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...

Thanks for that collection of negative information on the DSP effects on music, Romy. I'm not a contributor to your site but you always put me in wierd situations with your unusual findings. For example, I have always used a DBX digital crossover in ...

PFC is a function of adding Xc using capacitors to bring the current in the circuit downwards.What you have is an inductive load giving a lagging PF eg a simple motor gives a PF of 0.85.Thus the inductive element can be manipulated to bring it from l...

So after a month I continue to enjoy what the inverter does.I have found that the time one gets from 400 Ahs with the inverter's meter showing 640 watts usage is about 1.5 hours - you could get two if you let the batteries run down further but I figu...

The inverter has a meter that says 0 watts when nothing is connected to it - other than the batteries.As soon as something is "plugged in" it says 40 watts.GIADEL says the unit uses 1.2 amps/14 watts at idle. I guess it does not really turn on until...

Hm, that is a good question. I honestly do not remember. The 6ch Super Melquiades has 7A fuse but I have no memory about the fuse I used in single channels amp. During the assembly I used the lamp fuse – that is given but in the final version I just ...

That is very interesting. I have a distortion miter plugged all time into my power lines and he last 2-3 days it went out of reservation. Literally it goes absolutely crazy suggesting the there is huge amount of noise in the lines. I did check the me...

Good question, as usual, Decoud. No doubt it has something to do with the very unusual recording, plus my own penchant for "getting involved" in the music according to what the recording and the system will allow. It was not an LP, after all, but a ...

A Seminar presented by Greg Burnett at Audio Fest 2004, Colorado Audio Society

Why are audiophiles interested in FM radio? Because the quality of FM audio was satisfying until stations began to compete with each othe...

The point that am trying to make is that the subject of the “home use“ driver vs. the “pro use drivers” is a bit complicated and the thing are not so clear as you, Stefano, is trying to present it to yourself.[/quote]Tha...

The ideal horn system would have to be well integrated into the room, acoustically as well as optically/cosmetically. As far as a commercial venture goes, I believe that Marc Henrys "La Grand Castine" was already (except for the ULF dipole panel) ver...

OK, my carpenter has finished today his part, go his final check and the project is officially over for him. Some minor things I will ask him to correct next week. Also I will ask him to put a narrow slightly darker border between horn and the wall, ...

[quote user="Paul S"]Thanks, Scott L. I get the math, and no doubt hearing is believing. Still, I do know for certain that "a driver" can be influenced by a defined amount of trapped air in an enclosure, at least as far as the sound that comes from ...

[quote user="anthony"]Do you have a
“final version” of the schematic anywhere? [/quote] I think that the one you
have might be recognized as final. The Rev2 was without DHT in MF and Rev3 was
with it. I did not do anything else with the amp af...

[quote user="Welborne"] 1) There are hexagons on the schematics marked with A, B, C ...M. What are these? Are they testing points or they carry some meaning? I can't find much info about these here. [/quote] Yes, the hexagons are test points. Do ...

Thanks for the wise, simple instructions, Roman, also useful to others, I believe... that's what I actually do since I - 'twas ONLY 15 months ago... - became conscious of the limits of my tuning-by-ear and got my IVIE IE-30 with Class A measurement m...

Yes, I know this, I just didn't understand how you were measuring current... I am familiar with Ohm's law, but didn't see where you were getting enough info to "buil...

Hi Daniel, great initiative! More of that :) Can you tell us more how u measured??Like loudness, distance, settings? I know that Fuzz likes to sweep too short (0.1 sec. logsweep) and allows many crappy windowing settings...Maybe a nearfield (close to...

I'm only aware of PS audio as an alternative. I wasn't crazy about the original power plant but they introduced new models recently which may be better. (I did not get favorable results running my turntable through the PurePower and I have one of the...

That spike went away.Did not seem to have anything to do with lighting. Completely mysterious - it just went away and has not returned.I have not done anything with the ground rod idea.I did listen with the ground wire unplugged - a plug with just a...

Below are some images that show the locations of the various filter caps within the amplifier chassis.The big cap for the First Stages is located directly below the 6E5P tubes...The big filter cap for the Bass Channel is adjacent to the Bass OPT (pee...

It is in away unfortunate that the new dedicated line and the new PP3000 come right at the same time. I am tell you that since the PP3000 and dedicated line I have no single bad electricity day and playback behaves very nice. I just try to establish ...

[quote user="manisandher"]Sorry Romy I can't help you - I've never heard of this before. But I'm certainly tempted to explore further now...(Incidentally, my new PP2000 will arrive tomorrow.)[/quote]You can Google the “Legally Slow Down Power Meter” ...

[quote user="Romy the Cat"] Tim, it is all very interesting and I would like to learn about the Proteus’ inner wire juts for a sake of general education on the subject. However, I would not go for a duplication of what Purist did. Doing it you will s...

[quote user="manisandher"]This is very disappointing to hear.
But in a way, it makes little difference to me. I had decided that I would only use the PP2000 from battery power when listening to music (or making vinyl transfers to digital). I'v...

I was wondering what is coming out from PP2000 that makes one unit affect another. It might be radio and magnetic stray fields. Last night I took my gauss meter and was sniffing all around my PurePower regenerators. I was not able to see any signific...

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 ...

Hi Romy,The builder regards VR1 more like an "offset to 0" adjuster than a bias control for the 6E5P since its working range is quite narrow. He asked me to know from you if along the 6E5P's lifespan it needs further adjustments at VR1 or if a single...
