[quote user="N-set"] You always repeat that you do not listen to the power supply thanks to your "isolating" PS philosophy.This is a super attractive thing worth all the blood, sweat and tears! But then at the same time some disturbing notes come tha...

[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 ...

Ok, it took 2.5 hours to mount the transformers and chokes. The transformers above are filament transformer and high voltage transformer. (The super Melq has all high voltages coils as separate transformers). The 3 chokes above are input chokes for f...

Rob and Romy the Cat,Thank you for inviting me to discuss this subject. Allow me to reply only to the main points raised, due to the present overload of work. However I will try to answer, later, to any specific question on the subject. First : - My ...

[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 ...

Absolutely flat response will usually sound as you've described it; listen to your ears. If you are hearing the opening bass line of "So What" via the sub, you must be running the sub pretty high in frequency to compensate for lack of mid-bass. From ...

With interest I read the posts about the mains / power and the effect on hifi gear.
The conclusion why and how electricity thus have an impact and the overall sound of our system is influenced by it is actually quite simple.
Generally the mains is ...

Was talking with various audio people about the 6C33C I was amazed that people are so clueless about this tube. The people are so filled with some foolish prejudges and faulty notions about 6C33C that I deseeded to put together a brief “6C33C user ma...

Jessie, I hope you do not mind that I pulled it to the forum explicitly dedicated to the Melquiades Support.
5-channels Melquiades is ...

Ah, Amir, did you consider ever that amount of pp generators can create a critical mass of them which advertly affects sound? With all seriousness I hope you do not use the bulk of your generators in the same environment at the same time. I impor...

Those all things take too much space and the new amp for the “fundamental channel” does not really help the situation. I decided to convert the Super Melquiades into something that would have smaller footprint and position the control amplifier unit ...

Brad, I heard a KR years ago, only remember it was not the typical "no-feedback sound", which I think of as clear but flaccid and no push. I agree that "feedback" can eventually ruin bass, and more, as I mentioned earlier in connectio...

[quote user="JJ Triode"]Romy,Try running the left and right signals from the stereo arms, one at a time, into the known-good mono phonocorrector. If the problem is not present then you know the stereo corrector is to blame.Are both left and right ch...

Paul S wrote (originally posted in the thread discussing noise cancellation for Romy's HP servers)http://www.goodsoundclub.com/Forums/ShowPost.aspx?postID=12957#12957"...Jessie, are you saying that the RAID system is "quiet" with respect to regular o...

I still say you will get the same "effects" if you current source a low voltage supply. Or, easier, put an inductor in series with the windings after your filter cap.The way I look at it is that the voice coil is the primary of a transformer; the cor...

Hello all , i know this topic is almost about pp experience but since im experimenting with electricity i like to share some thoughts here . I builded a dac using very high quality components . As you know the power supply is critical . So i decided ...

A typical switching supply does not evenly load the input (sinewave) power source and can create some dirt on the AC line (Paul's "backwash" statement??). Depending on many variables, the amount of contamination the switching supply could contribute...

And you are right that it also has a regulator within the power supply. This is stated within the owner's manual but it would not allow me to copy it. They use rather convoluted language. Maybe this is the result of translation?To quote from the r...

Hi Paul,It's more a buzz than a hum. It buzzes when I put either amp on. ie: at ~30% load. I have not tried other loads since I don't know what would be a appropriate load to test it with other than audio equipment, of which I have nothing other than...

Hi Romy,What a busy year just gone! Finding enough time to just sit down and get the DSET's going has been impossible, but I have time now and have started the process.At the moment I am introducing some high voltage to the first amplifier chassis, ...

Paul,I agree 100%. Well sort of.....Can the idea of the overengineered, atomic reactor power supply with water cooling really offer someone just interested in great music a "better" solution?I think for many, the technical superiority is at least as ...

...to call in if you ever did get to Aus. There is plenty to see and experience here, and the weather is great just about all the time. A critical ear applied to my efforts would be most welcome.

Thanks for the extensive reply. I wish I knew exactly the use the preamp is doing of them and if they could be safely replaced by those alternatives you mention. I believe they're regulators within the power supply. The problem with them is not burni...

What connection do we have considering the spectra of signals on the mains and sound quality? What data do we have on what part of "mains contamination" affects sound quality? What data do we have on how power supplies should be built for the 21st ce...

How about lead acid batteries :-)Only half kidding - they would be cheaper than the caps and just think, you could finally ditch those AC power troubles away.Also the amps would adore the super low impedance power supply... Still, what with that enor...

The fullrange Milq will be built in an oversized chassis with the intention of adding maybe two or more channels down the track and perhaps some line level crossovers. So I will up spec. the mains transformers so they can handle a larger draw and wi...

I do not know what you are trying to do, why do you need the Lynx card, why is need to be modified and what does it mean “powered individually”, the people looks like sell power supply and they push the notion of individual power but no one said that...
