Hi Audire. This is my personal opinion only, so take it for what it‘s worth.
I’ve heard the Ultra 7s more than once in different venues. They sounded good at AXPONA, but IMO not quite at their best. There was a slight softening to its transient attack capabilities that I know is not a characteristic of it normally, nor either of my own Endeavor SEs. Still, they’re Von Schweikerts, so they still sounded fine.
I was surprised the Estelons did not sound as awe inspiring as I expected. Maybe my expectations were set too high, but I felt the extreme low end was slightly out of control relative to the rest of the range, and conversely, when pushed hard, there was a slight harshness in the midrange. I’ve read so many reports on how great these are, so this could have all been due to any number of other factors.
I thought the Stenheim Ultimes were among the small handful of best in show systems. Personally I felt they sounded wonderful. I forgot about the system and just heard music.
The Wilson Benesh / Aries Cérat room was also nice. I was only able to hear the larger pair of WBs - the smaller floor standers were apparently set up for only a short time on Friday and I missed them (I really wanted to hear those). I liked this room a lot, although IMO Robert played the music way too loud for the size of those large speakers in that size room. He wasn’t doing the system any favors. I had a couple of chances to lower the volume when he stepped out. Much nicer. Classic WB sound with smooth musical flow and very nice resolution.
Hope this helps.
