Pre amp outputs
#4
More of a marketing gimmick, than anything else... Larger digits make some people feel warm and fuzzy. I think they have a pill for that now. More expensive units have better internals, which is attributed to main differences in quality, not preout voltage.

Hear it goes...
preouts are measured from 20hz-20k hz, manufactures use the highest peak voltage of preout voltage as their rating. For example 2 volts @ 400hz. If you look in the back of every manual Panasonic, Sony whatever, it will have its highest rating @ xx hz. But they do not tell you that at 100 hz it might be .5 volts! That is why you hear a difference, you might have a mid-bass hole in your system because a head unit might only have .1 volts at 400 hz. While a different brand might have 2 volts at 400hz...hence making it some better. Some companies like Eclipse rate their preouts from 20hz-20k hz instead of only one frencency. Eclipse has always sounded better because of this, no other manufacturer will state their rating from 20hz - 20k hz. That is why preout voltage is better, but not all preout voltage is the same. My opinion (which I have tested)
1 - eclipse
2 - pioneer
3 - JVC
4 - Alpine (3 years or older will places them in second)
4 - Sony
5 - Panasonic (the absolute worst in the sub range!)
This is all I have tested...
Or
Add the good quailty line-driver and solve all the issues. Keep in mind some amps cannot take a high voltage preout in...but that is another topic.
Cheers!
