[quote user="Paul S"]No, the ceiling fan switch is not supposed to read through the PP 2000. But, that's Showbiz, or so I'm told.No doubt APS has loads to say about it, as ever...Paul S[/quote]Actually the ground issue is not too much of a prob...

[quote user="TonyB"]I did not study PurePower in detail. They have 36V DC batteries. Do they use step up transformer after Class D amplifier or do they create high voltage DC supplies and then run the Class D ampli...

Last couple days, while the APS people are cooking a new version of their regenerator, friends of mine helped me to discover a new type regenerator. It does not use neither class AB nor class D amplifiers, still outputs brand new harmonically clean, ...

[quote user="Romy the Cat"] In the 2008 I have a few immediate goals:
1) Finalize the 6-chennals version of Super Melquiades and integrate it with Macondo
2) Finalize the “End of Life" Phonostage:
3) ...

Maybe he should have read that instead of Nietzsche:http://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords=daniel+everett+snakes&x=0&y=0A book from an American missionary who was converted to nihilism by a nihilist i...

[quote]Just to clear this up, simply because you have not had an issue, does not mean that an issue does not exist, and that this must be a defective unit.[/quote]I was responding to the comment about the person being bothered by anything in the uppe...

Sounds to me like your switch mode transformer is doing the buzzing. I recently purchased an APC product that charged the battery constantly, so long as it was plugged in. This caused quite a bit of heat and stench, from the hot switch mode power sup...

Well,I did speak with Damian in Technical Support at APS, and he informs me that this effect is something that they have reproduced in their lab, but only with extremely efficient loudspeakers and certain power supply designs in the amplifier. With ...

And so.....
Is the APS now "up to scratch" ?jd*...

Adrian, who knows for sure, given APS "QC" so far, but at this point it still sounds like something you could deal with by properly configuring your various component grounds, lifting and/or bleeding components (3rd wire only) via the dedicated rod. ...

[quote user="Beav"] What I have is a subwoofer made by ACI; no information on the amplifier used other than it uses a two prong power cord, no ground. When I hooked it up to the APS 2000 I got a very loud pitched hum. Taking if off the 2000 an...

Bill, if you have fearlessly ordered a PP2000, and if you actually receive a functioning unit at some point, I hope you will find a way to test and compare it directly to Romy's repeatedly and selectively modified (yet still not correct...) unit. Th...

Maybe you already said it and I am just too tired to follow, but does the APS do OK with "component interaction"? This has been another problem for me, where the thing does alright with one front end component but gets worse with two or more, a...

The returned regenerator did have multiple issues that I experienced: one of them looks like was given unit related and other looks like was purely topological. They are working on it. I am not in position and not at liberty to make comments on behav...

[quote user="steverino"]Again I would ask people who are reporting problems to state whether they have the original PP or the Plus version made in the last few years. I assume Adrian had an original version with a hum problem which was incautiously r...

Well got my very hefty piece APS PP 2000 today. This item is well packaged and weighs in at over 70 lps. You could pull something if your not careful positioning 2000 in your rack. Glad i have my Audiav Crystal rack for this behometh. My loaned 1050 ...

[quote user="Paul S"]Adrian, may I assume that if your unit was finally sorted out, then you would have said as much by now?[/quote]The issue is unresolved. The unit still emits a buzzing sound when it is plugged in. I have sent a few e-mails to APS ...

After many unanswered e-mails, I got word from APS today, who said they have had a few customers with similar issues and that it seems to be system dependent. However, they also said that they were working on a way to fix this that they might have i...

[quote user="Bud"]Sounds to me like your switch mode transformer is doing the buzzing... There is always a turn on buzz, but just for about 10 seconds. The original one had a noisy fan also, to keep it from self igniting, perhaps that is your actual ...
|

I ran quite a few types of gear with the 2000 I tested. It was quiet as a mouse with all of them. I also have extremely good high frequency hearing and if there's anything "unnatural" going on in that range it would bother me greatly. The buzzing...

Among the contemporary ion tweeters I heard only with Acapellas, multiple times, never was happy with the results as the tweeters sounded as different drivers to the enter speaker. Also in a past I bought on eBay a number of vintage ion tweeters – th...

Lx_, I can't tell from your post if it was/is clear to you that I suggested lifting only what APS refer to as the "safety ground", as opposed to the "neutral" wire. In most systems, the neutral is white, and the "ground" is green. In the USA, this ...

[quote user="Paul S"]Any updates from users/sufferers on the "new", lighter/cheaper-to-ship APS stuff? Mani?[/quote]No, not from my end. I've kind of given up on 'upgrading' to a PP+. I've gone around in circles with my current PP2000, sometimes lik...

"Success" equals better except for added hum? How lucky is APS to have customers like this?!?Any dimmer switches within a mile and a half of the system? Any variable inductors connected anywhere in the house? Root out anything like ...

Not exacty a direct response, but I have wondered for a while now if having good electricity as a starting point means one could benefit from simpler power supplies. I mean, how many LCs does one need , given perfect, quiet AC to begi...
|

Hello friends,For long I wanted to address the issues of too few power outlets and improvement of AC quality. I currently use two $10 power strips. I do not have $2000 for APS purepower, so maybe some one can help me start off with the basics. I have...

In the end, only so much can be accomplished with hi-fi until the electricity is sorted out and made to be not only good, but also consistent. Congratulations on turning that very important corner.Disappointed as I am to hear of yet another rando...

[quote user="decoud"]Perhaps you should use the cathedral configuration to make a synergy horn of the entire ceiling: tweeter at the apex, mf a little further down each wall, and bass at the base. Were it steeper it could actually work. [/quote]

As I've said a couple of months ago, I got my APS 700i regenerator a few days ago... I didn't "audio-test" it so far but there will be plenty of time for that later. I've fired it up to see if it's workong properly and everything looks good so far. T...

Again, for anyone who may not know (and not to torture or talk down to those who do know):US electrical systems (along with most others I am aware of) have by code but one main ground that is shared by the "neutral"/return wire (white, hereabout...
