Just to clarify please, Geoff, are you saying that you prefer GS cones to MD springs in some areas or you have moved on from the cones?
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?

For those unfamiliar with Barry Diaments findings on seismic isolation control, this is would be worth reading http://www.barrydiamentaudio.com/vibration.htm |
Thanks Geoff for the explanation. I haven’t had any experience of using cones of any sort (maybe I should?) but I am getting extremely good results from using Ingress Engineering cup and roller balls directly under the components, sitting on a platform of 30mm thick slate with air springs for vertical isolation under the slate. I intend trying metal springs under the slate to compare. With the Bakoon 13R amp because it uses projecting heat sinks as footers, I use another layer of slate, so the Bakoon sits on this, with Ingress Engineering cup and rollers supporting the slate platform and they in turn sit on a similar platform of slate which sits on air springs. Ingress Engineering also make a version for isolating loudspeakers which I haven’t tried yet. If using these I would suggest using them with a platform of slate with springs under. With the Cube Nenuphar speakers I went for a simpler arrangement with them sitting on Townshend Podiums, which comprise a heavy aluminium platform with adjustable springs on each corner. There are a range of Podiums varying in size and weight capacity. I found a marked improvement in SQ using the Podiums even though the Nenuphar’s are already remarkable. |
