I was quite taken aback by the sound quality actually, having never heard of them prior to that day. Seems criminal to me that these are not better known here at Head-Fi, although I see recently they have been impressing people at some meets - a lot people declaring the HD800 pairing with them single-ended the best they've heard the HD800 (and even best in show for some of those people).

 

You might be able to answer a question for me here, by the by. I presume I can connect them to the Vega single-ended and balanced, and switch between the two inputs and outputs with a flick of the switch? Will be nice to be able to compare say the HD800 SE to the HE-6 and Ether balanced with very little delay.

Hmmmm.... I want to say I think that would work. I'm sure I've tried it at some point.

 

The only thing to watch out for would be volume control. You spend a lot of time matching each channel just right in monoblock mode, and then for SE mode you'll probably end up adjusting one of them. So you'd have to match again with each switch. Unless you max them out for monoblock mode and control volume with your DAC - in which case you'll still have to mess with volume for SE mode, but it won't be as particular.

Yes, I had thought about the volume control. My plan, at least initially, was to max them and control volume from the Vega. From memory there isn't bit loss/truncation until you get to around 60, so hopefully that'll be enough volume attenuation (more than likely will be for the HE-6, perhaps not others) but I'll have to look that up to confirm.
