I'm looking forward to demoing the S5 at some point...
Clipping issues aside, the Note 3 is definitely inferior (tonally, rather than technically) to the One M8, so - will be interesting to hear if the S5 is more like the M8 (let's call this 2014 'stock') or the Note 3 (which i'll call 2013 'stock')...
Damn, phones are more expensive than headphones to me... Have had in the past 12 months, HTC One M7, Xperia Z, Galaxy S4, Xperia Z1, Galaxy Note 3 , iPhone 5S, and now the HTC One M8...
