I prepared this cable with ETI Legato plugs Schuko and IEC, don't use FI-50 NCF like most people and distributors do. I had read, that sometimes with NCF sound isn't as floated and excellent, like with gold-plated Wattgate or other plugs. ETI are the best from I knew gold-plated plugs, so I matched them with DPS 4.1. The power cable I connected to power amplifier Audia Flight. Compared to TCS-31 the sound is more cultural, more smooth, more detailed, more precise, more weighed. The differences aren't dramatic, rather like progress in all aspects. But if you want to find even the small progress, if money aren't problem, then the cable with good plugs can improve your system and will give you smile on the face, when you'll hear more and more and always beautiful.
