Love it. I am in the process of setting up two 3D arm tubes (was playing a Stereo 6 Eye Kind of Blue last night using one of 3D arms equiped with an Atlas cartridge). Switching from a pair of JMW 10.5i arm tubes. So this exercise hits me right tween the eyes (or, in this instance, the ears).
I strongly prefered, File A, the 3D arm. The "colorations" made the track much more involving, as it did for a lot of us it seems.
I have no intention of sending my 3D arms back to VPI. I'm all in at this point. But, I don't think it should be discounted that a significant number of us, who are knowledgable and have invested a great deal of time and money in this pursuit, decidedly prefered the metal JMW arm.
A terrific exercise Mr. Fremer. I'm (and maybe you too) are a bit uncomfortable with the results, which, at least in my case, means there's learning going on. Lets do more of these! And Thank You!
