if the cables are bad they will become a bottleneck and the sound quality will not improve at all.XLR cables are the core of the system so they are just as important as speaker cables and power cables.※ These cables are not at their best fresh from the factory so please make sure to break them in properly after the product arrives.I recommend about 50 hours of power-on time (the sound will improve significantly).[Self-introduction]The audio world is in the midst of a golden era where a sound that would have cost $70000 30 years ago can now be obtained for as little as $1500 to $2000. I carefully select products which have a sound quality that far exceeds their price tags such as studio-only limited modelspremium brand's failed products samples from manufacturers etc. and sell them at auctions. However the disparity between hits and misses is still significant and if you mistake a pile of junk for a hidden gem it can cost you dearly.Therefore I hope that users will make good use of my experience and connections to enjoy a rich audio life.
