Add checking whether your speakers have been moved accidentally so that they aren’t in quite the right place any more.
Also add borrowing a mate’s record cleaner and putting though it anything that hasn’t been cleaned for a decade or two.
I would put sticking a chunk of wood or stone or whatever under a Naim box in pretty much the same category - nothing lost by trying it except a little time.
“Part of the design of stands and equipment is how the vibrations go to ground,”
That’s a lightbulb statement. I’d always assumed that the purpose of stands was to separate vibrational interference getting to the equipment VIA THE FLOOR, not dispersing from what was in the boxes from (presumably) speaker-to-box air transfer.
And also the mechanical noise from things like humming transformers or CD mechanisms. This is why taking all your boxes out of the room a putting them in another room won’t necessarily improve the sound. A good, well designed rack or support is the only way you are going to sink that energy to ground.
Despite the astonishing improvement to the SQ by getting rid of all the silly extra feet and sitting the boxes directly on the Isoblue shelving there is just one downside.
Steady now … just trying to help. That PS was designed for the entry level streamer - IIRC when the DAC was built that PS model didn’t exist … the burndy plug on the DAC envisaged XPS or 555PS. So it’s a valid question - maybe Heroes could be playable after all?
I have an old friend who qualified as a gyrocopter pilot and took me on a trip from Kent to Essex across the Thames estuary on a beautiful sunny day. An unforgettable experience as the cockpit is of course fully open. Highly recommended
Hi Mike some time ago there was a long thread about “Support for glass” in the forum. Xanthe has developed an approach using silicon nitride ball bearings and 10 mm tempered glass (Link here). It is easy to build yourself and does not cost much investment. I have had very good experiences with it (as have other users) (Link here). However, I don’t have a rack, but a sideboard with very limited damping properties. I can’t judge whether it will do any good on the Isoblue rack.
Test #2. With the blanking plug in, the SQ is less detailed and sounds kind of “constricted”.
With the XP5XS, the opposite obtains. Open, flowing and more revealing.
So it seems that even if it was specifically designed to improve my old ND5XS, just the act of taking the nDAC power supply outboard is still beneficial.
