You
really didn't want to do this.
Better frequency response? Barely! Unless your needle is dull, a record (especially such a large-groove record as a 12" with only one song on each side!!) will have a frequency response that meets or exceeds that of the human ear.
Not quite, although this is a common myth. Sure, most records can easily reproduce 40 Hz to 20 kHz. It doesn't mean the frequency response curve is gonna be anywhere near linear. In fact, the curve is tweaked intentionally near the lower end to prevent the needle in the record player from shaking out of the groove! To make up for this roll off, RIAA equalization is applied to restore the original sound, amplifying turntable rumble and noise in this range.
Second, noticible warble is a sign of poor manufacture or player malfunction, so have that checked out.
Records warp just because of changes in temperature or humidity. This causes noticible warble over time, even with the best equipment.
And last (but not really last), noise is almost entirely dependent on the playing environment. Simply breathing while listening to music causes noise to the listener!
I'm talking about a higher noise floor inherent in the format. You obviously don't know what "noise" means in this context. I don't mean background noise. I mean static. I mean hiss. Electrical noise and noise from the imperfections of the needle itself in the case of records.
And, when it comes down to it, a record can be played without the need of electricity whatsoever, whether piped in from a utility company or generated on the spot.
And I have a discman that plays for 40 hours with two AA batteries. Who really cares about independence from the power company? I'd rather have fidelity over the ability to listen without electricity.
And finally, though this particular record is an exception, 12" covers offer a much better opportunity for artwork appreciation than the little 5½" cover sheet on a CD. 
Does that make up for the crappy sound reproduction inherent in the format?
