Cambridge 840C Azur through a Bryston BDA-1 DAC?

Hi Folks,

I currently have the Cambridge player, and like it very much. I'm running it through a Bryston BP26p pre w/ phono stage and a Bryston 3BSST amp, Acoustic Zen speaker cables and XLR interconnects, and a pair of Daly Euphonia Mk 5 speakers. I do not currently have a DAC in the system, but having been reading all the raves about the new BDA-1, and am wondering if it's worth the investment, given the fairly well-regarded DAC capabilities inherent in the Cambridge. Would this be gilding the lily / a waste of $$$ (minimal ROI), or a great way to go? And if the latter, what does everyone recommend in terms of an optimal interconnect (from DAC to pre)? I've been looking at the Green Hornet SPDIF, but am open to suggestions.

Any thoughts will be greatly appreciated. BTW, I'm still a few years out from taking the server plunge, but am resigned to integrating one at some point, when I know this DAC would be more of a necessity. For now, I'm mostly interested in getting a sense of how much it will really do to improve CD playback, given my current transport. cheers!
