DBV#3 modified T50RP by BMF

Disclaimer: This loan has been arranged by Rick, who is a regular visitor of this blog. I truly appreciate your support, my friend! Will return the headphone back to you promptly.

BlueFlyerMonkey, the creator of this modification, keeps record of his efforts on this thread at Head-Fi.org as an open-source database. I send my sincere respect to him for his continuous devotion. BFM describes the sound of DBV #3:

Sub-bass and bass are deep, musical, and textured. Bass does not bleed into the midrange or mask the treble range. Midrange is clear, lush, and properly placed. Treble extension and clarity are improved over DBV #1. Imaging is very good. These headphones are Fast.  

PRO: Shure SRH840 stock pads definitely yield better seal and comfort.

CON: The tonality has became little too dark & the peak at 10 kHz is now more emphasized due to extra acoustic damping of the pads.

ON SECOND THOUGHT #1: Here is the moment of truth: Since stock pads of T50RP yield consistent positioning of the headphone, DBV #3 can be directly compared to the stock and LFF's Paradox in terms of internal damping scheme, and the resulting electroacoustic effect of such modification can be assessed in great detail. DBV #3 situates somewhere in between the stock and Paradox.

ON SECOND THOUGHT #2: As far as internal damping design goes, DBV #3 can be easily tweaked to simulate Paradox. Simply block the rest of the rear vents, and there you have it. Let's call it DBV-PRDX! Once the type of pads is matched, Paradox and DBV-PRDX will sound pretty darn similar to one another.

ON SECOND THOUGHT #3: DBV #3's frequency response follows Harman International's reference target only up to 1 kHz.
