| | 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?
