I found them to be more natural in the bass than a Dynaco A-25, which I thought was boomy.
I found them to be clearer than an AR4ax and KLH Six and Seventeen, both wooly on the top end to me.
I found them to have better midrange/vocal capabilities than the EPI 100.
In fact, a bit surprising to me, I found them an equal to offerings from aDs.
It's a speaker built by Andy Kostasos/Petite, who worked with henry Kloss. Andy did a good job at bringing quality sound at a budget price to the consumer, much like Advent had done.
Is there better? Of course. But for what market it was designed for, it's a winner and performs well beyond it's capabilities.
Bass isn't room-shaking, but is pleasant and natural sounding. The upper models like the A150, A200 and A400 are better than many speakers of that time period that had cost much more.
This is not an "exciting" speaker, but natural in it's quality. Nothing leaps out at you, but everything combined as a cohesve whole works out to be a quality package that does so much right.
I found the early model SEAS tweeter to be very accomodating.
I found the BA tweeter to be bright with my Yamaha gear, but perfect with Sansui and Marantz.
