Selling my Meier Corda Soul, which I ended up buying again after selling my first one, but it's time to let it go to make more space.
It's been used in a professional setting, so it has some marks of usage, that said, it's nothing major and it's just paint, no deep marks or anything, but the price is ( relatively ) low because of that. In terms of function it's 100% perfect.

An absolute TOTL dac/hp amp/preamp, with enough power to drive the great majority of headphones in the market and incredible flexibility thanks to the options for EQ and crossfeed, and also thanks to the multiple input options.
The sound that it produces is incredibly transparent and detailed, it doesn't have much of a particular wow factor but it adapts to every headphone easly.

For any questions feel free to ask, I'm always available

( For trades, I'm mainly looking for closed backs and iems, but feel free to propose anything ! )

I'll leave here the link to the page with more technical descriptions for anyone interested:
