Harmonic Resolution Systems (HRS) Platforms

Folks,

I am having trouble justifying another $7,000 for the lowest priced HRS frame, to accommodate my expensive M3x Harmonic Resolution Systems platforms.......around $2,500 each. 

While I understand that the frame and the platforms work as a "system," I currently place the M3x platforms and nimbus couplers, on a low-cost salamander rack......with decent results.

Has anyone had good results using HRS platforms on a high quality solid wood rack......walnut for example?

This would save me about $4,000 if it works.

Thanks in advance for the advice.
