What most of you are saying about orienting the cone tips so they point away from the source makes logical sense to drain the energy...but for whatever reason in my setup they sound better pointing up. However my arrangement is a little different. My turntable sits on a BDR The Source platform with BDR cones (pointing up) between my rack and The Source platform. I have flipped them numerous times and it isn't even close - I lose much dynamic range with tips down on the rack under The Source platform - in fact it sounds downright "thin" as if all the musical goodness got drained away along with the "energy".
Ceramic insulator cone under phono stage shocker!
I have used small ceramic insulator cones underneath my phono stage for quite some time.
Previous phono was a Gold note ph10 and it did not make ANY audible difference I could detect which way up the cones were so I had left them cone upwards.
When I changed my phono to a Manley Chinook I just left the cones same way.
This afternoon I decided to flip them over so cone down just to see.
I honestly could not and cannot believe the difference!
I may have lost a smidge of low bass but everywhere else is improved in spades.
Much more detail, resolution, air, imaging, dynamics.
Just completely shocking how much better a small change has made.
But I am perplexed why such a huge change on the Chinook where I noted nothing on the ph10?
Any theories here?

@slaw I’ve actually considered the exact same thing and I suspect you’re right. My rack sits quite close to one of the speakers and the cones are probably dissipating some energy transferred from the floor or even sound reflections from a nearby corner. I have a Symposium rack with spikes that sit on four Precision couplers (maybe I should be using dampening pads and not couplers?) and I use Gaia III feet under my speakers but together they may not be enough to keep the seismic out of the rack. Cones pointing up may be the perfect workaround for me as it would be very difficult moving the rack considerably farther from the speaker. I have a couple of GIK tri-traps on order, one of which will go in the corner 4-5 feet behind the rack - this may helps as well. I have a 24x48 absorber wall panel behind the rack but the corner is untreated. Thanks for weighing in. |
@slaw Agreed. I’m going to look into something that acts as a decoupler that the rack feet can sit on. I'm open to any suggestions from folks. I'm using the foot configuration at the bottom of this link page. http://symposiumusa.com/pcouplers.html |
