Not at all. The size of the buffer has nothing to do with the quality of the burns. The only thing a larger buffer does is provide more of a margin against buffer underruns. That used to be extremely important before buffer underrun protection technology was perfected, because without such technology a buffer underrun meant a wasted coaster. In that sense, yes, the size of the buffer used to affect the quality of the burn - it had the possibility of preventing an unreadable disc. But now a buffer underrun is but a delay in the burning process.
Also, although CD burning speeds have increased, so have computer speeds. My system is none too powerful (1 GHz Pentium III), but it has no trouble keeping the buffer 95% full or more while burning at 48x. I've never come anywhere near a buffer underrun that needed to be prevented/corrected by buffer underrun prevention technology, even though my drive has only a 2 MiByte cache. So, 2 MiByte is sufficient even without buffer underrun prevention technology, although, of course, I wouldn't burn without it.
