New silversmith fidelium cable

They are in my system. 795.00 6’ pair. You can bend the connector in a u shape for tight posts on mono amps. Stereo amps easy fit. 

@fxman I would be interested in hearing about your system and how the sound of it is different/better than with the cables you were using previously.

Ed Shilling at Hornshoppe Horns has been making ribbon speaker cables for many years. When I had his speakers, I noticed his ribbon cables on a photo he used on his site and asked about them. Although he didn't advertise them, he said he'd make them for anyone who asked.

They were copper flat ribbon speaker cables, by the way. They didn't look as nice as these Fidelium cables and the insulation looked like something Mapleshade made: kind of loose and baggy.

If I didn't have my present SCs, I'd give these a try.

All the best,

Just my preference, however, I’ve not cared for speaker cables that connect to the amp and/or speaker the way that there ribbon speaker cables do. I’ve tried several brands and while they sound good it seems like the attachment ends become the weak point of the cable over time.
I do admit that "The conductive surface is a .75 inch square with a .25 inch wide notch compatible with most binding posts" looks like an upgrade compared to what was done in the past.

I'm in major agreement with fxman. I've got a pair of 6' Fideliums myself, and I've got to say that I am stunned at the difference they make. They replaced my Norsodt Blue Heaven LS cables, and their improved imaging and realism is absolutely jaw dropping. I was hoping that I might might hear some beneficial difference. But I never expected a cable that was so good that I was sold before I could finish the first song I listened to. Heck, I knew I was onto something significant after just a few notes.

They are amazing. But don't take my word for it. Something like this, the word on the street will prove me right soon enough. They're just so new that almost no one's heard them. But if you can, you should, provided you have a highly resolving system.
