What makes the biggest difference in sound quality?

Fuses of course, start off with a good set and plan your entire system around them. Everything else in your setup is a virtual afterthought………..;)

The purple is an amazing fuse. It’s on par with my DIY fuse as far as clarity/distortion goes, but it has a more vivid timbre in comparison.

The DIY fuse has a richer presentation of the mids, the Purple is bit more balanced across the spectrum. Pianos especially stand out in every quality recording.

Overall a very nice fuse, and is definitely going to be a great upgrade on most HiFi systems 👍

1. Quality of Recording
2. Overall placement, rack & cable management.

Assuming that folks are happy with their gear, they experiment with cables. Most often the result is a mishmash of kit cross talking affecting each other.

Ted's products are innovative, and almost always improve the sound. (tried with my Devialet/Boenicke combo), but are very awkward to manage.

As most of the competition, they are contributing to the mess. Improving on ergonomics is the next step.

Starting with the power side is were I found a lot of gain in quality to my system. Good outlet and power conditioner. Plus the power cords. 

The most difficult to find component that is affordable is the power amplifier IMHO!

Rest in Peace John Bedini... and Gary...!
