Here are my thoughts on the subject:
I've used a PS Audio Dectet for years. It's plugged into a PS Audio outlet, which has very good grip. I like the way the Dectet protects from power line anomalies like low or high voltages. The Dectet also must provide some kind of line noise filtering because the sound staging improved and more detail was evident. I also have a whole house surge suppressor installed on my electrical panel box.
I bought Furman Elite 20 PFI and installed whole house surge protector. Furman has strong non-sacrificial under/over voltage protection. It doesn’t lower dynamics since it contains huge inductor and capacitor storing energy for peak demands. It has 3 banks of 4 outlets each for amplifiers (high current), audio-video and video - all filtered. I bought it used for $650. I also installed myself whole house protection by replacing double 20A breaker (Siemens style) in the panel with overvoltage protecting breaker:
(6th in order - your style might be different). You could install stronger protection mounted to the panel but for that you should hire electrician.
@erik_squires, thanks for link to the article. It is very informative and gives me a clearer picture of which direction to move.
Also, thanks to everyone else for their suggestions.
I have to do a little more research and see what I will do and what might be best for my system.
I don't want to get too carried away as I know that is easy to do.
Just gave away my Furman Elite 15i or something like that. It performed well, cleaned up the power and nothing ever bombed my components.
Replaced it with the Decware ZLC which eviscerated the Furman. In every aspect of dynamics, noise floor, attack and space between instruments and voice it improved the experience. Loaned it out to a friend and he experienced the same thing in his power noisy apartment.
No surge protection (Steve Deckert does not seem to think that is an issue), excellent spike protection and conditioning. This thing is a beast. 6 outputs. 3 month waiting period. Placed on a Quadraspire Sunoko Vent stand with VPI DB5 Magic Brick on top.
System: Naim UnitiServe server with custom PS, Mojo Audio Mystique V3 DAC, Manley 300B pre, ATC 40 active floor standers with Gaia footers. Decware ICs, Patrick Cullen PCs, Nordost Valhalla digital cable, Quadraspire Reference X stand.
@celtic66 , that's an impressive system you have there and for you to say how you feel about the ZLC mirrors what I've heard about the EquiCore, which seems to do the same thing with the ZLC coming in at a better price. A 3 month waiting period speaks volumes and piques my interest.
Thanks for mentioning it as I read about it some months ago but forgot about it.
All the best,
jay73 That's a great question and the answer is yes. Because, it will in all likelihood not remain an entry level system. The benefits will only progress as the system improves. Besides, don't you want at least spike protection in case something nasty blasts through the electrical wiring? Decware also has a very good return policy.
The Magic Brick DB5 is an old product from the 80s that is some sort of 8 lbs. of material wrapped in a wooden case designed to be placed on electronics.
It's an enigma as some have tried to copy it after cutting one open and never, to my knowledge, reproduced the results which also vary by system. Some experience less transformer hum when placed on top, others a lower system noise floor, some exclaim improvement in dynamics and yet others shrug and say no difference. I get quieter system results.
I've placed them all over my system, just on the casework. I've also an HRS plate on the casework of the Naim UnitiServe. It all works to my ears and that is all that matters.
