I wanted to make LR channel balance becoz my left ear cannot hear well... What do you think? Will this work? This will need 2 fiio E5 Can fiio E5 accept mono plug? It wont short circuit or anything? Will this degrade the SQ tremendously? I know i can use a logarithmic taper instead but...

So what is the different in both DSP? Pros and cons. Which one have better SQ? Also if someone can recommend me the most commonly used impulse reponses and VST plugin among thousand out there. Links or names searchable by google are welcomed. Particularly, I'm looking for the best to do reverb...
