What an idiot I was. I made a few phone calls and inquired about a few high end ceiling fans. The smallest 6” BigAssFan cost about $3K, I need two – so it is kind of too expensive. Some other best fans are around $1K each. They all promise arou...

Steverino, they are all reasonable questions, I do not have answers, I have some hypnotizes that might look unto. It does appear to me that the change that I observe are not electricity related, at least not the electricity as we understand it. The e...

It is detailed elsewhere on the website, but when I sent my PP2000 to be repaired, I received endless promises. It turned out the company was going through a major crisis with a Chinese manufacturer and distributor trying to usurp the brand. They eve...

Yes, you are right, the voltage divider from 6.3V across 47K and 10K resistors shall give not 0.9V but 1.1V. However, the numbers that are in circuit are not something that I saw in my dreams but the actual numbers that I measured. I might presume th...

Ok, I think it is a good time to deal with room acoustics. All infrastructure problems are set. The Midbass horns are underway; the electricity will be investigated but as now is addressed by PP2000. Macondo and Milqs are inhaled, the system is up. I...

Bill, have you been using and reporting on Romy's unit, while you wait for your own unit to arrive? I ask because if this is the case then we still have no evidence that there is a second viable unit out there.It sounds like the AC/DC converter/char...

I got a contact from PurePower this morning and they requested some times to look into what is going on. It was not exactly pleasant that they took my behavior as my personal attack against them – it was absolutely not my intention and I have no pers...

Yes. Their is a direct correlation between surge current and dielectric materials dielectric constant. The voltages in question are high enough to use a thick dielectric material and just as with the effective resistance of the capacitor, there is a ...

To recap what I have said before, the issue is bad electricity, which makes your stereo much like aliving thing with tempermental moods. The same way that a steak can change from a sizzling, juicy tender delight to a cold greasy lump after being chil...

I am talking about the fans and the capacitors. I have a PP2000 and the more you load it, the more the capacitors "whine".Nothing from the speakers themselves. It is a pity that cooling is not passive taking into account the efficiency announced. I g...

I do not know, Meiko41. I am not a speak-person for PP2000 and I am in very same boat as you are. They told me that they have a modification that would make the fan more silent and they promised to send it to me… a year ago. Frankly I did not insist ...

Thanks, Bill, I do not need it yet. I estimate that I am a good 2-5 weeks away from the time what I might just stat play with my playback at any more or less refined level. Also, I would like as well you to compare your PP2000 with mine, not that I s...

[quote user="nl"] I have used Russian high-gm tubes like 6C45 in amps before, including single-stage designs very much like Romy's single-stage Milq. These have many attractions. However, in my experience it just didn't have the tone. Jim de Kort of ...

A few words before I lay down the facts. Over the last week I got a number of signals from PurePower that I shall not defame their products. Their marketing director Bob Rapoport – a certifiable idiots – informed me that...

It is confusing, but the NEUTRAL is not only "referenced to ground", but in properly-designed components it is THE reference to ground. Too bad most commercial hi-fi gear splits any and all grounding, at any point in any circuit, between the ne...

Thanks for the info Meiko41 !At what load (the percentage on the display) does the noise from the capacitors becomes annoying ? Do the fans stay always on or they kick in when you reach certain temperature ? I gues...

[quote user="Romy the Cat"]I was thinking about this: how come that driving 6C33C (in fact driving anything one can imagine) the 6E5P was very fine but driving 2A3 it was dull like hell. I opened the amp and tested all – everything was perfect but th...

Another thing to think about along with larger batteries for the PP is the charging process, which needs to be "shaped" to make best use of the particular battery or batteries, including maximizing battery life. Also, if the stock PP2000 uses se...
