You guys got to me so I bit. I just ordered the 4a CIEM too based on the comments in the Head-fi threads. I ordered the light smoke shells, Buckeye Burl wood, and the Magnus one upgrade. I know that this combination might appear kind of boring but you can't see them while you are wearing them, right? Also, if they are anything close to what I have read they are a true bargain!
I will let you know what I think when they arrive. I will need to be patient. I will also have to sit on the sideline of this thread until they arrive.
Thanks to Brannan (at Heir in San Diego), Project86 and Poimandres for their input.
