What can I improve in my turntable setup?

If you just moved into a new house then you have no clue of how anything should sound in the room you're in. The turntable might sound perfect, but the room won't let you hear it...

I'd try a set of high-quality headphones with the turntable to see how they sound. Then maybe I'd take some test tone measurements in your room to see if there are any major dips or peaks in the room response that may be influincing the type of sound you're hearing. Maybe try the speakers on a different wall to see if the acoustics improve.

It always takes me quite a while to experiment and make incremental improvements whenever I change rooms. Never, ever have I installed a system in a new room and had it sound fantastic on the first try (although I suppose that could happen in a fairy tale or once in a very great long time).

So it's not necessarily your lack of proper turntable setup. There are many other factors to consider. And you haven't provided only a scant few details for us to work with. How can we help you complete the puzzle with so many crucial pieces missing?

Have you had any success with any other sound source(s) (CD, for example?) sounding wonderful in this particular system?

Rotary 914, you need to tell us some more so that we can help you.

Are you happy with how your system sounds using another source - e.g. cd or tuner?

Have you experimented with speaker positions? Moving them a few feet further towards or away from your listening position can make a huge difference in sound. Also, I've found that having dissimilar materials on opposite surfaces helps i.e. a bare wall behind the speakers with a bookcase full of books on the opposite side of the room.

What happens to the sound when you clap your hands in differnt places in the room? If there's a pronounced echo then you would need to dampen it down with more soft, absorbent materials.

If your turntable sounded good in your previous room then it's unlikely that you will get that sound back in the new one just by tweaking the set up of the arm and cart.

Is the new room size significantly larger or smaller than before?

From what you have said, I don't think your problem is acoustic isolation but you could check by putting the cart on a record with the platter stationary, turn the amp up to a loud listening level and then gently tap the floor and the concrete block to hear what happens.

Hey just to add to the options list I suspended my vpi tnt off a dowel unto another dowel with rubber bands. And I am very pleased it seems to have helped but this is just the beginning I intend to do even more e.g. instead of wooden dowels maybe heavy steel rods 1 " in diameter to add mass. I may also play with springs rather than just rubber bands I may even try using both, since this is just the beginning of this project it may take a while before I can come to a conclusive and will post the end results if worthy of mentioning.
