Not long winded at all - Dan.
In fact, very informative and your findings are spot on along w/ mine regarding the Vandy Quattro. I did not care for the Treo model either?
During my audition period I did like the 3A Signature, still, the Thiel CS 2.4 was better, more realistic in musical timbre. I look forward in reading more of your contributions to this group.
Happy Listening!
