It seems that to use an UPS is not a good idea if we talk just about sound quality. But:

- What about the data (songs) you have in the hard drives?. Could they be lost in case of a blackout?

- What if I connect the UPS into the power wall and a passive isolation or transformers to the UPS on one side and to the computer on the other side?. Couldnīt the transformers clean the dirt of the UPS and computer while at the same time the computer would be protected from a power blackout?. 

On the other hand, some time ago Iīve tried several different power conditioners from Isotek, PS or Audience and my conclusion is that none of them provides something different than what Iīd call just a tone control, similar to what some sophisticated power cords do. At this time I donīt use any power conditioner and only would use one if I can protect the data and at the same time not harm the sound. Thatīs why Iīm interested in the UPS on-line.

Has anyone tried an UPS (Uninterruptible Power Supply) with the computer?. The UPS besides to protect the computer when the input power fails also filtrates the mains. I wonder if an UPS could affect in any way the sound of the system with the NOS1 in it.

I tried one of those true online double conversion UPS thing for computer and it was no good eventhough I picked one that is quite a bit bigger than what my music server needs. Dynamic was limited quite a bit. I did not try PurePower but I also tried PS Audio Powerpack 1500 (I think). It was better than the true online UPS but it still degraded the sound a bit. Now I just plug my computer right into my passive power conditioner which plugged into Isoclean isolated transformer.

Unfortunately I live on 11th floor of an apartment building. I wish I could try the separate ground rods for my stereo system. Somehow I don't think stikcing copper rod into my flower pot on the balcony will work unhappy

Hi

Music files should be treated the same way as other valuable data files. Power failure is not the only cause of data loss. HDD crash, virus infection ........ You name it.

You need to back up your valuable music files.

Thanks Praphan and Suteetat, Iīm going to forget about the UPS and probably Iīll use some kind of pasive filter as you said.

I am a XXHighEnd user with a bad experience of PurePower to contribute to those considering it.

I tried to purchase a PurePower 1050i in October 2010.  The European distributor had two available at a discount (I gathered later that they were flushing old stock) and I ordered one.  It took three weeks to do just that - the man was a terrible communicator.  The unit arrived, eventually, after a month.  On plugging it in, the display immediately went to FAULT!!!.  The unit passed a current to my equipment (at that point just a lamp as a precaution), but the display was clear, even when restarted.  I asked if there was anything I should do before returning it.  After one week of fruitless back and forth I stated that I wanted to return the unit as I no longer had confidence in the product or the company.  No reply for five days until I sent another email demanding a response with a read receipt.

At that point the US Sales Director got involved who immediately relayed to me the wonderful accolades that a recent customer in Scotland had sent.  He ended with:  PurePower is the real deal, worth a little bit of hassle for what it does.  I guess that is why he is head of sales!  He won, I wanted the unit after all, so I tried to work with a technical guy in Canada.  The result was Fault!!!

It took ten days before I got a response from the USA that he would get the European to arrange for a return.  It is now 16 weeks later.  The unit was returned only five weeks ago, and I heard nothing back from Europe or the US.  I sent an ultimatum last week that I would put the matter in the hands of an attorney if I did not receive a confirmation of payment by the end of today.  The Head of Sales read it, but never responded.  The European distributor responded with a promise to make the payment.  Today I notified them that they had missed the deadline and immediately received a response that the payment was sent and they could fax me the slip.  That was followed by an email saying that the payment failed, despite them having my international payment instructions since December.

A long story.  I am contributing this because I would have wanted to read it when I was looking into PurePower.

Sad story ...

What I would do (I realy would) is threaten them by stating their names right in this topic if nothing changes, put some nasty (but reality !) words like "hoax" next to it, and wait for Google to catch it (usually within the few hours for this forum). So, don't put that in any posts yet, because they (all instances) have to have one chance, and you shouldn't be sued for spreading the wrong word. Give them a link to this topic (your post above) if you want. Point out that sales really will drop because of your upcoming post.

Give them a quote like

"PurePower 1050i in October 2010"

to feed into Google, and proove to them that it will really work the very same with whatever names you are going to mention later, if needed.

I hope it works out for you !!

 OffTopic  I feel for you, PNCD.

I have yet to experience the same level of support like what Peter has provided in the stereophile/audiophile market without paying $$$ for their products first.
