The danger is always using your current system as the most reliable measuring stick there is...it may not be...and if it isn’t (a Lot more likely than you might think), then when will it ever be, if at all. How ya gonna know if you’re making the right comparisons if the rig you’re comparing them on is lacking something, tangible or otherwise??
Some music reviewers have admitted falling into this trap before, JG Holt among them.
I have lots of originals and remasters of the same title. Me?? I never throw away a disc...today’s preference of remaster to original, or vice versa, might not be tomorrow’s after an upgrade.
