Wilson Benesch ACT

I owned the WB ACTs for over two years and found them on the warm side with a golden midrange and balanced frequency response. The bass is smooth and provides a nice foundation but lacks attack and low range oomph- I ended up buying the WB Torus infrasonic generator to pair with the speakers. The ACTs were also fairly transparent to the source. I've owned Kharma, Genesis, Wilson (Watt Puppy series), Verity Parsifals as well as numerous other speakers and would put the ACTs in the middle of the cold-warm spectrum with Kharma and Wilson leaning toward blue and Verity and Genesis leaning toward red.

Gear was mostly solid state, Class A amps (Lamm tube and hybrid) and Esoteric digital. If you find them fatiguing, check the gear that is driving the speakers and compare with your own setup to see if that is the issue.

I think these comments really do prove the adage that you have to listen for yourself. Where I found them a bit sterile and sharp even on tube amps (Manley snappers, ARC VSi 60), Classicjazz found them warm with solid state. Maybe his use of class A amps is the difference, which could also explain why he found the bottom end lacking oomph.

What a crazy hobby.

I own them and love them. Edorr describes them well. They are fast accurate, transparent, tight ( but not real deep) bass. They don't inject a lot of warmth into the music (may be because of the carbon fiber cabinet) but the instruments separate out in space nicely so it doesn't sound like the music is coming out of a box. Also, they are extremely revealing of what is upstream. That being said, I can see where some can find them dry, uninvolving or edgy. I get a rich tone and warmth from my analog rig and 300B tube amp, along with the speed, accuracy and coherence of the speaker. That works for me. I can listen for hours.
Be careful with what you pair them with. I can see where they may not work with some gear.
