Cheap tweaks...What would YOU reccomend?

I'm not going to read this whole 2 year old thread but can offer the best tweak I've ever had. Bought a used copy of the original 'Rolling Stone Record Guide' (1979) off of Ebay recently. I had this book when it was new but misplaced it over the years. The guide and a good source for vinyl are the absolute best tweak ever.

I recently put my floor standers w/spikes on concrete pavers ($1.99 ea.) in my system made a difference of a two level upgrade.

hockey pucks! get a marble slab a little wider then your speakers, mount that on 4 pucks, and then put spiked or non spiked speaker on top. Also put them under the electronics feet. They really control resonance. paint one or two of them silver or gold enamel and place them on top of equipment and tell people there chakra stones!

What in the world is a two level upgrade? Is this an order of magnitude thing? From $200 speakers to $2000 to $20000 ? What are these levels?

I'm curious as to whether anyone else has tried this. I recently opened up my BAT vk-d5 cdp and placed a Mapleshade small heavy hat directly on top of the transport. There's enough clearance for the small hat to sit there to allow you to put the cover back on. I noticed a much punchier bass, better clarity, focus, and an overall tightness that only comes with much more expensive tweaks. If your cdp allows for this, try it. Just be careful moving the cdp around so the heavy hat doesn't slide off and break the tubes or other parts.
