I have been a fan of Denon for many years and this app is great for anyone who wants to enhance their musical experience. The menu system is very straightforward. I purchased the IAP and although I havent used the pro features yet like the one-3rd octave and the 10 band EQ I have been using Denons signature EQ setting. That alone is worth the price of the IAP IMO. I also turned off the limiter and raised the attenuation to normal or 0.0db and there is no distortion. Add in the radio from countries around the world that include death/black metal which I like as well as other types of music and I think this app is a pretty sweet deal. My only complaint would be that it doesnt support hi-res audio. Another well known company has an app in the App Store that has hi-res audio so it can be done. I really hope Denon considers making an update to include hi-res audio. Otherwise great job Denon.
