Suggestions for Digital Audio Recorder

I'm looking for a standalone digital audio recorder device, either home or portable, that has analog inputs and outputs, as well as digital inputs and outputs.  Some thing that can record at CD quality and higher resolution, with built in memory storage or SD card slots.  Thank you. 



I have a Tascam DA-3000 and it is a great unit, capable of recording up to 24/192 and DSD 5.6. Unfortunately it has now been discontinued. Grab one if you can find one!

I use the Tascam DA-3000 to record DSD128.  It can also be used to record the output of another A/D converter.
