audiofan,
I’m a long time Audio Physic fan - have had in my room or owned the Virgo 2, Libra and Scorpio models, as well as having heard plenty other audio physic speakers. (I auditioned the latest Avanti as well this year).
I agree, the AP characteristic of disappearing as a sound source is intoxicating. They are very hard to beat. The only speakers I’ve had that do as well (aside from my MBL omnis) were my Thiel 3.7s. The 3.7s disappeared pretty much as fully as any AP speaker I’ve heard, if not more all the way to the bottom.
(But they were visually/ergonomically too big for my room so I sold them and keep my Thiel 2.7s, which soundstage really nicely but don't disappear as fully as the larger 3.7s).
For my money, the Virgo 2s had a magic tone that AP never quite recreated. The problem for me was always their bass - it was a bit coloured and wooly in a certain region that I could never get rid of.
What I love about audio physic speakers - especially in the old days - is that they managed the hard trick of totally disappearing, maintaining incredibly fine detail, yet doing so with a warm tone that really gave a convincing warm sparkle to acoustic guitar, a woodiness to wood instruments, etc.
They are a truly great speaker brand. And frankly the Audio Physic Codex is one I’ve wanted to hear, and I had urges to grab the Audio Physic Avantera speakers advertised on audiogon a while back.
