I think I'll just see how it goes and buy if needed :P
Just need to wait for work to pay for the GS3 and happy days!
i'd say with the quads it just depends on the quality of the source more than the amplifier. idk how much difference the DACs have between the stock s3 in detail reveal. who knows how great the amp is in terms of muddying up the sound as well, so you might see an improvement, but I have little experience with portable gear so I wouldn't be able to say how much with any particular product besides the e7 which I owned for a short while. I think the e7 would be better than the stock DAC of the US galaxy anyway though. No idea about the wolfson.
