I'm in for a difficult choice, I recently bought a Meridian Explorer 2 to work as a portable amp/dac for my laptop. I would also want to buy a desktop amp mostly to drive my HD650's. I recently visited an audio store close to my home and they told me they have a returned Lehmann Linear Black Cube on sale for just 550e, I had previously been considering the Schiit Asgard 2 which shipped to my home would be around 260e. I'm thinking whether the Lehmann would truly be worth it since I already have a DAC. Would the amplification difference be that large? Thanks in advance!
