TWISTED  Neutrino is the player! Every audiophile and music lover will like it. And the interface is just gorgeous. Finally we got the right replacement for iTunes.  
(Version 1.70)

DANIEL PAGE  I don't think that it supports the itunes sound check feature. I use iVolume to get all my albums playing at stable volumes (and boy, have modern alblums never sounded so bad)(Read about "Loudness Wars" if you don't know what I'm talking about), but audiocodex doesn't do anything for sound check, as far as I can tell,  
(Version 1.49)

MRCHIPS  I am in love with this app (don't tell my wife...:)! It isn't just the many ways Neutrino can manipulate the sound, or the iTunes integration, or video support, or the animations, or AU plug-in capability, or its ease of use. It is ALL that PLUS it is just gorgeous looking (PLEASE don't tell my wife!)...

I've used lots of audio apps over the years, many with some of the same audio capabilities, but for pure joy of use Neutrino has them all beat! I am amazed by the attention to detail I see in the interface, and it makes it all so easy to use .

Neutrino is the Scrivener of audio applications!

DJEFIS  Neutrino is simply fantastic, I had AudioCodex before and, for free, I received Neutrino.

Now I have two Player ....

I can say that, for something I like it more than iTunes.

Thanks to the Dev.

DOUGSTER  Version 1.30 (latest) is superb. I dumped iTunes ages ago in favour of AudioCodex. This software is amazing. To all reading this, do yourself a favour and try out this excellent audio player. It's the bee's knees!

I like it so much I would marry it tomorrow! Absolutely brilliant.  
(Version 1.3)

DOUGSTER  This must rate as the best player for the Mac.Not a fault with it. Brilliant! (Oh,MacLover, and here's another 5 stars to go with yours!).  
(Version 1.86)

MACLOVER1.1  Forgot to give it stars :-) Here they are !  
(Version 1.86)

MACLOVER1.1  This latest release does not crash :-) Sexiest player ever is back in my good books lol  
(Version 1.86)

MACLOVER1.1  Looks great.. seems to be quite versatile.. yet it gets miserably sluggish when accessing anything in its iTunes Browser section... if I try and load a track form there it seems to analyze its wave dospaly forever (to the point I force quit it a few times). When I read movies or music NOT form the iTunes browser everythong is fast and responsive.. dunno.. that is weird.

DOUGSTER  This update is superb. With AudioCodex around there really is no need for any other music player. What AC can do, others can't. Amazing.
