are laid back. A great speaker if mid hall is your cup of tea.
