Question CD signal-to-noise ratio question

I'm looking at getting a decent head unit for my E30, since the previous one was stolen while at the shop. The owner gave me a replacement, but it doesn't have a brand name anywhere, no spec sheet or anything, so I figured I'd just get one I picked out.

I have a few choices, ranging from $100 to $200, and the Pioneer DEH-P3800MP is looking good with features I like, but it has a lower signal to noise ratio (94 dB) compared with some other choices (100-105 dB). I'm relatively new to the audio scene, so I'm wondering: How big of a difference is that 6 dB difference in the S/N ratio going to be?

If it will be a deal-breaker, is there a way to improve the S/N ratio?

Thanks

There isnt any way to improve the S/N ratio. Thats something is done at the factory. You probably wont notice a 6db difference though. In that price range take a gander at the Premier (Pioneer's pro line) DEH-P380MP (should be that number, their site is down right now). Its usually not 20-30 more than the pioneer equivalent and you get a two year warranty plus a features that the standard line doesnt have. Good luck with your purchase...

polaris448 is an unknown quantity at this point
if you are an audiofile and you want to hear notes reproduced that you have never heard before go with the higher s/n ratio. it not just the s/n though. usually if a HU has a higher s/n than i has to have better processing to handle the more definition and that will equal a better deck. i am a true believer of alpine for sound and durability.
