Opinions on Thiel CS2?


I have the opporunity to purchase a pair of Thiel CS2 loudspeakers and wonder what people think of them? I know these were manufactured in 1988 and no modifications or driver changes were made. My main concern is what might need replacing due to age and the parts cost from the factory. I've listened to some of the later Thiel models and was impressed with the sound, but am not sure what to expect with these.

TIA,

My enthusiasm neglected to include mentioning that Thiel's Rob in the service department can give you advice and estimates on anything you might find needs replacement/refurbishing for the 2's.  That's comforting to know that the legacy models can be given an even longer life. 
I bought my Thiel CS2's in 1987 or 88 for $1500 the pair. Used them ever since. All above comments/observations are accuratee in some way or another.
I have always use solid state to run them, Bryston too bright, Hafler just right! Program material will also determine sound quality.
Agree tubes might work well with them as I may have heard them thru tubes on first audition. I didn't look at the amp. However, CS2 specs say amp power range starts at 40W. In a well dampened room the sound stage appears dead center. Hope you enjoy!
