Cheap tweaks...What would YOU reccomend?

Many of you know about the less than stellar quality music a USB port provides. But in many cases this is due to the fact that on a great many DAC's, the USB circuitry is actually powered by the computers USB port.

DAC's such as the Bifrost, Gungnir, and the Ayre DAC all use the USB supplied power for their USB interface.

There are options out there to clean the power up, such as the Schiit USB Decrappifier ($100). But you will need a second USB cable for that solution.

However, the Power supply and USB cable separate audio signal cable, splits the data and power conductors so you can bypass the USB power with something a little more stable.

It's nicely built and improves performance even if you plug both data and power USB plugs into the computer.

I tried a few power adapters that I have and compared them against a battery power supply and found the Enercell and ASUS USB power adapters to perform just as good as the Battery.

Some other no name adapters I have were not as focused.

Improvements included a very focused image and much more clarity.

At around $78 total I think it's a tweak that many DAC's could benefit from

Back to the tunes :-)

1. Cardas or AQ caps for unused XLR and RCA I/O connectors on all your components. Don't realize noise exist until it's GONE.

2. Synergistic Research RED Quantum Fuse. It replaced HiFi-Tuning Supreme fuses and the improvements are excellent.

3. Synergistic Research HFTs

4. Remove/replace all SPS with LPS from your system. SPS pollutes your system with noise.

Smoking pot is cheap tweak $20 per week!

As long as you can live with mental and immune system decline .

Knghifi,
Pardon my ignorance, but what are LPS and SPS ?
