I think this has been discussed in the other Modwright 105 thread. Briefly, any NOS 6SN7's may be microphonic, they are old tubes even if they have never been used. However, yours are the first microphonic Sophias I've heard of, and I would complain to Sophia.
Brent Jessee, like all the reputable NOS tube dealers, will take the tubes back within his exchange period. He can suggest some tubes that are less likely to be microphonic, like the 5692 series and the Raytheons with the extra support rods. He tests for microphonics, pretty much all the better dealers do, but some of these old tubes can go microphonic during the shipping process.
Tube dampers are another issue. Many feel that using them on preamp tubes like the 6SN7 robs the sound of "life". FWIW Brent sels some very simple teflon rings that damp a bit (way less than Herbie's) without seeming to otherwise affect the sound.
Last, the Oppo, with all its moving parts in close proximity to the tubes, is clearly a worst case scenario for microphonics. I don't think airborne vibrations are within orders of magnitude of the mechanical vibrations of the drawer and disc drive. Nevetheless, many users have been able to find good sounding NOS tubes that have little enough (or no) microphonics to be acceptable. I would suggest continuing to try, and don't put too much emphasis on the specific dealer if they are reputable and have a good exchange policy.
