Gerry we were long time Wilson setup guys and and owners.
The WP 7 is a good speaker but is bettered by today’s newer systems which are much more transparent, the Wilson sound is punchy with great dynamics. The newer Wilson are a bit more laid back in the treble since the switch to the new soft dome tweeter which you may or may not like as much.
We would recommend that you consider the new Paradigm Persona 9H they cost $20k less then the Alexia and actually outperform them.
The Personas are a $60-70k sounding speaker yet are priced at $35k
they were just awarded Loudspeaker of the year in Tone audio,
http://www.tonepublications.com/as well as receiving a similar accolade in the Absolute Sound.
http://www.theabsolutesound.com/articles/2017-golden-ear-awards-anthony-h-cordesman/When setup correctly the speaker has a totally holographic sound stage, is very transparent, and has remarkable deep bass. add to that 96 db sensitivity and built in subwoofer amplifiers powering four long throw woofers with dual 700 watt amplifiers and room correction to ensure that the speakers can work in any size room.
We have tested and listened to many of todays best loudspeakers including a $120k pair of Kharamas, the $32k KEF Blades, $70k pair of Polymer Audio Research MKX-S, the Dali Epicon $20k and a few others.
The Personas are the only reference speaker to offer the following advantages:
1: Pure Beryllium tweeter for stunning clarity
2: Pure Beryllium midrange so you have remarkable detail as well as complete coherency.
3: 96db efficiency and are easy to drive
4: 4 proprietary aluminium woofers aligned in a reaction canceling cabinet which offers true sub-woofer levels of bass down to 19Hz!
5: A rigid yet somewhat light weight cabinet designed by using 7 layers of HDF with a viscoelastic damping layers to eliminate cabinet resonances.
6; Dual 700 watt amplifiers 2 per speaker to power the woofers
7: Anthem Room Correction to apply room correction below 5k designed to align the speakers to achieve a flat room response on matter what sized room.
8: The service and support from one of the leading speaker manufactures in the world!
To understand why the Persona can do what they can do all you have to do is invest $4 million dollars and allow Paradigms engineers to run wild.
Only a large company such as a Paradigm or a B&W can invest this kind of money. The Persona’s have numerous advantages over the B&W such as bi-amping, self powered bass and of course state of the art room correction.
We have been in the industry for over 30 years, the Personas are remarkable and are a testament to how a large company can when they are committed can build one of the world’s best speakers.
They are a must audition. If you are ever in our neck of the woods we have the Persona 9H on display with the T+A gear from Germany which is also remarkably good.
Just tested a $35k T+A amp and power supply vs $90k a recently updated pair of Boulder 2050 mono blocks and the T+A actually had tighter bas,s the Boulders were a bit better but wow, the T+A were exceptionally and were nearly as good!
