Thanks for clarifying. That is why things seemed and looked a bit off in Electri-Q after performing the Q to BW conversions. This seems to have fixed things a bit.I have done some more serious, reflective listening to the Tascam TH-02 to avoid any placebo or listening bias. It has become apparent despite my hopes that the Tascam TH-02 has some sort of housing resonance that do not register in Innerfidelity's distortion graphs. This problematic resonance can be remedied with a few household items and a couple inexpensive materials from a local home improvement store. purrin has kindly created graphs of the frequency response and the various orders of harmonic distortion that more accurately follow what I am describing from my listening tests. In addition, purrin also describes a modification which involves applying some Dynamat, stuffing some acoustic fiber and inserting one-ply toilet paper reducing the treble spike and the chamber reverberation. Useful images of some graphs and modifications can be found at the end of this post for those interested. Credit again is given to purrin:
