Add-Powr Power Conditioner Review

@ozzy 

I have been using carver/Sunfire amps for years but they have all been solid state. How do you like the Carver tube amp?

@donavabdear 

Another device that can impart a "tube like" quality without using tubes.

It was obviously clear from the start the X4 allowed for more pleasing quality and tone. The session’s horns just didn’t seem to grate at my eardrums in the same way, they were all more polished, rounded, and the sound was less harsh. I already use valves in my Luxman LX-380 integrated, but the effect of adding the X4 was comparable from going solid state to tubes.- Buzz Hughes, HiFi+

If you wear headphones when you watch this you can hear the difference when the A/B compare, even through a low res youtube video:

+1, I have one Add Powr component (not the Sorcer ) in the front of my media room where my front end components are and one in the back of the room where my PJ and surround speakers are.

You should call and discuss with him, great guy and I have been using his stuff for years (decades)? Always a 30 day audition so no risk. Start with an entry level item for proof before you move up. I have never seen a professional review that panned or was lukewarm.

This is a recent review of a different product for your ethernet/USB connection. Often on sale for less than the MSRP:

Too funny 😁

I like PS Audio but believe this is different.
I would encourage anyone who is curious to call Bill for specifics about applications to your system. He also takes all of the risk by offering a 30 day moneyback.

This is NOT a power strip, when you plug it in it will impact all of the gear on that circuit, not just that individual receptacle.

Here is another thread from @bradmorris1 0n a different Add-Powr product, The Wizard:

BTW, Nordost bought out Bill’s prior company QRT (which I was a customer of prior to acquisition and still use) and still sells that brand today. The brands are different but Bill can explain the details of his improvements better than I can. I can say that the Add-Powr line is less expensive:

Well, nothing in that review helps understand very much how the system works

See the website and call Bill to discuss.

I think you’ll hate it though, after you took 30 years and spent $$$$ ($150K?) to find out it could have taken less time and been MUCH less expensive if you had bought a unit first.

😥😥😥😥😥😥😥

The good news is if you get a unit now you might not need to spend another $100K to finally get decent SQ.

🤣😂😁🤣🤣😂🤣

And they will improve the audio signal energy (signal-to-noise ratio) by as much as 10 - 15% throughout the audio spectrum.

+1, I find it was very impactful on my network too, my router, modem, NAS, etc are all benefitting. I plugged the most recent add power unit I purchased into the power strip that my PJ and back surround amps are plugged into in the back of the room. The picture from my PJ popped as expected but the nice surprise was the my entire system got a benefit, side surrounds, height channels, etc. The units synergize, even when plugged into different receptacles.

@cohsystms , any advice for @donavabdear who is being plagued by hum on his subs?

@erik_squires , if you got questions about power, @cohsystms is the member to ask :).

@cohsystms 

Great to see you and thanks for joining this thread! I am using an immersive audio system (9.2.7) and the soundstage improvement when I added my most recent Add Powr component was very noticeable. I might get an enhanced benefit because I am using around 12 active speakers with two internal monoblock amps each, one driving the woofer, and one driving the tweeter.

You know how a screen looks with a projected image on it when you go from living room (good) light to pitch black (crystal clear)? That is an analogy of what happened to the sound when I plugged in my most recent add powr upgrade. The sound went from being good (like a screen in the living room light) to crystal (like a nice Dolby Vision image in a pitch black room.) I wasn’t expecting that level of improvement and it made me smile, thank you! I will be looking forward to adding the Symphony I/O soon.

@ozzy

+1, some designers attempt this using a hybrid solid state/tube design but its expensive and not as good.

Are the tubes high maintenance? How many hours before they degrade?

@erik_squires 

At best it sounds like.....

You have 0 idea on how to answer that until you plug it in yourself. I don't recommend it for you, I think you will blow a gasket on how much other stuff you bought that didn't deliver the goods. It surprises me that for a member with high standards like yourself you just kind of dismiss it when it is in its own category, one you have 0 knowledge about or experience with.

@donavabdear 

If you want a tube amp, with a lot of power and low maintenance then check out the Carver amp that @ozzy is using.

I saw a blog post from tweek geek who reported good results with fuse rolling:
