Ouch, the Sony is a bit too expensive.
I'm dutch so my currency is euros, and I am able to spend a €200,- tops on an AMP. Cheaper would be nice.
I'm mainly buying one for the bass improvement, but I'm not very comfortable with pre-set bass boosts. I like the idea more of adjusting it myself.
And with those AMP's, will the iPhone put a digital signal to it (lightning connector), or do I input analog through 3,5 Jack, and let the AMP also process the sound?
