I have owned the Seismic platforms for a couple years and they are transforming .
Prior to the Podiums I was using spikes with Combak Harmonic footer.
It is one of the few audio products that is universally praised by people who actually own them. Yes they are expensive but chances are they make up less than 10-15 percent of total system cost. They’re improvement is actually a great value. The beauty is every single piece of your equipment benefits and changes in cables,fuses,power supplies, are much easier hear.
My biggest takeaway from them are the space around the instruments and not only the depth of the stage but the actual placement of the players. Live recordings are especially impressive as you will hear the audience in front and the singer a few feet back and guitar player a couple more feet back and to the left and the drummer 12 ft behind the singer but 8 ft behind the guitar player etc. I guess you would call it layering .
All the other goodies apply, texture in vocals, improved bass control, etc.
I do have a golden ratio room which helps, it is a converted garage with a cement floor. 2x12 floor joist filled with foam built on top of the existing cement slab. I knew where my system was going to be so much more than typical cross bracing etc.
Finished flooring is LVP with cork backing . It floats so probably not the best but it looks great and easy to take care and self installed Could be another reason I felt I had such an improvement with the Podiums
The Townshend folks are awesome to work with and will work hard to make sure you can afford your Podiums . I went thru all Herbies, Stillpoints,Combak Harmonic ,chain . Save up your money and buy the Townshend Podiums .You won’t have to worry about selling them for 50 cents on a dollar in a couple of years!!
