I'm selling my MF V-DAC which i used for USB input from laptop, coax digital from a Blu-ray player and optical from Airport Express. I still have a Little Dot_DAC II which has all 3 digital inputs and will be connected to one of the inputs on the DEQ 2496.
I'll use the digital input on the 2496 for a CDP and use the LD DAC for what I mention above...lots of gear connected in my chain.
I do want to experiment with the RTA function but my only mic is an Alesis and I don't know if it will do the job, as far as being accurate/flat. I haven't tried it yet.
I also like having the PEQ and GEQ for tweaking the sound of each CD on the fly, for HP and speakers. I use my Woo 3 tube amp as preamp for speakers which adds a nice flavor to my B&Ws.
