A few weeks ago Bulldogger mentioned his thoughts that using JRiver Media Center with the CBIV, set JRive to output 96-24 for all audio resolutions and bit rates, since the CBIV has 96-24 internal processing. His reasoning is that JRiver internally processes at 64 bits and has more computer power than the CBIV's processing so that should sound the best.
Bulldogger, I luv ya, but I think you are plainly wrong about this!
First, although you are very experienced with JRiver on a PC, you only recently got your CBIV, as you had sold your prior model as your family had been waiting some time to buy and move into your new home, so you really haven't had hardly any time to play with your media server PC & CBIV & Jriver.
Second, in the JRiver Wiki, for "Audiophiles" they recommend setting all sample & bit rates to "No Change" for those sample & bit rates that your DAC can process; and then
changing other sample & bit rates that your DAC can't process to lower rates that your DAC can process.
Third - I had been using the "No Change" on all sample and bit rates up to 192-24; and beyond that, I set DSD files for 176-24 and other files for 192-24. Sounded marvelous. Since Bulldogger's post a few weeks ago, I changed the sample and bit rates all to 96-24. Although this still sounded good, overall I "felt" my sonics at times lacking.
Fourth - Computer Audiophile has a raving review of the Schiit Audio Yggdrasil Multibit DAC Review at
The guiding force at Schiit is Mike Moffet, one of Theta Digital's founders many years ago. The article discusses the very importance of the digital filters custom designed with the Schitt DAC and that the characteristics of the original music file
remain despite the oversampling done by Schiit. Although Mike Moffet is long gone from Theta, Theta's DACs have their own custom designed digital filters with their own oversampling against designed to retain the characteristics of the original music file. By setting JRiver to output 96-24 for everything, you are downrezzing higher rez and upsampling lower res music files and essentially losing the most important characteristics of the original music file, except I would assume for 96-24 music files.
Fifth - last night I changed my JRiver settings back to how they had been all along, "No Change" for up to and including 192-24, and with DSD output at 176-24 (I had tried DSD at 88-24 and my impression that sometimes the 176-24 sounded a bit better so I left this at 176-24). And the result - once again in audio nirvana!
