Also, additional thanks for letting me borrow two items from his collection: the Sony MDR-AS800 and the Pioneer SE-CX9. One is a unique piece of IEM technology, while the other is one of the best-tuned budget IEMs I have heard in a while. I’ll let you guess which is which, but you can expect a writeup on both of these in the future.

All the data for the entries above have also been uploaded to the Graph Comparison Tool. Go crazy.
