AIYMA Low Pass Filter - Worked Perfectly and very clean. Looks like legit Texus instrument chips too. Gain was good, not amazing. https://www.aliexpress.com/item....2o4rLx6 AIYIMA XLR Balanced Output Amp - Terrible, maybe I got a bad one, but the gain was useless, pretty shitty Op Amps. Do not reccomend buying - https://www.aliexpress.com/item....2o4rLx6
