[quote=wrg2]Dave, don't really know how big a difference sonically the Sigs are to the Reference and for some it's not enough to justify the additional expense... ..Me personally, as I mentioned previously, just couldn't get past the Birdseye Maple finish. It fits in to my audion room decor perfectly.
I've posted quite a few times on this subject, there's been a lot of comparisons between the Sigs and Reference. Most of them conclude that the Sigs are better sonically. But the argument always centers around whether the difference is worth it financially. I was drawn to the Sigs from the Studios for aesthetic reasons as well. In comparing the two you can't dismiss the build quality and finish of these speakers.
I liken it to the difference between cheap furniture and high quality furniture, you can buy a dining room suite made out of pressboard for $1000, but how much more would you pay for a quality hardwood suite? Probably 10 times more.......
As to whether the cost difference is justified sonically, that's a tougher decision.
When I heard the Sigs in the showroom, I would of had to say no. But when I got them home and spent some time with them, in my room, with my gear, I quickly began to re-think that. If budget were no consideration I'd have to say that the sonic difference was definitely worth the price. If you're limited in your budget, you've got to do you homework. That is, take both home and try them out in your environment.
If you've already got a good sub, the difference in price between the Studio 100's and the Sig S4's is not that great and merits consideration. I easily prefer the S4's over my previous 100 v.2's. I can't comment on the v3 100's without having heard them.
