I also read about tubes and planars after purchasing my Audezes. I kept going to a local hi-fi shop that carries new and used gear. I tried out numerous headphone amps and nothing wowed me. I finally gave the Woo Audio a listen and it made the LCDs shine.
I have and adore these headphones. I highly recommend looking up Oratory1990s Harmon Target EQ profiles for these.
I have the Woo Audio WA7 D Fireflies Tube headphone amp with the additional WA7 TP tube power and it is a wonderful combo with the LCD-2C. I’m using Neutron Music Player to do the EQ profile and listening on my FiiO m9 Chi-Fi FLAC player. Truly delightful.
The illustrious and praiseworthy u/oratory1990.
