I don't understand why you would not encourage the poster to properly treat his room before assuming that his equipment and/or vibration is the source of the excess bass. What if the previous 'table was bass-shy and that effect was masked by the room?I would say he really needs to make sure his room is reasonably neutral before he actually knows what his gear really sounds like. Given the context of his post, it seems his room response is a big variable at this time - it may be reasonable, it may be poor, but it is currently unknown. A couple tube traps in the front corners of the roon will certainly do no harm.
I won't argue that implementing vibration management is never a mistake and something everyone should take advantage of. I'm sure you guys wouldn't argue that no amount of vibration management or component upgrades will effectively solve a room response problem.

Pete,I read the original post as indicating a change from an LP12 to the Pink Triangle. There is a spring suspension on the LP12 and I think the Pink Triangle has a more rigid suspension. Given reasonable setup on the LP12, and given that both turntables are more than reasonable and that the cartridges are likely to be equivalent and quite good to go with the turntables, my feeling was that it was more likely that vibration was a problem. I doubt there is enough difference in the bottom end of either, given good setup, to change things so that sound is boomy due to the room with one turntable and not with the other.
Given that the boom arose with a turntable change, I think it makes sense to eliminate that change as the actual issue before doing anything else. The room is a constant in both situations.
Yes, bass trapping will help anyway, and may even yield an acceptable result, but if vibration is the issue then I think that dealing with that first will yield a better result than bass traps on their own would.
Note that I did leave things open about installing the bass traps afterwards. The combination will be better than either approach on their own, but the issue to deal with first is the one that is causing the problem, and it's important to establish whether that is vibration or not. If it isn't, then the room is definitely the first port of call.
Hi David,I didn't realize you were familiar with the components in question. Given your insight to the specific 'tables, you're probably right.
Pete, although I agree completely that his room is an unknown, its not variable. I don't think its unreasonable to consider that if BOOM is a problem now, and assuming a reasonable sound from the old deck, that some sort ov vibe control is a good thing.
We may well be a chicken and egg situation, well I'm not sure how good that comparison really is, but my feeling would be toget some isolation in place and then hit the traps rather than the other way round, butit looks like we all think he should do both.
