i live next to the long island railroad any suggestions on how to completely isolate my equipment?
Without moving??

Do you have analog, or are you all-digital?

Move to the Mts.
BOTH and moving in this world right now not possible LOL
A story. Years ago Lyric Hi Fi, the ultra hi end salon in Manhattan, Lexington Avenue to be exact, wanted to isolate its listening rooms from the Lexington Avenue subway which was at its door step. I had visited the place before they did a complete isolation project, and yes you could hear and feel the train, both in the basement and in the ground floor space. They did a major isolation project to get rid of the sound. I think they spent almost $1 million, in the early eighties, in doing the project. I visited after the project was completed. Most of the train noise was gone but you could still feel the vibrations. The moral of the story: move, unless you have $2 million plus.

Also, the Weiel concert space in Carnegie Hall had and still has the problem with train noise from the Seventh Avenue Subway, according to critics that go there often. This was after then spent multi millions in design of the space to isolate noise of the train. If the best engineers in the world can't make it happen, I think there is a lesson there.
I cannot imagine a good LOW rack with sturdy spiking into the floor will not work. Use 2 racks if u have lots of gear. Don't go too tall-laws of physics against you then.
I used to live in Bayshore, not too far from the track. No problem. As a kid I lived "ON" the Q26 bus route (b4 I knew about good isoaltion racks). Records skipped every time bus came by, but house shook too!
Well, if you can't move (why is it New Yorkers "can't" move? I never understand that, from someone that's changed cities and states 6-times), how bad is it when you're playing LPs? What do you have now?

I assume that you're not willing to spend $1 million for something that won't work, so how much are you willing to spend for a partial solution?

It would be helpful to know what you have tried up to this point, if anything. You might do what I have done, which is to use a wall-mount platform, a Brightstar Audio BigRock under the table, and spring suspension under the Brightstar. Not too expensive, very effective. I don't live next to the Long Island Railroad, but it might, and should, help to some extent. Can be used under all your source components.
Try also Mapleshade Nanomounts, drains unwanted vibrations away from the cartridge into the headshell, through the arm, and into the plinth. The plinth has to be firmly engaged on the BigRock, via some kind of spikes or other, to make sure to complete the eliminatiion of vibration. Worth a try, what do you have to lose?
The springs can be had through McMaster-Carr. You can see how it's implemented by visiting my system.
Best of luck,

I just changed racks something much lower and i just put my tt on doubled stacked vibrapods.

it really wasn't and still isn't a major issue i just want some type of peace of mind.

my next step is to get one of those wall shelves along with the vibrapods and call it a day.

any opinions??
well wait on the 2 plus years here in the house, i can count on my fingers and toes how many times i heard the record be affected by the train. and i have to say i listen to music at least 2 hours every day during the week and all weekend long.

this answers your question on how bad is it

thank you
