Hi everyone!
 
I have been using my ES10 / ES535 for commute with my Iphone 6 for a while now and have always wanted to experiment adding an external amp to see if there would be a significant improvement in sound quality. Having said that, I must confess that I use Spotify (rnb / pop etc) for all my music with the iPhone and that will probably affect the usefulness of the external amp. 
 
Portability is a big factor and I'm looking into the Resonessence Herus.
 
Any opinion on this?
 
Your help and feedback is much appreciated. Thank you in advance.
James

I had an ES10 and was using it straight out of my LG G3 for a while and it sounds great that way. I had another ES10 a while back and used it with my iPhone 5 and Fiio E12 and it sounded great that way too. When I added the ALO The International into the chain out of my LG G3 I actually found that it didn't sound quite as good as without the amp (odd). It gave them a low-end bloat it seemed. I don't use the USB line out, just the basic 3.5mm jack on my phones. So personally I didn't use them with an amp. I never tried them with a DAC, so maybe that was my problem. This is just my experience though. I believe a portable set up should be as basic as possible. I currently use an SD-3 right out of the G3.

The iPhone's built in amp tends to be weaker than those on Android devices though, which is why Apple wants to do away with the 3.5mm jack.
