I am listening to Gustav Mahler Symphony # 10 Sony WM1A >balanced High Gain> Sony Z1R. The whole ochestra is beautifully rendered and the very low notes are visceral.
Ihve the following cable on order:
Forza AudioWorks Noir Hybrid HPC - Cable : Octa hybrid semi-Litz UPOCC Cryo 7N wire (4x2 geometry), Headphones : Sony MDR-Z7/MDR-Z1R, Length : 1,5 m, Plug : Sony 4.4mm TRRRS Balanced, Splitter : Forza AudioWorks CNC 260€ incl. shipping.
This is not so much for even better sound(no cable soud beliver here), I just need a very good 4.4 mm terminated cable in case the Sony cable dies. This is the third cable from them, I already have one for the DT1990 ab one for the Sony Z7. Both are the pure copper variant and both are 1.5m for conveniance. The build quality is superb.
