" ... That being said, I still like the sound of this little headphone amp. ... Although the Fiio X3 has its own great built-in DAC and amplifier, the external headphone amp really makes everything sound even better. ... The Fiio X3's headphone jack adds bass and warmth, without cutting too much treble. ... It also allows the use of the onboard EQ, volume and tone controls, so that the sound can adjusted to your liking. ... "
" ... If you really listen to music closely, upgrade the tubes. ... "
" ... It has a cool metal case, with easy to move volume. ... When I have my cell on the desk and this device is on the desk safe, and is on I hear the crackle of the cell signal. ... "
" ... solid build with a solid sound in a tiny package. ... "
" ... -I fixed this by getting a ground loop noise isolator (branded BESIGN). ... -With the ground loop isolator the volume of the sound was lower than if I used no amp at all, however the ground loop was gone, and in exchange for the lower volume I also gained distorted sound if I tried to raise the volume beyond 40%. ... -tubes don't seem to color the sound or make it warmer in any way vs original source this may be a pro, i was hoping the sound would be warmer, but that's ok. ... -for the record, my audio source is crystal clear and gets just as loud as the amo without using the amp and remains crystal clear, i use dolby atmos on the source and digital eq to drive up the volume, it's not ideal but sounds better than with this amp. ... "
" ... Bought this amplifier after being pleasantly surprised with their stereo solid state model. ... "
" ... Never experiences any hums, or 'hollowness' or metal-ish type of sound from even tapping on the unit. ... But seriously no issues with other "noises". ... It all sounds incredible. ... "
" ... Volume is excellent. ... U can't have good sound just using this amp. ... "
