Why Don't you hear more about Audio Physics Speakers??

I have Avanti IIIs. I got a great deal on a pre owned pair. But they really didn't sound as great as any of what I read. Disappointing. I put them away. Then I actually read AP's set up guide and one day dragged them out and tried that. Huge difference. Then I better matched components, even better (4 different amps and settled on a Naim). Then I raised them a tad on higher spikes. Better. Then I added a sub. Which I thought I shouldn't need, which is one reason I got them. That was the final enhancement. They sound better than anything I own or owned. Really beautiful on well recorded classical and jazz. But....a big but....that room is only that. If you are someone who can be a slave to a single sweet spot which the whole room and all your stuff serves, go for them. But if you want to do anything else or sit anywhere else in that room you are better with something else. My room is the old playroom, cleared out with just bookshelves against walls the system against a back wall, the speakers pulled forward 9 feet apart and a chair 8 feet away centered. I have a desk on the back wall and if I sit at that desk, with the chair only about 5  feet beyond the "spot" I may as well be listening to the radio.

I own a pair of the Avantera IIIs for a couple years now. I own Focals, Raidhos, and Dynaudio and out of all of them these speakers sound the most like real instruments playing and real singers. It took awhile to get the right amplifier--currently the Hegel H590. With this amp they are a bit cool, but the sound staging is huge. Plenty of bass and a luscious midrange. They are in a gorgeous ebony finish (matte not gloss). Sadly, I must let them go as I am retiring and they will be too large for my new much smaller digs.

I have a pair of Audio Physic Avantera, bought dealer demos in 2019.  I think they are terrific.  I was moving to a different house, needed speakers to fit a 13 x 22 room.  Driving them with Esoteric amp and preamp.  Source is digital streaming.  Imaging is amazing, speakers disappear, and really can hear deep into the recording.  There's plenty of bass, its taut and tuneful not earth shattering.  Don't use analytical or bright cables because they can get a bit edgy, I use Cardas Clear.   

They don’t have a wide distribution net in North America but they make some competent speakers.

I owned the Avanti (current version) for a couple months. Overall, they were a good value at the price I paid for them pre-owned. The cabinet finish is second to none. The only complaint I had with these was some cabinet resonance that sometimes distracted from otherwise great performance. I didn’t notice a lack of low octave extension as others have mentioned. In fact that was one of their strengths. They just lacked the 50-100Hz hump that many tower speakers produce. So if one is used to that midbass hump then I can understand why they’d sound lean.
 

At the retail price of the Avantis, there are better options, like the Spendor D7.2.

Heard the Tempo Plus at Holm Audio here in the Chicago suburbs, and some things were amazing and some I didn't have much of an opinion......just so so. The only speaker I've ever heard where the soundstage was almost the entire room, up/down/sideways/wide. They are also the only speaker I have ever heard that I had no idea where the speaker was, sound just enveloped me from all sides.....and that was in a crowded sound room.

However, they did not "excite me". Impact was not there, gorgeous sweet mids were somewhat there but un-exciting, and transitions seemed to be "lazy" or slow.

Wanted SO much to love them as they were on a ridiculous sale, but just didn't fall in love with them
