"the tc-60's coupled with a good sub apparently can compete with almost anything playing anything on the market today"....
Unfortunately that is quite a bit if an overstatement!
Spica was at the leading edge in affordable high end audio 20 years ago, but there has been quite a few advances in driver materials, measurement techniques and overall understanding of crossover design since that time.
Spicas are very coherent, with a very natural sounding midrange as compared to many other offerings near their price point. BUT.... as far as "cost no object speaker comparatives, there are a PLETHORA of high end speakers (read more expensive)that will convy much better inner detail, have faster transients with more high frequency extension not to mention better dynamics and lower distortion too! (just to name a "few" sonic improvments over the Spicas ...read; "cost no object" can potentially buy much better sounding drivers and crossover parts!).
FYI: Here is a "short list" of monitor speakers I have experienced that I am very confident will eclipse the Spicas in virtually every sonic parameter:
- Ridge street Audio Sasson Ltd
- Merlin TSM MM
- Totem Rainmaker
- GR Research Dilucio
- Cliffhanger Bulldog
I'm sure that there are dozens more, but the above list I cited I know very well. I should also note that I owned both the TC-50's and the Angelus at one time, i.e. many years ago.
