Lets not forget our friend!! These are both excellent pieces of gear...I had a B-283 Tube Buffer for awhile and loved it...added that nice tube sound, I was using mine as an additional tube buffer along with my DAC --I created the FrankenDACBuffer and the addition of the different tubes along with the 5670 in my DAC kept me warm as toast!!! LOL...
Sonny (Tuan) did a cable tour with his "Sweet Spot Reveals" and they were fantastic. I found them to be very dynamic and had I needed IC's at the time his would be on my short list--they're very good!!
So here is your chance to help a fellow AC member and get some new gear while doing so!!!!
