Original Ranking

Youtube Channel
“HBB” (Hawaiian Bad Boy) is the creator behind Bad Guy Good Audio Reviews, known for music-first evaluations and a large public FR graph library that many hobbyists use to compare tunings. He’s collaborated widely across price tiers: early hits like Tripowin × HBB Mele and Olina/Olina SE, budget projects with KZ (DQ6S) and QKZ, and more recent releases such as the FATfreq × HBB Deuce and the Linsoul × HBB Jupiter.

Deuce was iterated with FATfreq around their “Basscannon v2” concept, featuring a pronounced, tightly controlled sub-bass shelf below ~150 Hz and often paired with a bass-boost adapter—aimed at delivering slam without swamping the mids. Jupiter is a tribrid flagship (1DD + 6BA + 4EST) with an ~11 dB sub-bass lift, designed for engaging macrodynamics and extended treble air. Across his work, HBB generally favors a warmer, bass-supportive balance while keeping vocals clear and treble non-fatiguing, and he anchors tuning choices to specific music rather than test tones.

PMG Audio Apx SE

  • Bad Guy Good Audio: The PMG Audio Apx SE comes out swinging with a $6,000 price tag and a $1,600 cable that looks the part but fights the ear with stiffness and springy memory. The shells flaunt real lapis lazuli ...  Game changer. Most resolving accurate replay in the hobby. No specific qualifier to wave off potential buyer..nada  Price is extreme but presentation reflects that. No sonic flaws. 1st set in 10 years that gets that.
