@hifiman5 I have used the Eclipse 8 for about 200 hours, I tried on two different sources, Pioneer PD-D9 MKII and Audio Analogue Maestro 24-192. After your words, I will try to use the Purist Audio Disc for burn-in, in search for improvements. The sound is unbalanced, very strange, considering that I used in the past the Straight Wire Maestro (David Salz patent) and I love them.
