Definitely cables make a difference, that's why I experiment with making them. It's a fiddly job, that takes time.
It's not really about cables being better or being good. It's how they sound different to other cables, on any given system, and how we can use them in the mix for tuning our systems.
What do these cables do for me, on my system, is they add a liveliness to the sound. My tannoy system is nice and warm, and engaging (they have a beauty about them). My dac "needs" some extra transparency at the front end, as the whole mix is bordering on too much of a good thing. I actually don't think the Yamamuras are the answer for my Dac to Passive spot in the system.
So my DIY's give me extension and transparency. I was hoping they had inherent body aswell, given I have used 20awg Neotech, but they don't have this, when compared directly to the Yam-5000s.
Pros/cons, just different flavours is all.
Stevens system has "you are there" transparency, and my DIY's didn't gel on that system.
Hope that adds context around what my cables do, compared to a known quantity.
I will go on to test the Copper Harmony plugs as planned. But I also intend to try cotton sleeving instead of Teflon tubing, not too far down the road.
