Subs can get you there for sure. Buy a solid SS from a company that has a trial period and see what happens. Personally, I like the set and forget approach. Constantly changing settings would get tedious to me after a bit. I’m all about finding a sweet spot and letting it be. The only way to find out for sure is to audition a few amps. Your current tube amp may not have a high enough bias to drive your woofers well at low volume. Maybe play with that if you an adjustable bias setting.
will changing to solid-state make the bass in my wilson sophias better at low volume?
I've noticed that my sophias really shine when they're cranked up a bit, which is great, but I'm wondering if I can't get more of that, esp. the bass, at lower volumes. my tube amps (Cary Slam-100s in triode) are ~50w/ch, more than the 25w/ch minimum wilson recommends. it seems to me that I could either get a sub or try a solid-state power amp. it'd be easy enough to try either/both, but I'm curious what people have to say. thanks!
