It's not heresy. And it will probably sound as well. All depends on your goal: if it is to eventually make your McMurdo to sing well, this is one thing, if it is also to show it off (not that there is anything wrong with it - it is a normal part of col'lecting things, to show them off) - you need the original or something close to it.

I respect either approach as long as it does not become a psychiatric issue.
