I'll probably keep my SBs until they are ready for the audio gear graveyard, which could well be for a while. Everything still works great. I have started to research and experiment with alternate, broader A/V technologies, mainly XBMC running on Android media devices. Usability features continue to improve and may be the ultimate draw to another platform. As long as I am running an external DAC with a good digital connection from source, I am not too concerned at this point about sound quality of devices geared towards a broader market than the very small niche high end audio market.
