Wow. The Spica Angelus. Haven’t thought about that speaker for a long time. That was, to me, one of the most unique looking speakers in its time. I never had the pleasure of hearing music through them.
Agree with you about the differing demands of various speaker designs/sizes. It is a long way from the Angelus to the Maxx 2!
The classic Spicas were the TC50s which had superb imaging. The Angelus added some bass extension but retained the excellent imaging, while looking like a pair of nuns staring at you. A shame John Bau stopped designing speakers!
The Wilsons also have very good imaging along with a bass down to 20 Hz and the sensitivity to operate well with lower powered amps - I change out and use a CJ Premier 11a for music and a Roland 5 for video. I’ve heard the Maxx 3 and they are indeed an improvement but the 2s are something one can be happy with indefinitely unless one suffers from audiophilia nervosa.
Any hifi addict should take the trouble to hear some speakers at least once - original Quads, Spica TC50, Apogee (preferably Scintillas), Magnepan Tympani, I’m sure many here can add their candidates for ’special’ speakers.
