Comparing the Nuforce HDP headphone output with the Little Dot MKIII tube amp used with HDP as a DAC, its obvious how completely horrible the amp inside the HDP is for T1's. I mean, it sounds disgustingly bad, and that's not even an over-exaggeration, I simply can't listen to it, that's how bad it sounds, I much prefer the old Sennheiser HD212 to T1 in that setup actually, its superior in every way, including detail and soundstage.
In comparison to MKIII, HDP + T1 sounds thin, lifeless, with no dynamics, poor extension in both way, and most importantly, the whole sound has a plasticky quality to it. Like listening to music trough a plastic cup. With MKIII its so much fuller, colorful, dynamic, sweet, soundstage increases massively, details pop out, music sounds real and natural, imaging is much better, its actually a somewhat holographic sound, you can actually imagine a real soundstage around you, etc. MKIII is only a 200 dollar entry level tube amp, I know, but it gives me an inside to what T1 can do with a great tube amp and makes me pretty much keep the headphone and not sell it, because that's the only thing I wanted to do since I first heard it. No wonder I was not impressed with the T1 so far only used out of the Nuforce...so, anyone planning to use the HDP and T1 together...don't, just don't. Save yourself the money and buy a DT990 or DT880 pro, it will sound much better.
