FiiO E5 amp (E3 upgraded)

I personally don't really see the point to that. The PK3's, like my OK2's, are driven easily by the HP out, and need no further amplification. If you do, you'd just amplify whatever is coming out of that HP out. It really is best paired with an LOD so you get cleaner sound, and not having double-amped sound. I think it works great with an LOD and my OK2's though, sounds better and although the OK2 are easily driven, the E5 also doubles as a more convenient volume control.

Just got an e5 and am extremely pleased with it. It's made a huge improvement to both my walkman phone with S-Jays and the passive mode on my Goldring NS1000. I reckon if I'd bought this last month it would have saved me about £90 (for MP3 player, CMOY and a set of headphones). Superb for the price.

I have a Iriver H320(FLAC) driving the Shure E5's.
Do you guys think the Fiio E5 will enhance the sound or should I save the money and go for something better(read more expensive)

Yes, the headphone jack on mine went bad after about two months. I sent it back for warranty replacement.

Not likely. The power amp section uses TPA6130A, which I believe is in QFN package and not compatible with DIP-8 / SO-8 package (that OPA2134 comes in). As for the preamp, it probably doesn't have enough juice to power OPA2134 since the original opamp (OPA2338UA) operates on very low voltage.
