I have heard the 3.7's and they are MUCH MUCH better than the 3.6's. I am not a huge fan of most Thiels but the 3.7's and the 7 series are very nice sounding. I have not heard the Wilson's but from what I gather reiterates what Stevecham says. All a matter of preference I guess.
Thiel CS3.7 vs WP8?
The 2nd hand price of Wilson WP8 is dropping down fast! I am thinking of buying a pair of 3.7 but as the WP8's price is almost within reach, I wonder which is the better choice? I have CJ premier 350 and Herron Pre. Now using Thiel 3.6 with very good results. Wanting the next step up!!
