Here's a comparison of the S6 and S5:
The ear piercing highs a more tamed in the S5 compared to S6 and tolerable. Although it still has more treble than the Note 3 and S4, there's also more warmth than the S6 and the upper lows and lower mids are much more present so you get larger, warmer bass. The mac mini 2012 does a better job than any of these, with very smooth mids, lows and no piercing highs. I think I'll stick with the S5 for now. Apparently Samsung thinks upping the treble and screaming vocals are considered better sound. The highs are getting more and more pronounced from S4, to Note 3, S5 and then S6.
Also, a note about the display color. The S5, like the S4 and Note 3, has darker deeper more saturated reds and a warmer display. This is more pleasing to the eye and I think the S6 took away some of the magic of the AMOLED by making the colors brighter and less saturated. In a store with bright lights, you could probably fool somebody by telling them the S6 is a new type of IPS LCD.
Sounds like I'll just keep my S5. I love the removable and upgradable memory, and I don't mind the plastics of the phone. I don't need to spend $1000+ CAD to get 128Gb of memory, so I can take my music collection with me on a phone that doesn't sound like it's better than my already loved S5. Thanks for the comparo.
