ADV. GT3 Superbass IEM

Lol, no its not that I dont like using wireless, I love good wireless. PA systems dont support bluetooth-out about 100 percent of the time, which means bluetooth DAC/Amp's are essentially useless and the only reliable way to process a signal on the artist side is through analog. Wow the Fa9 do look good, however, typically the output impedance for PA is between 10-50 ohms which means that if I want to follow the impedance matching rule of 8ths I would need to use an impedance of at least 160-ish ohms which is why the 80 ohm impedance of the ADV Gt3 superbass was appealing. Still, I will keep an eye out for specials on the Fa9, I have a pair of FH1's and I like the way Fiio uses their BA's. I can notice the difference between basic android codecs but Aptx and AAC are much harder to tell the difference on. The basic android codecs (a2dp and the like) sound compressed, unnatural and can have digital/grainy sounding high end. One of the interesting things about digital compression is that the highlights of a song (e.g. sax solo) don't stand out in the mix as well and get more covered up which is something that a lot of bluetooth codecs share. However, this is me being super nitpicky and realistically in day to day usage I dont notice it unless the bluetooth controller on the receiver side is particularly bad. The main things about bluetooth IMO are noise floor, that disgusting sounding high end and instrument separation on inferiors codecs.
