I think it really depends on how you see using your computer as server. Are you considering downloading hi-rez PCM files or DSD? If so, I would consider a stand alone DAC with DSD capabilities and continue to use your Arcam as transport for playing CDs.
I have stayed with CDs. Can buy far more music for same $$$. I use a Arcam DVD137 as transport and also have all CDs loaded on MAC mini. I play both through a Bryston BDA-1. I use the Audiophilleo2 for USB conversion as the USB input on the Bryston is not equal to SPDIF inputs.
