[quote user="N-set"]IIRC, Viborg uses what they call red copper, which is probably red brass - a high Cu content brass, quite a bit harder than pure Cu. Visually and under a few strokes of a metal saw (I wanted to check if this is not a plating) beha...

I bet Taiwanese got tired of getting paid cents on dollar (and usually late) for product they developed and manufactured. The real guilty character in this all affair is Romy the Cat and his rumblings . Without it Pure Power would be selling as it wa...

[quote user="decoud"]It seems reasonable to begin with the science -- as a preliminary to listening -- but I do not follow the logic here. The source of the vibration is principally the floor: the table should therefore not be coupled with spikes but...

To be practical, Pure Power needs to sell the design or system to some company that has the capitalization to market and improve it effectively. Years after their move back to Canada we see no change in their basic operation which seems to consist of...

I like your comment about LF being too dry and this not being because room is untreated.In the past, I have tried to "wet up" sound by making room more reflective ("live") and I am guessing that your room is fairly live now as untreated rooms usually...

There was a cool Russian-made tube GU-48. It is high-gain, high power pure direct heated triode with 300W on plate and 10A on carbonized tungsten cathode. I did not hear but it looks like something in the class of RCA 833 tubes. I think Japanese sel...

Romy, I don't think we're in any major disagreement. It's clear you have a good operating point and performance indicates this as well. I did a "normalized" model of this with the 2A3 and 45 and it specs well. All I'm suggesting is that all early an...

[quote user="steverino"] I'm not surprised at your disappointing results as I have experienced the same with a variety of power filtration or generating devices. Your surmise is correct that such devices work much more easily with AV equipment or com...

If i am not mistaken It seems Most High Power UPS in the market like APC or ABB are not good for high dynamic loads (high crest factor like Music signal) and the load transient response of these UPS is not very good at rated power. APC , ABB and ... ...

Either my ears have gone bad or I must be the luckiest user of pure power regenerators. Have been using three for four months now and am still bowled over the improvement in my system. No matter what time of day I listen it sounds superb, but I do no...

I just had a conversation with the guy who runs this JPS Lab. I did anticipate much more idiotic presentation, similar to what they have at their web site. To my surprise the gay was rational. It is not that I agree with all that he was saying but it...

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...

[quote user="Young Skywalker"] I have been intently following this thread for many years and this recent update is very encouraging. I hope that the Pure Power people can deliver on their promise and that the sonic outcome meets with your objecti...

[quote user="steverino"]FWIW I got my own PP 1050 a week ago and am pleased with the sound. It is the first active device that sounds as good as or better than my jury rigged passive filtration. Thanks Romy. As for chaining devices, I tried plugging ...

This subject is interesting but unfortunately there are more options then time in life to experiment with all of them. The idea to use fatter cable is right atop of surface. It is not about current caring but the lower impedance of the cable. Remembe...

DA, looks like very nice and lucid assembly. How do you like the sound of the thing? The output stage 200mA /187V. It is a bit too small but I will do. I do not know what the gap you have in your OPT. If it is limited to 200mA then stay there, you ...

my own experiences with different
systems and environments.

[quote user="de charlus"]Due to this thread, I called the friend upon whose boat I heard the Vox Olympian in order to find out precisely which DCS DAC he was using with his TLOX to get the sound that I found so remarkable. It turns out that whilst th...

It was an interning event last night. The sound turned incredibly bad from electricity perspective. I did not have anything like this for a year or so it was very bad and it was clearly electrical. The PP2000 was workin...

I called to Audience and I spoke with their sales manager.

Richard, my only "motivation" is to keep the light on and my eye on the prize. Sticking just with recent events, of the 3 units Bill Gaw just dealt with, either 2 or all 3 of them failed to self spec. Bill returned 1 of his own 2 units to you for se...
