I posted this at another site when I was performing a test for me and some friends to see if we could discern the differences in the various outputs from my Oppo to
my new Bimby:
"So now that I have this Bimby and have conversed in other sits on the merits of PCM, FLAC, via Digital, coax and optical vs PC USB2.0...I put together my
in-home test and invited several people over to test them!!
(I like these real world sessions where we discuss the merits of each and then "listen" with knowing what the sources are and then I do a Blind test with the group and see if they really can hear what they are talking about!
Well hooked up to my Oppo modified old BD 83 Special Edition, I had both digital outputs going into the Bimby and a USB to a PC with Flac files.
Once I got them synched up the fun started....
With the switch on the front of the bimby it was easy to switch quickly between the three.
The results were interesting:
At first when one listened for 30 seconds or so I switched to the next source input...most all immediately said "the other one" real fast....but then after 30 seconds or so it was harder for anyone to tell good or bad.
When someone said the other one I hid the selection switch and moved around and even set them up by saying it was this one right...and they said "Yes!" but then I told them it was not the one etc....more smiles..
Then end result of a nice Glass Optical digital cable, a great Coax digital cable and a good quality well known USB cable to a "noisy" PC with all its RFI, digital clocks spewing out RF etc....was that no-one could reliably tell the difference in any of the three.
Mike Moffet at Schiit prefers PCM to Digital out etc....and I understand the technical reasons etc...but in my real world its really close..and to most a "dont care".
But its fun to play and test and have a few laughs...
Next we will do the same with a bunch of dacs and see if "bimby" works as well as I think it "sounds"..
All the best
