Was there anything V281 did better then HDV820 you think? Did you have the most expensive volume pot (+ 589$) for V281, they claim it makes a difference in sound.Yes, I would have the same conclusions. Most of my opinions were based on using a Chord 2Qute which was much better then then the Violectric DAC cards. Would say the bass was the same between Violectric and HDV 820. Very controlled because of the power and when running with a balanced cable, you'll have more bass control and hear more of the environment/recording space. I'm now running a Invicta Mirus with my HDV 820/HD800S.
The HD800S headphones are not known to be bass heavy but is you want to get the most bass out of them, I think Violectric and the HDV820 would be good choices.
The only fear i can have against HDV 820 is that it might be to polite and smooth and cant rock out and engage.Am i wrong?
