My Favorite Tweaks, What is yours?

By far the most notable tweak that made a huge difference and it cost nothing.

Getting a better understanding of the bass nulls/dead spots in my room led to far better bass. Simply learning how the sound was affected by the location of the subwoofers in relation to my seat.  The best result came when, out of frustration, I did the unthinkable and placed one sub directly in the corner and the other mid-wall sub both turned 90 degrees inches from the wall. "but you're not supposed to do that!"  It removed the null in the middle of the room and the bass was improved through out the entire space.  Tight and dynamic levels are easily controlled by gain control. The improvement was a major transformation.

My fav tweak has been system grounding. I use the Nordost QKore but there seems to be many different options out there now. Its hard to describe what it does, but once you hear a ground tweak its hard to go back. Does not work in every application or on every component tho.

Second fav tweak is isolation footer, specifically Stillpoints.

Effective tweak. Grounding is way underestimated...

But i designed my own box...(almost no cost save for the quartz and various minerals used)

Why ?

Price: QKore 1, $2499; QKore 3, $3499; Qkore 6, $4999;

I took out all  my hifi tuning fuses. I cleaned the ends, then before reinserting thin, threw them in the trash. It all sounds the same, but I feel much less gullible.

A few tweaks I have been doing for years. As many here might know, I damp horns, woofer frames, cabinets, equipment chassis, everything. Another tweak that for me was always significant with improved sq was to remove the power cord from a power amplifier (non IEC inlet) and install (hotwire) a heavier duty power cord/plug to the design. A couple that come to mind are Adcom, Soundcraftsmen, Hafler, Phase Linear, SAE, and so many more. It turns out, the puny power cords on these amps are a bottleneck to the capability of the amp, as some of you might imagine. I also attempt to decouple the power transformers from the chassis, which on some designs makes a significant improvement in sq. These products are always "out of warranty", and never had an issue. My best, MrD.
