Where to use Isolation devices

Alleung - How did they do the comparison of the Sort Kones at the show? I've always wanted to hear two identical sources sitting side by side with one having Sort Kones for an immediate A/B change. Taking out the kones are swapping their location should give some confirmation of the actual change. Since I only have one SACD player it takes a few minutes to swap the Kones in and out and I'm convinced that the placebo levels increase in anticipation of whatever the expected result is. It's almost impossible for the average joe to own duplicate equipment...

Using Nordost sort kones -- in placement priority FIRST: the AC power conditioner/distributer (like a Shunyata Hydra, etc.), then your phono stage preamp, then source equipment (SACD player, DAC, server, etc.) then your amp/preamp/integrated, etc. I received this priority list from NORDOST at T.H.E. Show at Newport Beach 2015. I bought 12 bronze kones at the show and WOW, what a huge difference. Highly recommended.

I use Nordost cones as well and yes they are very good.
But they actually made the sound worse when placed on
MDF shelves , on 4" maple they are outstanding .
IMO the Bronze are so much better than the entry level AC I would not consider them.
