Vibration Issues / Turntable Decisions

Wall mount is an option, but ideal because I have molding that runs around the room at the ideal height so the TT would be quick high and look out of place.

Currently it is sitting on a Marble topped console, but the issue is the room is over a crawl space on wood floors, so shockwaves from walking are quite pronounced and travel well.

Here is my setup. As you can see the wall-self would look quite odd. I will try securing the cabinet to the back wall, good idea! The TD-150 does go nicely with the Decware equipment, I would like to keep it.

Out of curiosity, would there be any benefit to moving to an MC cart or is a 2M Black going to be a great spot to hover around? The MMF 9.3 came with the Eroica LX MC, which was appealing, but of course that also implies a $500-1200 Step-Up Transformer pushing the total upgrade cost a bit up there.

@roxy54  Thanks! They are Decware HR-1 radials, absolutely amazing! I'll try some bracing this weekend and report back on my status.

@audiopoint the rack is open to store my vinyl records in it, no bracing. :-\

@bdp24 lol, ultimately a new listening room needs to built in the house for anything super crazy, this is the first room when you walk in the house. Aesthetics are somewhat important ;-)

I'll take a look at some options. I was also toying with the ideal of bringing home a MMF 7.3 or ClearAudio Concept from my local dealer to see if a non-suspended table works more favorably.

Always good to do a T test.

Yep, 100% right on. Going to take some time this weekend and investigate some options under the crawl. I only have 2' of working space between the bottom of the floor joists and the earth below.

Stay tuned!

The slippage problem seems to be normal upon start-up of the TD150. I have decided to keep the table as it is an impressive setup. There are some good and relatively cheap options to brace the room.

@toddverrone - thanks ;-)

@geoffkait exactly, I want to spend time on improving isolation, the original reason for this post was because my previous non-suspended table had none of these issues. So I am trying to decide if going to a mass-loaded TT would be a better first step instead of investing tons of isolation.

Current project for this week is to get some 2x12s and some bottle jacks to see if that will stiffen up the floor and stop the shake.

@kavakat1 thanks, that is my plan for this weekend!

Checking in... wanted to circle back to the post with some findings.

1. Supporting joists under just the listening room was not helpful. The foyer/listening room/dining room all have this trampoline floor issue.

2. I borrowed a VPI from a local dealer and set it up in the same spot with supports in crawlspace removed, no skipping issues.

So while the Thorens TD-150 is a fantastic sounding table, I think after the move from a slab to crawlspace, its time to let it go find a better more-suitable home.

@slaw thank you for your insight and opinion, sorry for not disclosing the slab-crawlspace move up front.

Really appreciate the ideas here. While I am not sold on moving to a VPI, I think the combination of increased support in the room, dedicated isolation platform, and a non-suspended TT is my direction.

Have a fantastic evening all!

Ciao,
Ron

@stringreen got lost in the thread my friend, let me go give that a shot right now.

@stringreen thanks for the suggestion, locking the back cabinet to the wall didn't fix the issue because the issue wasn't with the TT per se. The cabinet combination with the TT is the real issue.

Aesthetics is important in this room for the WAF. It is the first room as you enter the home. Once I finish the attic and move the listening room up there I will be able to place everything where it will fit best. I will also be using the golden ratio when building the walls to ensure the best possible starting point.

That said, I am going to keep the cabinet in the room because its where all my wax is and since the room is so small, having any additional furniture in the room is not going to be feasible. Already a little claustrophobic in there.

I have decided to sell the Thorens and look for another replacement, it is listed on A'gon now hopefully at a price for a quick sale.

Thanks again to everyone who has made some great suggestions here. I am not super handy, so a lot of the construction related projects might have been do-able but not ideal for me.

Happy listening all!

Best,
Ron
