I've just got the 0,6 OTA power cords for a trial. The cables were well burned-in: they spent some time in a 47 labs system. The IEC connectors are made of a very light plastic, from Japan. The cables are longer than usual: over 3m. These power cords were designed for 4 power supplies/components: 1 AC plug and 4 IEC connectors. My 47 labs setup consists of 2 power supplies so 2 wires in this setup are excessive. I think it will degrade a little bit the effect of these cords. After only 2-3 hours the sound stabilized so I started to listen.
The first impressions are very good, I would say excellent. The sound opened up beautifully with more air in the treble region. Extension is better, both in the bass, which is now fuller and has more weight, and in the treble that sounds cleaner and smoother, with no grain at all. The soundstage is now bigger (positively, the proportions are just as they should be) spreading in all directions with more space between instruments and voices.
Also, the dynamic is improved. Everything breathes more easily with a lot of details. Voices sound smoother and more natural.
The 0,6 OTA wire as a power cord brings new improvement in my 47/essence setup. It brought power and dynamic without sacrificing anything from the 0,4 wire’s virtues. In fact, the 0,6 OTA surpasses thinner wire in every respect.
One thing concerning the bass: it's certainly fuller and deeper but I notice a hint of softening in the mid-bass region. Is it because of the 2 excessive IEC plugs that just «steal» some AC power? I don't know, but I'll definitely get some 0,6 OTAs (for PCs) for myself.
