The DI with upgrade is $3300 The SE is $6500.
To add to what @waltersalas and others have already shared, consider the following:
If your budget is tight then go with the DIs.
If your budget does allow for the extra spend on SEs but there are other components you can (and want to) upgrade or add, then use the extra $3200 towards that, and go with the DIs.
If you feel your current system is more ’basic’ in nature and you don’t want to upgrade your gear, then go with the DIs.
If you keep your gear for a long time and foresee yourself keeping whichever speaker you choose for the long run, consider going with the SEs.
If aesthetics are a priority, rather than incur the added spend on the DIs, I’d suggest stretching your budget to get the SEs (as the price includes the custom automotive paint finish).
If exit strategy is a priority, then go with the DIs as they fall within a price range that many many more folks are comfortable with and they will be easier to move.
If your listening mostly includes genres or artists that are not as well recorded, go with the DIs.
Making these points as an add on to the already great feedback you are receiving. Hopefully they are helpful.
All the best.
