Been lurking around these forums and learned quite a bit. But now I want some opinions on amping the HD650s. I currently already have the HD650s and FiiO E17+E90K, but now want something better. Looking to sell the E17+E90K to fund the next equipment. I have a budget of about $1000. I also have a Arcam rDac powering my speakers, so I could use that as a DAC, but am open to buying another DAC as well. I have listened to the Schiit Asgard + Lyr and they sound amazing compared to the FiiOs, so those are what I'm learning towards.
