50+ KZ & CCA IEMs; 50+ other IEMs; 50+ DACs; 75+ balanced cables for perfect IEM-source match & colour enjoyment.
Favourite all-BA and overall IEMs: KZ ASX (wide-nozzle mode, rampant, hilarious), AS24 (gentle, perfectly fitting all my preferences with the switches), Audiosense T800 (great enjoyable V reference).
Other all-BAs: HiSenior T4, Brainwaiwz B400, BVGP V4 (least quality sound for the money in my experience). More all- BAs: KZ AS16 (original, pro, pro impedance, and pro X), BA10, AS10 (my first sweet all-BA IEM). Top hybrids: ZAT, Celest Relentless, Phoenixcall and Plutus.
Other hybrids: Moondrop May (rare value to rival KZ), CCA CA16 (grear coherent forgiving "analogue-like" rendering), 1More Penta (great treble), Simgot E6ML, KZ ZAX & ZSX. DDs: Moondrop Aria (nice old reference), KZ DQ6, HZ Mirror, CCA Trio. Planars: 7HZ Dioko (perfect/model reference for the all-frequencies spectrum), KZ PR1 Pro, Muse Power.

Other DACs: Tanchjim Space, E1DA SG3, Tempotec BHD pro & E44, etc.
