I am looking into isolation products as well.
Sorry if I am highjacking this thread.....
I have a Blue Circle BC27 phono stage for audition now and if I raise the volume high enough, there is this very low frequency energy being reproduced by the speakers.
My Pro-Ject Tube Box MkII phono stage does not do this either with rumble filter on or off.
I suspect few things as being the cause of the problem:
1) The problem is feedback and not really a turntable rumble per say;
2)the table isolation;
3)BC27 stage reproduces these lower frequencies and Pro-Ject attenuates them.
I have my table simply on the top shelf of a Salamander Archetype 2 and there is nothing in between the shelf and the table. Table, a Pro-Ject Xperience, has stock cone feet.
Am I correct in my assesment of the problem?
How can this be cured?
If the isolation is the cause, would a Mapleshade platform with isoblocks be more or less effective than, say, Ginko Cloud 11?
Thanks!
