I am working on a pair of later SPICA TC-50s and have confirmed that the bright top end that was mentioned in several reviews is very strongly a function of listening height. Thought this page documenting the work might be of interest:

I certainly expected the TC-50's to be sensitive as far as listening height is concerned however the measurements show how extreme it really is. I was also able to confirm the mid band (approximately) linear phase response with SPICA's marketing literature.
