I will get into the Telos later, but start with my story on having had good luck with WA quantum stickers in several applications. I had tried one years ago on a fuse on a recommendation from Chris VenHaus of VHAudio V-Cap fame. $8 with an order for other stuff, I figured not much to lose. I liked what it did, clarifying the sound in ways I agreed with...bringing out more fine detail and space. Noticeable enough to get another next order.
Then I sort of forgot about it until years later when I was following a few threads on doing modifications on the Gustard x20pro DAC. Several of the movers and shakers on the threads had tried them on chips and caps, and really liked what they heard. The main guy suggesting them was getting the best sound cutting them up and spreading them around.
After a few of the more innovative mod contributors, some a little skeptical at first, tried and liked them....I decided to get two cap stickers to cut up, and one that was said to be good for chips....more cost than the original fuse chip, but still not much money to lose if they did not work as I imagined they would.
Though I knew a little about what they might do, a fuse is small, as is the fuse sticker, and I was surprised how much the cut up pieces spread around by-sound could do. I had finished most all the mods, so just put the DAC in with no lid to make experimenting easy. Full size, I found the WAs were over stated and dense to me, too much of their own sound. But spread around on different parts and sized correctly for each job, (to a point) the cumulative effect was more and more of that nice contribution to fine detail and space, without any of the bad. To suit my tastes transparently, I needed to make them quite small on the DAC chips, a bit bigger on the larger electro caps, and smaller on smaller caps. Finishing up, I was really glad to have the refinement, contributing to bringing up a really good DAC to a pretty great one.
While doing these modifications, I found the Telos chips, and was lucky to be able to split a box of the smaller round ones with someone. Coincidentally, another guy asked me to test the stickers he was developing. Still refining the DAC sound with the WAs, good timing for experimenting.
What I found: the Telos stickers were too dense and a little dark for me, not supporting fine detail so well in balance; the WA were prone to being a little light/lean, but really good at very fine detail, the right place and size very nice for clarifying; the test stickers were in between. I ended up using a few test stickers in the DAC, and scattered around the system; a lot of WA cut up pieces in the DAC; and no Telos. They just didn't suit my tastes, whether in the DAC, on cable ends, over power supply or electronic inputs on my computer, or wherever.
Interestingly, having blown my fave audiophile fuse with a bad NOS rectifier, I thought I would play with mixing the dark/dense Telos, with the lighter/fine detailed WA sticker and see what it would do on a glass slow blow fuse (heavier structure inside, so thinking less prone to vibration). After several experiments, it worked, 1/2 a Telos and 1/2 a WA fuse chip taped on a glass fuse brought out the best of each sticker, each supporting the other, while also sounding better than a few audiophile fuses I had tried, and approaching a favorite. A good answer in case I forgot again to pull the high dollar fuse before testing suspect rectifiers, that stickered fuse is still in the Torii. And if it blows, having taped on the stickers, I can just move them to another slow blow glass fuse.
Long story short, I like the Telos in this fuse application, but would not personally buy them again. They may be good in different setups and different needs and tastes, but not for me. I would definitely use the WA again, working well in my DAC, on a fuse, and on a few caps in amps and speakers...In fact, thanks for the reminder. I think I will pick up another WA cap sticker next time I order from someone who has them, cut them up, and try them more seriously in my amps.
