I got Whiplash JH13 balanced cable so I can try Protector in Balanced mode.
Now my setup is iMod 5.5G + ALO SXC cryo + RSA Protector + Whiplash SCSCag + JH13.
I was so impressed when I hear the sound. I have been a heavy portable amp user since I got original SR71 in 2005. But Protector provides whole new experience to me. The spatial sense is unusual I have never experienced in portable gear.
Yes the soundstage is huge and wide but the most notable difference is on depth. The sound from this combo is not a 2D papertoy, now the sound is 3D sculpture with vivid rendering. This is a kind of magic.
Not only imaging is amazing but also I felt the sound has a firm weight. Not faint but strong like steel.
I remember this feeling. First time I heard balanced headphones, I felt similar feeling. That was GS-X with HD650 balanced. I think this new experience is a virtue of balanced headphones.
Jazz piano-trio reproduction is a strength of JH13, now this is even better than before and more life-like. Now rock sounded powerful and punchy.
I changed cable as well, so some of the honor may goes to Whiplash (
mine is SCSCag).
I think this cable is quite nice JH13 replacement cable. Good timbre, good bass. Sharp but not being harsh. I am thinking to get Single-ended one for HM801.
In these days, Hifiman 801 impressed me much for its strong source circuit which employ high-end PCM1704.
So my mind was about to lean towards the idea that the iPod based portable amp is now obsolete. But I was wrong.
Protector proves.
