1. The i3 pure tube amplifier mini power amplifier has 3 outputs of fully balanced amp, single-ended amp and speaker. The amp part is driven by a balance transformer, which can drive the hot and hard-to-push headphones on the market with ease; 12w pure tube The output can drive large bookshelf boxes and small floor boxes easily, and the sound is mellow and transparent. 2.30 years of tube amplifier manufacturing expertise, all-aluminum precision work, original circuit board scaffolding technology effectively eliminates component interference, and brings you an extraordinary sound quality. The coupling part uses 4 German WIMA Weimar capacitors, and the filter part uses 11 Japanese original nichicom Nichicom capacitors. 3. Bluetooth 5.0 lossless transmission, with Bluetooth connection, using American Qualcomm QCC3034 chip, with fast transmission capability, and support for high-definition audio format transmission. Specially designed auxiliary audio circuit, the sound field is full and elastic, the tone is delicate, rich and smooth, and the outline of the line is glossy, which is comparable to the sound quality of CD. Support SBC, AAC, APTX, APTX_LL, APTX_HD, LDAC format transmission.
