Indeed

I would've posted this in portable amps but since it is not portable, as it lacks a battery, im posting here instead.   Just wanted to let you guys know, that based on the information i have received, the model e10 is no longer in production.   What are your thoughts on this?

Hello guys, just wanted to ask what tip out of the ones that come with the vsd1/s do you like the most?   Regards

I was planning to grab an E10 either way Ill put more emphasis on this now

600 series, not sure with the specifics. floor stander

I do

I actually did some googling around and turns out the output impendance of it is 260 Ohms balanced, 130 Ohms unbalanced.
