So I got the Penon PAC480 yesterday. Fantastic value on these cables. If you guys are looking for an upgrade cable these gets a thumbs up from me. Highly recommended.
I posted this last night on the cable thread but it is my thoughts on the cable.
Sonic properties leans more toward copper cables as the bulk of the cable make up here is OCC copper with the silver portions of the outer layers of the cable being silver plating. Excellent for hybrids and all BA earphones that need some added note weight and fullness to the sonics. Very dynamic and balanced in what it does but due to copper properties your gonna get the best mids and bass your earphones can muster with the added perk of a more expansive stage. There is enough silver properties to not overly smooth out treble tones and throws out really good imaging and detial for being mostly copper. Very versatile so far as I have yet to hear an earphone yet that don't sound right using these. Highly recommend getting these in balanced.
