Isolation recommendations for my Pathos Inpol2 MkII, heavy Class A integrated amp (38kg)


Hi everyone,

I’m looking for advice on a suitable isolation solution for my integrated amplifier.

Amplifier:

Pathos Inpol2 MkII

  • Weight: ~38 kg\84lbs
  • Class A operation
  • Hybrid design (tube input stage + solid-state output)

Current situation:

The amp is placed on a solid rack, but I’m exploring dedicated isolation to:

  • reduce structure-borne vibration
  • improve bass definition and control
  • lower noise floor / improve clarity
  • preserve dynamics and timing (no overdamping)

What I’m trying to avoid:

  • over-damping (loss of bass attack and dynamics)
  • “softening” or slowing the presentation
  • unstable or overly compliant supports that affect imaging

What I’m considering:

  • dedicated isolation feet or pods (spring or hybrid designs)
  • possibly platform-based solutions if better suited for heavy Class A gear

I’m open to both high-end and more cost-effective solutions, but I want something that is properly engineered for heavy components and does not compromise transient speed.

I considered a solution by EPV but at 1200$ for a set, I decided I still need an extra  kidney.
Would appreciate recommendations based on actual experience with heavy amplifiers of this type.


Thanks in advance.

Nobsound springs

A set of 4 is good for 36kg which is at the very upper limit. I use them on everything including 3 pods under a 25kg turntable. Worth a shot at the $25 for 4 price. Maybe try 2 sets.

Failing that, I’ve heard good things about Townshend pods and platforms.

Set of 4 Green Seismic pods (up to 42kg) is $612.

Stack Audio just came out with a new isolation platform, worth a look.

Their products have received good reviews. I use there Smoothlan Regenerator with positive results.
