With all respect, maybe the heading can be “tweaked” to say “sensible purchase”, versus “sensible investment” - as I have yet to see anything in this hobby as an investment.
Today, a respected audiophile listened to my system and indicated there was gain to be had in the mid range.
Flashing back, I installed Stillpoints Ultra 5’s under Wilson Alexias a few weeks back and noticed the same thing, however, I can never add only one thing at a time and believed it may of been related to updating an XLR cable.
I asked for help to remove the Stillpoints and put the OEM spikes on, and 20 minutes later the mid range literally snapped back.
So was this a waste of money, it could be seen that way. In the spirit of things, I’m moving a few things around and see where anything can be repurposed for the better, I have had my share of tweaks and now taking a break from any new acquisitions, just how long is the question .
