Coming to this discussion a bit late (is it better late than never?) I offer up an opinion and another question.
The setup: I have a pair of the Thiel CS 2 2s attached to my Krell KAV 300i. Both are 23 years old and still sound fabulous. After much research, I just purchased a used Krell Vanguard to replace the 300i. (I haven’t received it yet.) In addition, I recently replaced my Theta Miles CD player with a Bluesound Vault 2i and have loaded all of my CDs onto it (over 1000.) Note that I demoed the Vault against my CD player for several weeks before I purchased it, in addition to having many friends and family do blind testing between the Vault and the Miles CD player. The bottom line was that there was no discernible difference in sound quality. The advantage of having all types of access to all of my music at the touch of a finger is simply superb!
My opinion on the Thiels: I love their sound. They are killer when it comes to jazz, my favorite genre to listen to. They do fabulous with Baroque music, rock ‘n’ roll, blues, pop and easy listening. Classical music, large orchestral pieces, seem to be a step down in sound quality. (I am hoping it’s my amp and not the speakers; hence my buying the Vanguard. We shall see...)
My question: Has anyone out there paired the Thiel 2 2s speakers with the Krell Vanguard?
