QSA FUSES

+1 Fuse Box.

Had a QSA violet In my EAR 868 preamp, which was a nice upgrade. 

Fuse Box takes my system to another level.

Fuse Box is imo one of the best tweaks/ values available today. 

I agree the Fuse Box is awesome! It replaces the fuse and protects your equipment. I have 2 of them in my system.

I am a big QSA fan.  I would forget the LPS.  Put the best one you can afford in the Dac followed by the amp.  Another suggestion is to go with a QSA Jitter plug.  I had great results with a used crystal silver QSA Jitter plug that I used at the end of my Inakustic 3500 Power Conditioner 

I’ll eventually try QSA products based on Stereotimes and other rave reviews.
@willgolf thanks for posting about the QSA Jitter plug - using before the conditioner makes since, not sure if my balanced power EquiTech would benefit
