Like anything else here it will boil down to do you feel it WILL help, you may not hear a diffrence and it certainly wont be night and day....but maybe you will hear a better sound, or atleast think you do. I know guys that use Sony DVD players as transports and they sound awesome into a DAC.
If you have a "kick booty" DAC, does the transport
really matter as it is just a "reader" correct. Am I over simplifying it. When you plug your player into an outboard DAC don't it bypass the internal dac and stuff and shoot it to the outboard? Isn't the laser just reading the 1010101 on the disc and shooting the data to the DAC? If this is true can't a Joe just get a whatever player with coax/i.r./esbu out and just invest in a high horsepower DAC?
