I had been in the market for new speakers for several months, having sold a pair of Martin Logan's last year. I stumbled onto a pair of Sierra Towers with RAAL Tweeters on Audiogon and because the seller was in San Francisco I was able to audition them. I bought them on the spot. These speakers are flying under the radar it seems. I had not heard of them, but I am surely glad I responded to the Audiogon listing. I look forward to being apart of the AA community and I suspect a supporting cast of surrounds and possibly subs are in my future.
