All of audio is trial and error. Test and evaluate, tweak and evaluate some more. This is no different. Anyone things a system is plug and play, sorry. This one thing more than anything else will hold you back.
On 2nd thought, in this context I presume this trial and error only applies to the Nobsound since they can be run in many configurations, unlike isolation products from other manufacturers. With the Isoacoustics Orea, one can only switch between 3 and 4 footers under a component, that’s about it I guess. In other words, the Oreas can be considered as plonk and play. The Oreas either work or they don’t. If the Oreas don’t work, one cannot do any changes to make them work. With the Nobsounds, if they don’t work, one can change the spring configuration to make them work.
The setting up with Nobsound is also a lot more finicky since adjustments are required with unequal weight distribution of the component. If the springs of the Nobsounds are not adjusted, the component will sit lopsided. With the Oreas (or other isolators), leveling isn’t an issue as the height of each footer is fixed, unlike the Oreas where the height will vary with weight.
I presume the Townshend Seismic Pods are also rather straightforward in their set up without much effort required, perhaps with leveling adjustments they are pretty much plug and play? Assumption on my part.
