how to fit the burson (dual) v5i opamp in xonar hdav or xonar stx sound card
here's how it fits ....just
pardon the detail, but this is included for the benefit of those who may not have done this previously
a reminder that you need the
burson v5i dual opamp for this situation, or any other dual opamp you might choose that is compatible with the specs required
please note that you modify your card at your own risk; my enthusiasm to have you enjoy an upgrade needs to be weighed against your potential disappointment if you somehow nuke your previously lovely sound card
that would be sad, but it won't be my fault, will it ? so as long as we have that understanding...
i presume anyone rocking a xonar is familiar with pci-e slots and fitting cards, but if not, get some assistance or do some reading
as always, you need to power down and safely remove the xonar, noting the ancillary molex needs to be unplugged too - take the usual precautions re static discharge
undo the 4 small screws holding the cover / faraday cage, noting that they can strip their mounting holes easily, and you may need traction on the cover to make them screw out easily - gently but firmly does it
and put them somewhere safe - not just on the bench, from where they will migrate mysteriously to your utter frustration at the end of replacing the opamp; a small bowl or equivalent is fine
okay, ready for the rather simple but slightly more nerve wracking part if you are new to this :
take your hdav 1.3 (or an stx), noting the "blue" dual opa627 is in the buffer socket - easier to see the colour in the closer view
the original amp supplied in that spot is marked (LM)4562NA
yep, that's it there, with all those white things labelled "8n2 100" snuggling up cosy
you need to pull it out - purists have a tool, but i have fingers which do fine with the dual opa627; but i think i recall using a bios chip puller for assistance when i took out the original buffer amp, as it hasn't got the same lip to grasp, a small screwdriver or a spudger will help - a thin guitar pick is good
if you choose a screwdriver, don't slip and gouge the traces or the only sounds you'll hear thereafter may be profanity
the v5i is marginally less high above the socket than the opa627 is when seated, but it's definitely wider
trying to get it to fit between those white protrusions takes a little persistence
looking "along" the socket you will note the slight slant you'll need to impose on the components
they move pretty easily with a firm grip, courage and one gentle tweak... but i suggest you shouldn't wiggle them lest you break their legs
and in goes the v5i, taking note of the notch under the v5i to confirm orientation with the notch of the socket (facing the camera, as easily seen in the photo above)
even though the opamp looks uneven below, it seems quite firm and refuses to sit under the level of the right sided components - it is however quite properly seated
i have now replaced the buffer in both my xonar hdav cards with the v5i - both fit as shown, and most importantly, both are working fine despite the minor apparent asymmetry - closer inspection above (and below) reveals that the vertical obstruction is marginally closer on the side nearer the pci-e connectors
don't forget to screw back on the cover / faraday cage before you re-mount the card in your computer, and also to plug back in the molex and your rca's
then boot up, sit back, and enjoy your new improved audio experience
hope that helps instil confidence, because apart from the minor jostling for seating space, it's an easy job
