Thanks Norm,
Five years ago after Thuchan listened to my system, he suggested I look into an isolation stand and I investigated Minus K (I didn't know about Herzan).
The trouble with the Minus K (as you would know) is that it requires the load to be more or less centralised and evenly spread.
It can't cope with isolated individual loadings. It's large-scale wobble movement was also rather alarming....😱
I'm sure it suits your turntable perfectly. Can you remind me what turntable you have mounted on it?
The degree of effectiveness in using an active or passive isolation platform largely depends on the amount of air-borne energy in the room.
That's a common assumption many make but I doubt its validity.
Just think about it.......with the Minus K stand, you have not decreased the amount of 'air-borne' energy one iota and as you turn the volume up.....you are certainly increasing it.
Yet isolation stands (of all types) cannot prevent the air-borne energy in the room from interacting with the turntable plinth, platter, tonearms and cartridges directly.
The fact is, the air-borne energy is not of a sufficiently low frequency (and amplitude) to be a direct consequence.
More likely that some of this air-borne energy is absorbed by the rooms structure (including supporting shelves and stands) and transferred via 'structure-borne' feedback.
That's why the Minus K and Herzan stands were designed to combat 'structure-borne' vibrations of the lowest magnitude.
The Herzan is certainly a 'plug & play' design as you say.....
I just hope the electronic actuators and motor controllers have a long and durable life....🙏🏽
