Since they are so often conflated, we seem to need to distinguish between the needs of the people who produce the media which are social, and the capabilities of the media itself which are technical. At the physical media level, audio CDs have 20-30 dB or more dynamic range then vinyl is capable of. That is basically why vinyl was almost totally blown off the marketplace by the CD. > > There are such things as dynamic range expanders (what limited use they > have is for de-compressing compressed waveforms ... but that happens to > be what we're talking about!) > Dynamic range expanders were thought to be helpful when vinyl and analog tape were all we had. The CD eliminated their technical justification.

It existed (note past tense} This web page says it all: http://dbxpro.com/en-US/products/1bx-series-iii: "Discontinued" Secondly, it wasn't a consumer product when it existed - it and devices like it were found to be too complex to appeal to general consumer. > > It can come to pass. > It came, it saw, and it was conquered. You've misrepresented the device pretty thoroughly, whether intentional or not;. DBTs have shown that a single generation of vinyl transcription is highly audible while a single generation of even mediocre but modern digital is sonically transparent. Don't forget that High Fidelity = sonic accuracy and transparency. ------------------------------------------------------------------------ arnyk's Profile: http://forums.slimdevices.com/member.php?userid=64365 View this thread: http://forums.slimdevices.com/showthread.php?t=105070 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
