Quantum Science Audio Thread

Has anybody tried the receptacles from QSA? Looking for something to tinker with even though everything sounds great. I have a Furutech NCF in the wall that has been my mainstay for quite a while so wondering if anybody has had good luck with one of the QSA's besting it.

I currently have a yellow fuse in my amp, a yellow in my preamp, and a violet in my dac along with red stones inside my breaker panel. This is the best sound I’ve ever had, by far. So engaging and seductive. I want to listen for hours. Awesome products!

Wow, great read. Thanks for the post tommyu!

I’m wondering if the end caps of the fuses being coated with 1260 or TC paste affects things negatively after reading this part...

The metal caps at both ends of the fuse are coated with micro-nano oil to make the contact points closer. 

I have a pair of clear stones taking the scenic route (thanks post office) to me this week and will get the blue or open stones next week. So that will give me the complete set, but the red stones on their own are pretty good.Would love to try one of the receptacles but it might be a while.

My experience has been when going from the light blue to the yellow and the violet you just get more of everything that you get with the blue. More presence and a sense of a deeper soundstage while still having the tube like musicality and tone the blue gives you. Instruments and vocals have more realism too as you go up

When I told Mike the violet was already making me want to try a red he said in his opinion the biggest jump in performance among the fuses was going from violet to red. Thankfully the 90 day trade up program allows a little bit of time to make that decision. 

I agree with tommylion in the comparison with the QSA light blue and the SR Orange. When I swapped the Orange treated with PPT paste out of my dac for the light blue it was instantly better in every way. The amount of detail retrieval while still being very musical and tube like in its tone and presence just makes for me a no brainer between the two, especially given the QSA blue is less than half the price of the Orange.

I've moved on to a yellow and now a violet in the dac and everything keeps getting better with more realism and a musically engaging experience. I have a violet on order to put in my preamp and also ordered a light blue for my Add-Powr Wizard to try.

Would like to try one of their receptacles to compare to the Furutech NCF's that I've been using for the last several years.

ozzy- 

Where in the chain is your red fuse? I thought you mentioned it somewhere but can’t find it. 

Jetter- you don't have to buy it and if you do you can send it back. No one is forcing you to do this.

The red were the first stones I tried and the only placed I liked the difference was inside the breaker panel. I agree with Miller that the other two types made a bigger difference in my system. 
But if you’re not getting anything from the red then maybe best to send back.
