Well, in my case - based on my experience, the situation recommended for you would be as follows:
1) Purchase the Schiit Magni amplifier. It is a solid piece. It performs well. It is very good for the cost.
2) Purchase the Muse Mini DAC, which is based on the Burr-Brown PCM 2704 chip. It features the option of accepting a USB input. It can also convert the USB to an optical or digital COAX signal if you have a future DAC or combo that may require a digital input to play music that is higher than 16-bit tracks.
Cost: At the moment, the costs would be approximately $130.00, for both pieces and before shipping. This would mean that you would have a powerful amp to drive a potential future Audeze purchase, as well as some flexibility on the DAC end, and have a DAC that has a reasonable / good house sound that Burr-Brown is known for.
PayPal Payment: No need to send me a $1.00. Please feel free to donate it to your local charity instead.
On the DAC part, I currently own the Bifrost. I use a standard USB AB cable to connect the laptop to the DAC. Is there/Can you recommend a better cable/accessory that will connect the USB out of the laptop to say the optical in on the DAC ?
