VibrumThe first version of the Schiit Vali is on sale for 99 dollars on their site. That's a really nice amp for the price and paired quite well with my modded sr80i's when I had them. Then ringing problem was annoying if the amp was touched, or even when the switch was flipped.
VibrumI haven't heard the Little Dot 1+ myself so I can't give you an honest opinion. From what I read online about the little dot, it pairs with grados better and it has more options due to tube rolling, I would lean towards the little dot 1+ myself. Sorry I can't be of more help!
