For the last few weeks I've been looking into various DAP's and I'm very tempted to purchase the Colorfly C4.
Some background info:
I currently have a Onkyo NS-D1 dock that I use for direct digital output from an iPod into a DacMagic.
My headphone amp is a Project Headbox II, and my cans are Sennheiser HD-650's.
I've been wanting to find a similar quality portable version of what I currently have, hence my interest in a colorfly c4.
However, (and this is really my main question) the majority of my music material is basically apple mp4 256kbps files.
Would there be any real benefit in getting a colorfly c4 (paired with my HD650's) when just using the apple 256kps audio files I have?
Or would I really need to consider re-ripping my cd's to FLAC before even considering a unit such as the colorfly c4 for it to be of any real investment?
Apologise if the above doesn't make sense, but in summary I guess I'm just trying to understand whether it's a worthwhile proposition given that I have no hires type of music material. Should I only consider such an item for FLAC / hires types of audio file?
