Paul,It has also been my experience when dealing with the PurePower that it was sensitive to which circuit from the main breaker that it was plugged in to -- ultimately why I moved to a dedicated line.It is worth experimenting having the stereo conne...

Like anything else in electronic design, it is all about compromises. No resistor is an ideal resistor and no audio circuit is an ideal audio circuit. I remember when Meridian Audio came out with their active digital speakers in the mid-80's, and I h...

[quote user="Paul S"]it seems like a miracle that two people familiar with the score could recognize "it" and agree on it, via any sort of playback whatsoever ... we tend to focus (more or less) on the parts we recognize as Music. [/quote][quote user...

[quote user="rowuk"]This is one of the aspects of being a "conductor". Very immediate sound, little early reflections or concert hall - everything is "overly" dynamic. When we compare this to being in the audience, each instrument group behaves in di...

You are correct that tungsten must be welded, as it will not wet with commonly available solder. Given the wire gauge and application to electronic circuitry, you might weld to a solderable metal on the ends, but for the use as a speaker wire, I foun...

With the talk about fuses, I think I'll chime in to mention that I did several years ago a lot of experimentation with different metals and their effect on sound, which was based on listening sessions with myself and a group of music lovers and musi...

Romy, I was delighted to see your video monologue, and I look forward to following along your new journey.No speaker can reproduce the reality of a live musical event for various reasons, and all speakers are by their nature a conglomeration of engin...

When thinking about how to clean records -- even brand new records -- it may be instructive to remember how records are physically manufactured. This is a nice video that reviews the process:https://youtu.be/awmA-z6EgrE...

I'm with Paul on this one. If the product exists for a reasonable price, I have no problem with buying it. I only resort to DIY when the product that I want doesn't exist (or it's too expensive). Frankly DIY takes a lot of time, and there's plenty of...

The way it is described, I have to agree about taking the Pure Power to a trusted local repair shop to get it scoped out.I will just say again that repairing the Pure Power seems to fix the problems, for those who have been able to get their unit bac...

[quote user="N-set"]
They have figured out a way to
eliminate this but it requires making a new PCB to replace one in the
PP2000. So they say they are going to make these and hopefully the
replacement PCB will be given to me in a month." [/quo...

In regard to the noise issue I had with my Pure Power unit in the past, I never noticed it with my tuner or other components, but I mostly listen to the phonograph. In particular the Decca cartridges are incredible as antennas and seem to pick up all...

Jarek, When you say "not 50 Hz hum" it reminds me very much of my troubles I had with my Pure Power 1500 -- (before it "blew up" and needed to be repaired ... ultimately replaced with a new PP 2000 plus by Damien) -- but in any regard, the hum was ca...

I can only suggest to keep calling them. The product itself, as we all know is outstanding and makes everything else in the category look like garbage, but the service has always stayed at the level of a one-man operation. If they can get their servi...

Agreed. I also had this issue with my Decca cartridge using the Pure Power and physical separation works well....

Every resistor, capacitor, tube, etc. are just physical devices that are optimized to come a bit closer to an ideal device -- a wirewound resistor may represent an ideal resistor, but it has inductance, capacitance, and other electrical and physical ...

[quote user="Romy the Cat"]PP does inject very positive qualities to sound and it is in part might
be because it addresses some of intricate electric problems but we, or at least
I, do not know it with certainly. The claims that PP manufacturers ma...
