I must concur with all the positive voices here, truly appreciating Frank's work, aka Toxic Cables!
Having had some experience of his products (copper / silver plated copper for the HD650 and LCD-2), the first thing that hit me was the absolute perfection of his master craftsmanship. Those words are easy(ish!) to say, but it is rare indeed to find the genuine article, and Frank is the real deal. I too have had experience of swapping emails with the man as he works on a cable at 05:30, having started work at 11am the previous day! When indeed does the man sleep?!
With experience of his low-priced models, I felt safe to take the step up to the pure silver (with 1% gold), Silver Poison, and I'm certain I will love it! It has not taken long for his products to gain a degree of "mass appeal" here in the hallowed halls of Head-Fi, and I think his pricing has a lot to do with that. I haven't seen any of the big names really serving this niche market with cables for cans of high quality while abbreviating price tags to less than 3 digits... But as we know, Frank doesn't just dip his toe into the tip of the 2-digit price range, he dived in and came up with several models to choose from - and they're better than competitors costing two or more times the price (again, mentioning no names).
So, suffice to say that I'm quite excited about the forthcoming arrival of my very own sheathed Silver Poison!
