why doesn't everyone own a pair of spica's???

Because people are stupid!!!!!!!!
Just kidding. Spicas were the biggest bargain going when new. I still have my TC50s. They are not perfect - they don't go very deep in bass and they don't get crazy loud. Compared to the best, they are not as rich throughout the band. However, if you value natural midrange, spaciousness, and resolution they are difficult to beat at any reasonable price. The Angelus is more refined sounding. I've never heard the TC60, but they were advertised as being more dynamic.
I also greatly admired the Maggie 1.6QR, but they are much more difficult in terms of amplifier choice & room placement

I still have my original TC50s in my bedroom system, and only recently found a speaker that outperforms them in every way - Ascendo System Zs. I had some other speakers that were good, and outperformed them in terms of dynamic scale, frequency extension at both ends, other audiophile "stuff", but after teh thrill wore off, I was always frustrated by the fact that music just sounded more natural through the Spicas. I am using them with a home made sealed box sub. Before I had the sub, I had teh speakers sitting on the floor against the wall, which improved bass response, and did less harm to high frequency and sound staging than you would think.
