These amazing cables come from Mr. Sunny Lo formerly of Sunny Cable Technology. The cables are priced very fairly. The XLR and RCA cables are 1-1.5 Meter. Prices range from $300-$550 depending my on length and connections. These are dynamic crisp & clean with great bass and very quite. All cables have grounding wires attacked to if choose to do so. The soundstage is remarkable back to the wall never forward great separation airy highs beautiful mids. Overall a beautiful sounding cable. I've compared these cables with everything Entreq, Transparent, MIT, Nordost, Tara Labs, Siltech, Vera starr, Morrow Audio and some dollar for these are the best at this price range. Very realistic life like it's like being there. I have Silver and Copper RCA & XLR's 1m to 1.5 m available Free shipping in the States. Will ship world wide buyer picks up expenses.
