@Almarg
a nice side benefit of my present preference for a one-box player is that I don't have to concern myself with jitter issues.
Are you saying cd players don't suffer from jitter just because they are cd players?
The CD player is dead.......
Now today for example, it was very nice listening to Mozart piano sonatas and then adding the Beethoven Pastoral Symphony while sitting in my chair in my bigger listening room and not having to get up and go into the next room to change things. I use the VisualMR program on a Windows PDA with a wireless connection to control my Rokus (one on each of two systems on different floors that connect to a shared music server laptop to select songs or entire albums from any room in the house. Now that is sweet and something I could never have even dreamed of before! |
Are you saying cd players don't suffer from jitter just because they are cd players?A well designed cd player will have jitter issues that lie somewhere between minimal and none, because the relevant clocks are generated internally and are only transmitted internally, over very short distances. A two-box approach, whether the interface is usb, s/pdif, or aes/ebu, faces the fundamental issue that data is transmitted to the dac synchronously to a clock that is generated in the source component, not the dac. That creates huge opportunities for jitter to be introduced, due to impedance mismatches, cable issues, noise issues, clock recovery and synchronization issues, and a host of other possible ways for things to go wrong. Certainly those issues can be successfully overcome, but its nice to not have to worry about them, or to invest time and money in optimizing them. See for example this excellent Ayre white paper, for an overview of some of the complexities involved in adequately dealing with the jitter that can be introduced in a usb-to-dac interface: http://www.ayre.com/pdf/Ayre_USB_DAC_White_Paper.pdf Regards, -- Al |
