Sorry to bother anyone, I appreciate everyones input here, but I've decided to wait it out and spend a bit more towards and get a DACMagic instead, although, I'm having a hard time thinking on what I should upgrade in my proposed headphone rig.
DAC: Cambridge Audio DACMagic
HEADPHONES: Denon D2000
AMP: Audio Gd C2C
CABLES: From Blue Jean Cables
If I had an extra $300 to spend, what should I upgrade. I usually listen to mostly 200kb-320kb LAME encoded MP3 and FLAC files and will be using my computer as source with foobar2000 + WASAPI and I want an amp that will be able to drive the Denon D2000's and other headphones I'm thinking of getting (AKG K701, Sennheiser HD650, Beyerdynamic DT770, Ultrasone Pro900 etc) with good clean power, I will 95% of the time be listening at normal listening levels. I want to stick with Solid State just to be on the safe side, as I'm unsure of how tubes sound and if I will like them as I listen to a lot of Electronic Music (Dubstep, Drum and Bass) and Hip Hop.
I would like to stick with Audio GD if possible and I would like to go balanced, but that's just optional.
Should I upgrade the DACMagic or the C2C, or something else in my proposed rig? I like how the Audio GD Roc has a Balanced Headphone input and can go Balanced. Although I'm not too keen on changing the headphone cables to balanced ones.
I hope it's ok for me to ask this in this section.
Any input is much appreciated.
