I agree with Charles. I have heard those two side by side at a store when a customer was in with the Schitt to hear the differences. I listened via the Audeze LCD-3's, which I enjoy and know well. I found the Codex to be more accurate, better staging and imaging. I feel that listening with can's give you a great idea of detail, both micro and macro, but not as good at sound staging. I'm very very surprised the Codex got so hot. I'm in shock actually. Did you ask the dealer about this? I've used the Codex well in excess of 20 times at many dealers as well as in friends systems. I have many who own one and not one have said they run THAT hot. Not taking anything away from the Schitt as I know there are many who love the company. I always enjoyed their designers products when they were with their other companies years ago, so again not taking anything away from them. To my ears the Codex is the best under 5k or so DAC I've listened to and I"ve heard many of them out here. Again, JMHO and that's why there are so many companies who are making equipment. We all listen for different things and all equipment reacts differently with other gear. How many times have we listened to something and loved it, but got it in our systems and it just didn't work?
This is why Matt always talks about what's in HIS system when he reviews for everyone. There have been so many DAC's sold because of this thread and they aren't all Empirical as Matt has loved (I bought one and loved it).
