This pretty much sums up my agnostic position in life as much as in audio. Is this blissful ignorance or am I just kidding myself?
@amg56, the BL-91 is a very nice table, but are you using it with the original feet? I discovered that this table can be elevated to a different level by replacing them with something more substantial. I’m using four Finite Elemente Cerabase footers now. This may be stretching it, as these retail for almost as much as I paid for the table. But I had these lying about doing nothing, so it was an easy choice. I’m sure there are alternatives that are more cost effective and still give you the option of levelling the table and - here comes that dreaded word again - MASS loading the table.
Speaking of which, this might also be an interesting option for your DDX-1500. I believe it has the same spring loaded feet as the RX-1500. I replaced these with the R-15 stainless steel feet for - oh dear, here it comes again - MASS loading the table. That proved to be a nice improvement!
