Have anyone compared double conversion sine wave ups from APC, Eaton, Liebert etc...against good power regenerators like PS audio ? Please note that I am NOT referring to sine wave home inverters here.
What power conditioners do you use?

I use a Eaton 1kva ups for my stereo set-up. Connected to a barracuda distribution box, which has all my gear. Luxman amp, Rega TT, Cambridge cxn and marantz CDP.
Hi Sandyj
The ps audio p1200 is in a completely different league compared to power filters and conditioners. It converts in coming AC to DC. And regenerates it back to AC. So the incoming AC wave form is completely destroyed along with the other gremlins. And one can choose even preferred output frequency from anywhere between 50 to 60hz. So as You can see, it is a pure sine wave AC regenerator that can continuously pump out 1200 watts of pristine power, as it is basically a 1200W class A amp that is forced cooled by fans. It is claimed to be even better than than the newer PS audio P10 power plants as they have utilized a different tech to reduce the size and the heat. And the PS1200 weighs a mammoth 76 kgs to deliver that kind of output. So it is probably not fair to compare power filters and conditioners to what it does. As it's in a different league all together.
The above said, usually when anyone gets a power conditioner, they always plug the entire system into it. The whole audio chain that is. And there will be a definite improvement, that is Because of the purer power going to the streamer, dac and preamp. But not because the big power amps gain anything from it. The overall improvement is Because of improvement in the source components, and not the power components.
And on the contrary if the conditioner can't match the power demand of the amps, there will be a loss of dynamics. So id advocate amps direct to wall, and only source components to filters and conditioners

There are many who like the passive way though. Purists never like even one component being added up in the chain. It should be like the improvement should be there but it should be as good as a straight connection.

Can you post the exact model number or link ? I have an APC 2kva double conversion model..almost 6 years now. Time for a change.

The UPS is making a buzzing or humming sound. I've asked the dealer to check it out. I'll send the model number tomorrow when I get back home. Thanks
I am using batteries on my preamp - Exide 12v+12v, 7 aH, same for my subwoofer to reduce challenges posed by AC supply. My Blueray player has quite good SMPS supply. For my 300B monoblocks have built a line frequency harmonics suppression device which is currently under test. Hope this answers part of your query.
Then that probably doesn't apply to me....I have probably 13 boxes in the chain and takes me 5 mins to power up everything to get the music playing these days. Anyways I don't consider myself a audiophile and neither a purist of any sorts. So I guess Iam free to play around, without being shackled to any old audiophile premonitions
Wow I didn't even know AC power posed challenges
Subwoofer runs on car battery ?? Sorry about my ignorance .I just saw this thread on Audiogon and it reminded me of your post.
Sell your $$$ cables and conditioners... affordable LITHIUM is here!
I wanted to give you a frame of reference as to where I'm coming from and most importantly a first impression after 24hrs! I've been an addict since...
1000+W Lithium batteries are available to run an entire audio system. No power conditioners, no CVTs, no surge protectors, no power cords. Sounds like heaven to me. To add icing to cake, it's sold at non-audiophile prices.
There seems to be audiophile version of this: Stromstank or something at $30,000.

The owner seems to be gushing all over it... With my Lyngdorf 2170, I guess the Yeti 400 would be enough to power my amp and laptop... Research begins now...
Turns out, some Amazon reviews dated 2016 are not happy with the battery shelf life..

Shipping and customs is not an issue as the manufacturer will give the required documents for customs.. We might have to pay a bit more but not that big an issue.. My concern would be
1) how long do the batteries last
2) How easily can they be sourced if locally or imported if something goes wrong..
3) Is there any benefit in sound quality over Lead Acid car catteries
4) How is it any different from a Pure Sine Wave UPS?

I'm not a technical person, do please forgive this question: Doesn't the voltage drop as the battery gets discharged? And isn't that a bad thing?
I charge my preamp batteries once in 15 days ( average usage 3 hrs per day). Subwoofer battery needs charging twice a week. Charge time around 2 to 3 hrs for full charge
