Townshend Springs under Speakers

Ah, good point @mitch2 !

I live in an older, urban apartment building from the 1930s.  Top floor of a 3-story building with wood floors that are a bit creaky and not well insulated.  I can hear my downstairs neighbor sneeze.  

In that case Podiums first, for sure.

Thanks, MC! I’ll probably start then with the pods under the components. I’ve only had intermittent luck with my DIY rollerblocks, and I’m thinking that success with these devices is hostage to the weight/pull exerted by heavy power cords. Trying to neutralize cable pull with Furutech Booster clamps seemed to defeat the value of the rollerblocks and I began to suspect that it was best to use a very light touch with the Furutech clamps when paired with ball-bearing isolation. I take it that this might be less of an issue when using 4 Townshend Pods (as opposed to 3 rolllerblocks) but was also wondering if the "clamp" strategy of the Furutech Boosters was itself a dubious solution to cable vibration that needed to be addressed as well.

Just read your update:  podiums!

Podiums under speakers
pods under amplifier (s)
pods under pre amp
pods under Dac/streamer. 
That’s the order of improvement in my system 

The greatest improvement for me was Podiums under the speakers.  I then placed the pods under my tube pre amp replacing the HRS footers.  Speakers first in my opinion.
