@ paulcreed, I believe auxinput nailed it on the head with this, quote- In the end, I think it depends on how much resolution the system has. If you are working with a very warm sounding system, these burn-in exercises may not affect you quite as much. However, with a very revealing system, you could be in for a long term burn-in experience. Though, Rhodium is the way to go if you want the best in resolution. Personally I run my tube/solid state hybrid digital player with a $5,500.00 power cord that has oyaida plugs on it straight to the amplifier, so yes, absolutely, it has to do with resolution of any given system.
