No surprise, the biggest problem when shopping for "suitable" amps is getting a bead on the sound using systems featuring the truly BAD "high end" speakers and ancilliaries. Still, I actually found something that might be acceptable; but units are c...

[quote user="Romy the Cat"]First of all I need to admit that I do not believe to people who claim that Purepower produces noise. My units are completely silent and I know other people who have completely silent Purepowers. I have no doubts that the p...

This weekend I decide to take my FM where it should be. I ran ~125” and installed a dipole on the roof of my building and serviced my tuner. The result was as expected but there was something unexpected. Along with all normal benefits of better anten...

I want to let Paul S know that if he found our QC to be not up to his standards in the past, that he give us a second look. Many of our response timing issues of the past few years were the result of time delays between our Canadian personnel and our...

Here's a decent attempt to boil down basic "ground" issues. Generally speaking, according to best practices, grounding one's hi-fi is a systematic attempt to equalize the ground potential throughout the system at "zero". Again, phono stages are harde...

We are so overly familiar with the music of the Romantic era (and to a lesser extent with some 20th century orchestral music) that we tend to overestimate the importance of dynamics overall in music and in listening. Obviously, abrupt and frequent dy...

[quote user="Paul S"]For a while there, every system change I made that "improved" the sound also limited my musical choices. But the most recent round of changes has had the opposite effect, much to my delight, and I have been amazed by how well gre...

The following reflects the current state of my understanding, and in some cases, my opinion... I welcome and very much value other points of view.Max, regarding B&W and Color : Actually we do agree here ; I did not write (nor mean to suggest) tha...

Many years gone now, I have tried to keep in mind the sound of live acoustic instruments and voices as I tuned my hi-fi system, as it and I have evolved. So far it seems that there are an infinite number of ways to "move closer" to a constantly...

It can be a bit difficult to get across the full breadth of one's meaning. I had a few perspectives in mind when i wrote the last paragraph, one being the (i don't want to sound too pretentious, but for lack of a better word) enlightened audio...

Romy,
No, the DAC was not set at maximum level (for best sound) while Cyrille listening to the system. It was set at normal volume for the whole system. When Cyrille dropped by, I was showing him the Field Coil open baffle speaker system which con...

[quote user="Romy the Cat"]The concept of self-testing boot cycle is nice one but it for sure could not be done during the amp booting. Some tubes do need to warm up and reach the cruse temperature in order to be tested, some do not. Some tunes (lik...

Well, I remember being "astounded" years ago by Crown's "DC" amps' LF capabilities with an ever-widening range of LF "tasks". More recently, I was "impressed" by plate-amp-driven subs at THE show. I haven't gotten to ULF with my system yet, but I p...

I do not know what is meant by “close bottom” or “open bottomless”-- please expound?I do not know of importance of enemys death to this topic. There is a long thread in the subwoofer section of "devil audio" about tapped horns. John mentioned gettin...

Haralanov, it had to say, I think it would be all depends how he use that MF driver. Do not forget that this MF driver, I still insist to call it Lowther has very extended HF. That is different type of HF that is coming from “cigarette filter paper”....

Paul. GSC = goodsoundclub I have worked with Richard (pure power owner) and i know the problems of customers but i think paypal is a good way to shop from Richard. Ask Richard to send you video from the unit before paying to him. Recently 3 or 4 pure...

Well, if cost if no object, why not put everything on those cool SRA stands? Besides, Mike probably uses the most affordable version, anyway...Of course those will not in any case address all sonic intrusions, which include not only structural ...

[quote user="drdna"] So what are the effects of good electricity of the PP2000? It may be a good idea to look at the frequency response and harmonic distortion of the system to see if filters in the Macondo speaker system may need to be adjusted now ...

[quote user="drdna"]Okay, today I hooked it up and have spend some time listening. The change in my system was very dramatic and positive. First of all, it seems suddenly like a good electricity day. The noise floor dropped out. The timbre of the mus...

Using the PP2000 has been a very interesting experience. Immediately listening I am NOT struck that it is the most wonderful improvement ever, which I have said before is a GOOD sign. Usually the seductive sound changes are colorations that are enj...

[quote user="Paul S"]"Success" equals better except for added hum?[/quote] Well, I am sure I can get rid of the hum, so then it will be all good. In fact, I know I can do that just be unplugging the PP2000. That is not an optimal solution of course.

A bit of the background. Before acquiring the PP, the whole system had been moved from it's previous location in Gdansk to a new one in Warsaw. New, busy city, new apartment, new electricity. Straight after the move and connected to the new house...

It is the second Romy, the noise is always present. There was always a little noise but when I had a soundsmith strain gauge system arrive, I was expecting not to have any noise. It is a hum free device. When I installed it thought, there was a buzz....

Yesterday there was the worst I can remember in my long-lasting with electricity. I mean it was not just bad it was beyond any description. My preamp has 126 steps (near a db per click) and during an average electricity day I listening it at 50-60 sl...
