Machina Dynamic Brilliant Pebbles?

Tgb - just wanted to mention, esp. as you apparently have not found the pebbles to be particularly effective in your setup, that all cooton and rubber seals should be removed from the bottles prior to placing them in the room/system; These materials are strictly for shipping.

In addition, as I don't recollect actually selling the Bottles (directly) to you (I could be mistaken on that point and please correct me if I'm wrong), you may not have the complete instructions/suggestions for use that I provide to customers. If this is the case, you might be interested to know that an especially effective location for one of the large or medium size bottles is on top of the Transport or Player directly over the spindle of the transport.

Cheers - GK

Tbg - Hi, the Large size are intended primarily for room corners and on top of tube traps and output transformers of tube amps.

The next smaller size (what I call the "Mini") is intended for top of transport/player, top of turntable armboard, top of DAC, and other somewhat unpredictable locations.

Some customers have had very (I mean very) good results w/ the Large size on top of transport/player, even tho Mini is recommended.

All sizes of bottles seem to be pretty room and system dependent in terms of degree of effectiveness. At CES last year we had "Mini" on SACD player and Large bottles in all four corners.

If you recently removed the rubber seals you might have noticed how much more open the sound became w/o the rubber seals. Also, it is unpredictable which two corners respond best to the bottles, sometimes the two behind speakers, in other rooms the two behind the listener. In many cases results in corners are big. Big big.
