Townshend Audio EDCT Isolda Speaker Cables

Ribbon geometry seems the way to go with speaker cables. The geometry itself is so powerful there are people who have made quite good cables from ribbon copper and packing tape. Like anything else though if you can optimize it you can do quite a bit better. Townshend applied engineering and math to work back from the desired impedance characteristics to find the optimal conductor spacing to eliminate the ringing caused by impedance mismatches that are the reason ribbons work so well.

What is odd is when Max publishes a White Paper explaining in detail exactly what is going on and why this is so, he got lambasted here by a bunch of EE wannabees. But when anyone comes along saying oh this ribbon works great this flies under the radar.

Me on the other hand, I am sure the Fidelium is at least a pretty decent cable, and probably quite a bit better than decent, because I understand the advantages of this particular geometry- from having listened to and heard just how good the Townshend implementation of it is.

I've got F1, speaker cables and interconnect. Both were a significant upgrade from more expensive Synergistic. Both have the signature Townshend sound, although it feels odd to say something with so little signature has a characteristic sound. What it is, Townshend eliminates a lot of colorations or distortions common to others. I have experience now with their wires as well as Podiums and Pods. They all have in common a clarity of detail and truth of timbre that seems to come from eliminating ringing and other distortions common to many components. The more I live with this stuff the more it seems a lot of what others are doing amounts to trying to tune harmonic distortions in less offensive ways. Where Townshend instead engineers them out of existence.

They do not "sound good". They let you hear how the recording sounds. Nothing more. Nothing less. 

Isolda should be similar to F1 only at a lower level. Hopefully some actual owners will chime in. From what I hear they are very similar in terms of what I just described, only at a little lower of a level of detail and transparency. A lot of which is probably due to the wire, as I understand it the F1 wire undergoes a special treatment that greatly improves conductivity and thus greater detail. When I was looking into F1 I came across several who had Isolda and had compared to some pretty spendy wire and said good enough, done looking. Good enough so if you got Isolda it would probably be only F1 you would consider an upgrade. But again, hopefully someone who has Isolda can say how they compare.
