I am a manufacturer and I usually don't do headphones, but I have been invited to a local high-school to exhibit for their science fair. I am excited to teach a little here and encourage more students to pursue science and math careers. I plan to demonstrate the differences in SQ between MP3, .wav, ALAC and AIFF files. Also highlight differences between digital and analog out on an iPod, which will be my source. I will reclock it of course in order to reduce jitter to the point where I can hopefully hear these differences using my DAC.
Anyway, I purchased a Lyr Headamp based on some of the reviews I've read here and the fact that I will likely need the power for HE-400's. Really nice looks and build quality.
After a day or two of audition, I am impressed with the Lyr for the price-point, but being a long-time modder (I dont mod anymore), I wanted to see if I could make it a world-class contender using some of the left-over parts from my modding days. I thought I would share some of the mods with the world because they do add more life, extension and better top to bottom dynamics to this little headamp. These are not too difficult for the skilled DIYer.
