I'm a very happy LFT-VIIIa owner and highly recommend them, they compete with pretty well any speaker out there in terms of sound quality. A few things to bear in mind; they require a big-ass amp to drive'em, they take two people to put together, and Sound Anchor stands are pretty much a must. I also strongly recommend using DH Labs Q10 speaker wire with the LFTVIIIa's.
I have owned a lot of different speakers over the years: Apogee Duettas, Celestion 700's, Spica Angelus, Martin Logan Quest Z, Martin Logan Aerius, various B&W's, etc.. The closest comparison would be the Apogees, since they are both ribbon speakers they share similar qualities. In terms of how I would compare the ET's to Innersounds think about the difference you hear between a good analog set up vs. a digital source, or a quality tube component compared to a solid state design. That's a pretty fair comparison in my mind.
Click on my System and look at my main rig to get a view on the associated components I'm using. These speakers are way way too good for their modest price tag, and Bruce goes out of his way to make sure you're happy with his speakers. Buy 'em!
