This is a tricky subject, as trying to future proof at the monent is fraught with danger, IMHO. Having read some opinions from the USA, it is liklely that Cloud based, hi res streaming will emerge in 2012. Distributors are in the process of releasing Hi res versions of their back catalogues and Apple are hinting at the future with their initial 256 kbps return of any low bit file 'beamed up'. No big deal for most, but if your whole ripped and otherwise i Tunes were to be available in Hi res, then that spells the beginning of end for the CD standard. As an interim, I've bought a Squeezebox and am very pleased with its performance as an internet radio source, but prefer the silver disc to streamed- the gap is not huge despite this budget streamer and its DAC. Paradiziac makes an important point about connections. Asynchronus USB removes clock duties from the PC, but not all DACs support this. Not all DACs support Apple lossless and have different max res for different inputs. Long USB connections are problematic. All a potential mine field at this stage. Potentially, the Pioneer LX85 with its 32bit DACs and jitter free HDMI connection to its new universal BluRay players is as future proof as it gets, but more reserch needed before I splash the cash.
