Our integrated amp with Bluetooth is the new generation all-in-one amplifier, combining both amplifier and pre-amp in one. The sound quality of our GIA-275 is remarkable. You’ll get grand sound quality in a small package. Lightweight but heavy power is what we are dealing with here. The GIA-275 has a very high quality converter, which can convert your high resolution digital recording into high quality sound of 24bit/192kHz, through your speakers.
