Review on AIYIMA T8 Preamplifier Bluetooth Headphone by Jonathan Jensen

This is my first experience with tubes and I love it! It brings a new dimension to music. I also hooked it up to a Crown 1502 and it achieves all the detail, clarity and breadth that I wanted with my Nad 748 preamp and 10-band EQ. I set the tone controls near the center and this brings clarity, naturalness and richness to my varied recordings. The board is great and the quality is good. I connected it through the headphone output (which I was told has a better chip). One thing I've noticed is that with longer leads to the amp, using a heavier gauge cable makes a difference. It seems to depend on the depth, breadth or openness of the sound. It also seems to get easier on the ears with an increase in detail. I know I don't have a very expensive sound system (other than my Martin-Logan esl) but this inexpensive preamp was a great addition. (and to think he only has ONE whistle!)
