I use two SB3s with one in my main 2 channel system feeding the Wadia 781i digital input. In addition to the SB3, Duet or other remote options you can also use the SlimServer software in your PC, Macbook or laptop as your remote control. This is very convenient when using your computer while listening to your ripped music, itunes, internet radio, Pandora or other music sources through the SB3. It's also easy to control volume from the computer if desired.
With the Wadia as my DAC the sound of CDs ripped to FLAC is as good (sometimes better) as Redbook CDs played direct. Both are through the Wadia. However, SACD is still king with this system. This is saying a lot for an audio component (SB3) that cost only $300.
I'm eager for Logitech to release the new 24/96 capable boxes soon. Will a new 24/96 Squeezbox then equal or surpass SACD sound quality played through the Wadia? I'm waiting for Logitech to make them available so I can find out.
However, Wadia now has a USB Upgrade available for the 381, 581 and 781 models. Perhaps, I can go direct from laptop to my Wadia with a higher rez option. If so, then I'll be sending in my CD player for a USB digital input upgrade ASAP. Can you use SlimServer to output 24/96 from a computer? If not, then what software and Operating System would I need for that? I'm currently using a MAC.
