I was incredibly lucky to be gifted a pair of Sennheiser HD 800s for my birthday. I currently am running the 800s with my Earmax Pro and a Sony SCD CE595. I am looking for a portable DAC that would pair well with the Earmax and the Sennheisers. I am new to the whole dedicated DAC and also could use an explanation of how to rip all of my CDs. I am wondering what the quality difference will be with a cd rip on my MacBook + DAC vs my Sony. Any and all responses would be greatly appreciated!
