I'm very excited about this new DAC and the price point seems to be quite reasonable for the performance it will offer.
I'm still not too clear about the jumper for ultra high rez. One setting (up to 24/96) means that no up sampling will take place and files that are 16/44 (or anything lower than 24/96) will be processed as such. The other jumper setting means you can process up to 24/192 but any input with a lower rez will be up sampled to 24/192. Is this the case?
If that is the case, some sort of routing for an external jumper as Wayner suggested would be of great use. There are already sources for high-rez downloads and I already have 24/192 files although not many at this time. They will likely become more popular.
If the jumper setting is set to 24/96, how will the Vision DAC handle 24/192 and 24/176.4 files? Will they be down converted to 24/96 or 24/88.2?
Still if a switch on the back can be rigged to act as a jumper, that would just offer more flexibility.
Here is the link on Wolfson's website for the 8742 and to the datasheet.
http://www.wolfsonmicro.com/products/WM8742http://www.wolfsonmicro.com/uploads/documents/en/WM8742_Rev4.2.pdfIt has some interesting features including DSD (I2S, RJ, LJ, DSP, DSD). Does that mean it can handle SACDs? I know you would need a special connector to pull that off (probably something like I2S), mainly because digital coax is limited by record companies to lower bit rates for copy protection reasons. An I2S connection could also work great for audio sources from Blu-Ray Audio discs. A good example would be the Neil Young Archives Blu-Ray box set and many other concert Blu-Ray discs. It would be nice to feed the digital output from my Blu-Ray player into the AVA Vision DAC.
I hope you guys can clear up my questions.
Either way, I look forward to hearing opinions on the improvements the Vision DAC provides compared to previous models.
