and you definitely could make improvements by upgrading your cables I looked at the company and all they're using is copper but unfortunately it's not the best copper, The best copper for audio is OCC single crystal which is been proven now for over 50 years to be far superior to OFC which is what the company that you're using uses that's the cheapest wire out there and you're paying through the nose for cheap wire I can't believe when I saw the prices how big of a rip off this company is for using such cheap wire I think you should do your research a little bit better and you'll find out that OCC single crystal silver and copper is far Superior than what you're using now.
