I've just installed the board and it's playing as I type :-)
Installation of the board was easy
- undo all the visible screws and slide out the chassis
- undo the two screws holding the USB board and lift vertically
- insert the new board and replace screws
ISSUES:
- the port switching button is one problem - it is not secure - to avoid this falling out apply a piece of tape on the outside of the case to hold the button in place.
- the led's are on long springy leads so their position has to be precise to locate them into the small holes in the case - it took a few tries but it is possible.
Other than that it was a breeze :-)
How does it sound - the top end definitely has more details, like cymbals, triangles, etc... and image has improved a little with improved separation, but I haven't noticed anything else so far - early days :-)
Was it worth the upgrade?
YES! If all you want to play is 176.4 hi-res tracks via USB
From an sonic improvement perspective...
If my Bifrost was being used to augment a "computer systems sound" (many are), then I might not have considered this upgrade - other than for the need to play 176.4 high res tunes.
By comparison - my Bifrost is part of...
- a modestly priced hi-fi system - around $12k
- it has an extremely good power cable attached to it
- it has extremely good Interconnects attached to it
- the USB cable is a dual cable design, one for Power and one for Signal, joined at the Bifrost USB plug.
- The power for the USB board comes from a separate USB power adapter.
- so it's tricked out to the max :-)
The high end improvement was immediately noticeable - so yes, in a system like this - it's definitely worth it!
If you have the Gungnir...
- I would have to believe it would be worth it sonically
- assuming you are using XLR IC's
- But again, make sure your cables are up to the task as well.
NOTE: If you are adding the USB in your Bifrost/Gungnir - then the installation has one additional step
- you have to add a couple of spacers that the USB board fastens to
- it's pretty simple though
Hope this satisfies everyone's curiosity :-)
BTW - my initial requirement was to play 96 and 192 high res - but it's nice to finally have 176.4 as well:-)
