I'm currently saving some money for a good DAC and amp I can use with a couple headphones. I currently have a Beyer DT 880, Shure SRH 940, and I'm planning on getting the HD 650 soon. I'm kind of new to all this, so I don't have much experience with amps and DACs. In another forum I posted about a Nakamichi CD player and Amp from the late 80s that I have been having fun with, and it actually sounds pretty good, but I know that modern equipment will outperform it. I looked at the Schiit Bifrost and Lyr, or maybe I could upgrade and get the Mjolnir and Gungnir. I'm not terribly interested in getting a tube amp, cause you have to replace the tubes every once and a while, so something solid state. Right now, my budget is up to around 1.5 K, what would you guys suggest? I would be connecting directly from my laptop via USB, or sometimes from a CD player optical.
