Turntables use constant angular velocity (as opposed to CDs, that use constant linear velocity).
Therefore, any "circular" groove of a record takes the same time to play, whether it's the first one after lead-in or the last one before lead-out. This arrangement has one main problem: the last groove(s) are much shorter than the first one(s), but still have to store the same amount of information (almost 2 seconds of music, for 33.3 RPM), which cause difficulties in the cutting and playback processes of treble (represented by a denser change in the groove geometry).
So, at least in theory, a higher number of RPM would offer better results, since any groove is only asked to store less info (just 1.33 seconds of music).
It's the same thing with a CD player; if the player has a CD-ROM drive running at four times the speed of a conventional CD drive, the bits should be more accurate (bit-perfect), meaning less data errors due to more amounts of data analysis of multiple read, and so better music reproduction. ...Generally.
There's no tonearm in a CD player, so no disadvantage from the beginning to the end of the laser reading.
In a turntable it is one of the reasons why some prefer a linear arm drive, just like when you cut the record.
And when you cut a record there are so many moving parts that they need to be perfectly in sync; not so easy to cut a perfect record.
And Open-Real tape decks too are high maintenance demanding reproducing tools.

I'm no expert, but for the general public I think that well made high-res quality audio downloads (music servers) are the 2014 way to go.
Less headaches, maintenance, moving parts, and speed's derivation. ...They also cost less in the long run.
And high-res audio files in a USB stick are easily portable. ...FLAC, WAV, DSD, DSF, WMA, ALAC, etc. ...24, 32, 64-bit/88, 96, 176, 192, 352, 384kHz.
...And asynchronous USB DAC, with jitter elimination.
Analog versus digital audio reproduction; it don't matter, what does is that you can't carry a turntable with you in your pocket, and that you're restricted to only two channels (stereo).
...And you can't carry a R-2-R tape deck either. ...Unless a mini Nagra one.

I've read articles before of people comparing various methodologies, and some high-end golden ears were mighty impressed by SACD,
to the point of finding a close relation with the master tape (indistinguishable).
SRV should also be awesome on SACD.

...I just don't know in comparison to those 200gr 45rpm LPs though, but to their CD counterparts they shine gold.
