I've recently purchased the HD598 and i want to get a DAC/amp combo or two separate units to replace the fiio e7. I have to turn the e7 kindda high to be able to listen at good volume on the HD598 compare to the Triple fi 10. I'm thinking of getting the audioengine D1 because it has the usb and optical input. That'd be good for me cos i can use the PS3 with the D1 using the optical cable. I've also hear good thing about the schist magni and modi combo. Im using my macbook pro to listen to music. Any other suggestions are welcome.
1. budget ~$200
2. sound quality
4. size does not bother cos i'll be using it at home.
