My hifi room is uncorrected by any digital nannies (I use a Loki EQ for my headphones only) and my system sounds astoundingly good in its room with a what I suppose is called a "room sound." Music generally takes place in rooms if it's played by actual non digital instruments (as opposed to a synth played through headphones), and that sounds like real life in my earballs. I have some vibration pods here (they keep things from slipping around) and there but I really don't think vibration is such an enemy (my powered subs have the amps in the box with the speakers...horrifying!). If you live in a metal water tower or a shipping container with no furniture, you could have room issues...otherwise, room treatment obsession seems unnecessary...get some furniture maybe...a rug...sheep...
Do YOU have a flat frequency response in your room?
The most basic truth of audio for the last 30 years is listeners prefer a flat frequency response. You achieve that through getting the right speakers, in the right position, in the right room, and then use room treatments and DSP to dial it in. If you are posting questions about what gear to buy and have NOT measured your room and dialed it in to achieve a flat frequency response FIRST you are blowing cash not investing cash IMO. Have you measured the frequency response in your room yet and posted it?
