It’s a pretty in-depth review written by Marty Peters and worth picking up a copy for, if you are interested. Look's like he loved the C1 and T3, saying the C1 was a “winner” and that the T3 “closely” resembled the sound of the Microtech Gefell UM92.
He further described the C1 as being a clear winner as a “bang for the buck” mic. The T3 is further described as “not a heavily colored” mic but “more open and transparent”.
He stated that the C3 was their least favorite vocal mic in cardioid mode. However, in figure 8 and omni mode, they seemed to adore it on acoustic guitar and mandolin.
