I've had the 3A Sigs. for a few years and really like their highly musical presentation. However, I've always been slightly disappointed by what I've felt was slightly limited bass extension and definition. When I first bought the speakers, I talked to some 3A Sig. owners and a couple of them said that the speakers were capable of producing terrific bass. This didn't happen for me and I've always felt something was slightly wrong even though there have been a lot of amps and speaker cables through my system in the last three or so years since I've had the speakers. Because of this, I too have been thinking of the 2WQ subs.
The amps have all been solid state, some very powerful including a Classe CA301. Presently, I'm using two Bel Canto 200.2s. Although I've been through several speaker cables and had just about given up in that area, I had a strange thought about trying some MIT cables. I've never had MIT and thought the boxes were hokey and the prices inflated. But, Joe Abrams had a new pair of S2 Shotgun biwire cables for about half price, so I decided to take a flyer.
Break-in is a little tough with MIT, but now that there are several hundred hours on the cables I can report something that, to me, is amazing. For the first time I've got bass extension and definition to the point that I now think that the very bottom is one of the best characteristics of these speakers. Mid range is full and well textured and the high end has plenty of extension and sparkle.
I still think the large network boxes are hokey and I don't feel any desire to try their interconnects. Nonetheless, my hat is off to MIT for giving me the speakers I originally dreamed of owning. If your wallet is bulging, there are several models above the S2 Biwires presumable offering even further improvements.
