Having tried MAD My Audio Design - My Sweety Interconnect between DAC and preamp, I delved deep in my pocket and rewired my complete system with it.
Compared to the £60 interconnects I'd been using the bass came to life, had real power and impact, and appeared to go deeper. Treble was somehow sharper yet smoother, with sibilants breathy rather than spitty.
This cable made instruments and voices more eloquently detailed, a clarinet,for instance sounded more reedy and, well, more like a clarinet. Sounds that formerly were mere noise became creaking chairs or foot tapping conductors. Overall, this cable, with my equipment, seemed realistic and natural, and brought me several steps closer to being there.
