The Big Deal for me this year was programing, in the sense that I now have more ready access to more music since I figured out the correlation between (measured) record thickness and arm heigth (VTA). Now I just put the record on the platter, adjust...

You can find a brief description here: http://www.salicru.es/index.php?id=1678&L=2 My unit is a RE-1009 2T, which means has double transformer, but it's not the extra noise filtering model which they call NS. Looking at this I'm quite sure i...

A month or so ago I came to an occasion to fish a large isolation transformer. It is not that I believe in isolation transformers as all my former experiments with them delivered quite gruesome sonic result. However, since the APS people are still no...

Something very interesting happened today in my battle with the incessant buzz in the PP2000. No, it did not go away unfortunately, but I learned something new.Perhaps inspired by the recent discussions around the original pressings, I decided to spi...

[quote user="Lx_"] Well, this is consistent with the behavior I have. I can hear electrical devices behind the PP, especially those of the switching PS type: computer screen, laptop charger, DSL box, printer, SAT decoder... Good luck finding electron...

[quote user="Paul S"]Joaco, all this will probably be moved back to the "Electricity" thread, which is not really an APS Forum, as it has appeared for a while, now.

Dear Don C
A few facts you are missing, and a libelous statement that need correcting.
The PurePower product was designed and manufactured in Canada starting in 2003 by Audiophile APS Inc., years before any production was outsourced to Taiwan. ...

Well, my research of the subject leaded me to talk with their distributor. He turned out to be very much clueless and loaded me with a pile of incredible BS. I spoke with the guy at the manufact...

I have come across this company mentioned in a preview on '6moons,' and the information on the company's website suggests that this is in theory really a complete solution, and one that makes sense even to the non-engineer that I am to...

I looks at the statistics page of my site and it looks like there were zillions Netherlandiams visiting the site. I wonder why they don’t say how the Kemp regenerator sounds. The judgment part? Well, this is an easy part....

Well, if I stop to post in this there is does not mean that the problem is not there anymore and with a new few weeks I hope to attack the electricity problem again.
Firstly the new version of APS Pure Power regenerator is coming and they are about ...

[quote user="JJ Triode"]Romy, take a look at EML 30A and its cousins:

Yep, thanks, JJ. Still the EML 30A has a lot of gain but it has also very high plate impedance as well. As much gain w...

[quote user="el`Ol"]David Wilson says about the WAMM:
Atkinson: What range does the electrostatic unit cover?
Wilson: It operates above 5kHz. And it operates at a very low level. It functions primarily to provide part of the leading edge of high-f...

[quote user="Paul S"]... there really is no "affordable" universal solution to AC power correction from an electrical standpoint, especially not for hi-fi, where amplifier topology might be just about anything, and these amps might be running ri...

I have ais very much the same configuration as Adrian has and I find work the best for me. I have PP plugged

The PP shall not work with lifted source ground, it g...

[quote user="Romy the Cat"]Well, I do not care one way or another and I truly have no “concern”. I have my drivers; I think I have some spare – so why would I care about new productions. [/quote]Romy, I am very pleased that you have your drivers. And...

[quote user="Paul S"]Truly desperate scofflaws might find themselves so annoyed by the hum that they lift the PP2000 AC ground connection at the PP2000 chassis and run that unit's ground only to a dedicated ground (with a lower impedance, of course),...

Well,
I have to tell you, Meiko41 that I was pleased to see that a local guy got a new PP2000. I kind of on the verge to get another PP2000 and this was a good preview what newest state of the PP2000 is. Even it was very clear the with PP2000...

Well, in my formers listening

SS aps to pump room with 20Hz low pass filter. Do not forgets that the filter
was sitting on transition slope and it was 0dB at 20Hz and ...

First, it may be more important to have a
consistent waveform, which can be regenerated from the Tesla battery. If we
have a consistent waveform, then we have something to work with to be able to

It looks like PS Audio release their new most powerful
regenerator P20. It is 2KW, $10K and they sell it honestly: free in-home trial.
As readers of my site know I am not a proponent of type regeneration that PS
Audio does. The Class AB regenerati...
