Romy,
I've been storing all my digital music on a computer located fairly far
from the audio system for quite some time now. You've brought up a few
issues that are worth discussing.
1) Storing the digital stream - I assume you mean either (...

Last night I have an interesting “event”. I accidently unplugged the PP from power line and did not know about it. In a couple hours I realized that the lights on my equipment that all time on are off. So, the PP buttery was drained out. Interest...

[quote user="JOHNR"]One of the things that I picked up in this thread is the fact that if you use 2 PSUs in series, the sound degrades.This is typical of one unit generating common mode noise and this adds to that produced by the second unit.Even if ...

[quote user="drdna"] It is not exactly correct. There is 60 Hz hum eliminated by lifting the ground to the amplifiers. The neutral is connected to the ground prong and chassis in the amps, so I assume it is setting up a loop. However, there is a seco...

RowukI have fully read all pages of this topic (mad mad mad electricity) two times and I know good sound does not come from pure sinewave .I should say I am here (like a student) to learn more and I do not like spread my in-complete BS ideas here.I r...

user="steverino"] Later after the PP battery was replaced hum disappeared
forever.

Interesting. What made you
to replace the battery? The reasons I ask is a because an old buttery would not
be different for powers supply then ...

[quote user="Romy the Cat"]Do you personally recognize the sonic impact of bad electricity in your own playback?[/quote]no, not in the sense that i assume you mean it. instead i have my own beef with bad electricity, which i suspect is different fro...

I think the truth is somewhere in the middle. I do not believe that PP2000 shall be treated as appliances. Purepower units are complex machinery and they have to be serviced only by Purepower technicians. I would never agree to have an external pers...

In my case, I have not observed any fluctuations in sound quality other than those resulting from my own state of fatigue (maybe they are doing something right with power generation/distribution over here... I don't see many complaints coming from ou...

Thanks Romy, this seems the most practical solution. I will connect a wire to the gnd terminal at the phono inputs and see where it wants to go: power strip, PP or wall ground. I have two more questions:
-- the cable you run from...

[quote user="Paul S"]Alex, I "invented" and built my own power cables from scratch, using sleeved, solid, 12AWG Cu magnet wire, as I explained to Jarek, way up this thread. If buying pre-fab cables, I would first consider Speltz. As for "oiling" the ...

[quote user="JOHNR"]You should take care that you do not daisy chain the ground leads.[...]A system that can work well is to create a single node or terminal where all ground leads are terminated. This terminal is then connected in turn to the elec...

I must say I've never came in to intimate contact with cables and avoid it untill I can, so yes all my arguments are theoretical.By amplifying I ment of course voltage, not power and ass-u-med that the external noise as well as the cable distortion a...

My journey with computer audio offers me reason to be optimistic. I think it is like everything else in the audio chain. Everything counts. Keep it as simple as possible. The power for every consumer is important. Keep the number of parts and transfo...

This post might be called “the surprise of a new suburban idiot” and it will be not too far from truth. Still the whole idea gives me some much pleasure that I would share it, no matter how pathetic it I for a person who live in suburbs for a w...

I think I am correct, but the problem is directly related to loudspeaker impedance. I did the first round of calculations by hand and when I got the results I searched the web for a calculator that someone has made so that I did not have to write it...

[quote user="Vance"] Romy, it takes several months for those blackgate caps to fully calm down…. [/quote]
Actually I take more like several decades and then 5 years after you each time shut down the unit for 5 minutes. I am known to be not a huge fu...

I do not know, I always have difficulties to talk with audio people about those subjects. They seems to have very strong and very definitive position how different driving tool affect sound of their timbales. The most ...

Considering the employments I would like to make in my installation after the floor will be done and the system is re-assembled I am very much thinking about some kind of new cable management solution. I have 21 powered components in my playback syst...

Well, this concept of Defense Mode is good for superficial explanation (or for selling to ourselves own justifications) and I use to use it in past but I do not use it for a few years as unfortunately it is not what it is. The correction of “the wron...

Well the marketing power can change dirt into gold, we all know that. I have no problems with manufacturers who offer "such" units. We, the customers (especially here in this Forum) are fixed on the quality of sound. Some years ago there was a meetin...

I have been adding and reconfiguring gear recently and I will be needing a 6' digital cable very soon, when I add batteriy power, so I just went ahead and bought one of the "Synopsis" remainders Romy mentioned.This $5 discontinued Belkin blue ca...

user="anthony"]I've just done some calculations for power loss versus
cable gauge and I think that with that length of cable that I would be best off
with as low a resistance as possible. It seems to be an absolutely
overriding factor. I...

(Romy feel free to move this post)[quote user="Paul S"]N-set, I understand you do not mean to hijack the thread with the Axiom, so I actually tried to make generic and/or thread-related observations. I don't know the 6E5P, but generic issues with sp...

Romy,I don't recall seeing a bypass switch per se, and don't know if the other control functions ofter something equivalent. I haven't really experimented with the 3000+ much, as my system is in a state of influx, with addition of items (entire cabl...
