Tweaks - An Honest Discussion

I know there is a lot of talk about performance tweaks in this forum and the value that can be realized.  I've started this thread because it seems that folks tend towards believing they are either the silver bullet to sonic bliss or conversely simply snake oil.  I believe tweaks are somewhere in between and in most cases, worth about what you pay for (crazy  I know).

I'm open minded to tweaks and have employed many in my system over the years including isolation, fuses, footers, HFTs, cabling, cable risers and attempts at reducing RFI (among others).  While I believe that many of these tweaks incrementally helped me get better performance out of my system I never for a second found any tweak make a transformational difference the way that a significantly upgraded piece of gear brings to the table.  I think many of us have been quite happy with our systems over the years but that doesn't mean implementing a tweak can possibly compete with the benefit of replacing a piece of gear that is well matched to elevate your system. Just because you're happy with your setup doesn't mean a major gear change can't really elevate the experience - surely well beyond any form of tweakery.  

As an example, I've been very happy with a Hana ML cart and how it's performed in my system.  I recently decided to acquire a Lyra Kleos cart - for a $2K increase the change has been transformational in terms of dynamic range and ability to convey detail and imaging.  There has never been a dot I've placed on a wall, carbon platform placed under gear, or RFI shielding device I've ever used that could possibly come close to this equipment upgrade.  Same goes for upgrades to my system over the years in terms of amps, pre's, and speakers.  For anyone to suggest that through tweaks alone you can elevate your system to a level that only gear changes can achieve simply falls flat in my experience.  Some may be shocked to hear that most of the time a $200 tweak truly only gets you about $200 worth of improvement (if any) and not the equivalent of a $5000 gear upgrade. I know there is a certain allure that by simply being smart and applying elbow grease that we can extend the sonic limits of our system well beyond it's design, parts, and capabilities but that's just not true IMO.

What's your experience been?
