Properly designed components to tolerate garbage power?

Might I ask you: what does it mean? Is it a some kind of mental exercise for you, like the example of the car's suspension? Do you personally recognize the sonic impact of bad electricity in your own playback? Do you have any realistic ways to deal with bad electricity and were able to accomplish better sonic results? The most important: did you personally experimented (or know somebody) who was able to “properly” design components “which are able to tolerate garbage power”? I know a few designers who claim that they design power supplies that are immune from bad electricity. I owned some of their components and I can testify that they have no idea what they are talks about in context of electricity influence to sound. So, I am VERY suspicion when people talk about “properly designed components which are able to tolerate garbage power”. Usually it indicates superficial understanding and experiencing of the electricity sonic influence.

No, i don't know how to design that

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 from yours.

approximately half of all gear i own has at times made weird noises due to interferences of sorts.  some of that gear was from reputable companies like JBL ( active monitors ) which you would have hoped would be able to avoid issues like this.


apparently their thinking is that if it only manifests itself maybe 0.1% of the time it's not a problem.  but if it can have dramatic effect in that 0.1% of the time then it must have some sort of effect the rest of the time too - i simply do not recognize it when it isn't dramatic.
 Romy the Cat wrote:

well i always try to: 


physically and logically shorten the analog signal path


have every connector link balanced and shielded


have every component in the chain use only power supplies with 3 prong power cords and have them all grounded to the same circuit with decently thick cables like 12 gauge


of course that can only enable properly designed gear to work properly.  if the gear isn't designed right nothing will help.

the only time i was able to make a difference is in my car audio setup.  by playing around with different grounding configurations, cable lengths and gauges i was able to reduce alternator whine an order of magnitude.  at the end of the day it was still there - i only managed to get it down to tolerable level.



as far as effects on sound no.  i do not perceive changes in sound itself depending on power issues.  i can only perceive the power issues directly when they produce sound where there should be silence.

no.  i have no knowledge in that area.

most people tend to over-estimate their abilities, so there is no surprise there.


although it is also possible you're describing a different problem from the one they are trying to solve.

My site is not for beginners.

Vasyachkin,

I see, you do not know yet how electricity affects Sound. It is OK. I wish people understand that my site is not for beginners. If you look in future into the relation between Sound and electrical effects then you might realized that your idea of  “properly” designed components to tolerate bad electricity and your association of car's suspension are just a literature based upon unfamiliarity with the theme. Please, let drop any further thinking at my site about  “power conditioning” and where it need to be addressed.

Vacuumstate
fiogf49gjkf0d
I never heard the Vacuumstate. A pair of 300B in the “differential SET” application… Hm, would it sound different then a regular 300B? Juts kidding… The last “SET tandem” that I head was with a pair of 6C33C in “differential SET” pushing 45W. The amps were made by Vladimir Bazelkov, who runs a company Audio Mirror

You heard four of these amps several times at my place running the bass and midrange horns.

Gobel Majestic and six subwoofer
I listened to Gobel Majestic loudspeaker in munich, Gobel is not like other dead sounding modern dynamic driver speakers, it is like old big wilsons (like 2007 alexandria x2) very efficient and very very dynamic.

I think I can say Gobel Majestic + 6sub is very close to top horn speakers.

Which Demo Convinced You?
I hope no one is buying expensive hi-fi components based on YouTube presentations, but one might take steps to listen in person if "the YouTube presentation is interesting". Got to say, available YouTube presentations on this speaker are not at all interesting to me, and sound is turgid in a way that usually means it it turgid in person. Of course, different set up, including amps, sources, etc.  might make significant improvements, not to mention live vs. cell phone relay to YouTube. Amir, what did you hear that moved you to post this?

Best regards,
Paul S

Dear Paul,
I have listened to Gobel in Gobel factory showroom 72km far away from munich .
Two setup was there, one CH Precision Class AB amplification second was Class A Riviera amplification .
Gobel is very different to other modern dd speaker systems. 

What I think is two designers are different in comparison by most modern system designers, Oliver Gobel (Gobel Speaker Designer) and also Wadax digital designer.

Audible Strengths and Weaknesses?
Amir, you seem to get around to listen to a lot of hi-fi systems. Of course I hope you will tell about the sound and the communication of Music from the equipment you auditioned that moved you, and moved you to post about it. "Different" might be anything. Different how? How did it sound to you, based on what Music, etc? As I have told at GSC, when I used to go to audio shows I would seek out good sound and take notes, because bad sound at a show might be for any reason, but good sound always means the gear can do that.

Best regards,
Paul S

Dear Paul, please let me time , I will back to you soon and write a long post about Gobel Majestic speaker.
I also had not enough time to see all recent videos of Romy, I will see it soon.

Gobel Majestic and Six Subwoofer
Dear Paul,
Before introducing any description about the sound of Gobel Majestic speaker I should say the best way is going to Munich and listen to thoes monsters in Gobel factory showroom. Oliver Gobel is very kind and gentelman and warmly host you.
First, I am not in a situation to recommend any thing to audiophiles and I just share my listening experience here.Second, I just speak about Gobel Majestic with 6 subwoofers not other models of Gobel Speakers.High end market is not happy because there are many companies who claim/advertise and spread non-sense information and also their prices are high. In this market finding good equipments is not easy.I think In this market less than 25 (less than 5% percent) audio companies are my favorite, This does not mean my favorite companies produce exactly what I like No, those 20 companies produce good/balance (error free) sound that you can listen for long time.
There are many important things in sound reproduction but in my opinion The most important key is “dynamics” . As you know most low efficiency dynamic driver modern speakers trade off dynamics for better measurements. In this market the Gobel Majestic (+ six subwoofers) is very very dynamic without altering tone beauty. In my opinion The art of Oliver Gobel is finding good balance between “transferring musical core message” (expressivenes) and high fidelity of sound (like dynamics, transparency, …).
I think Gobel Majestic was not happy with CH Precision amplification but even in those condition it was clear that Majestic is a great speaker.

Low power tubes SETs or even 20w push-pull are not enough for Majestic but those monsters do not need huge power, I think 100w (for midrange) and 100w(for bass) class A is enough.
Gobel subwoofer is sealed and active so it does not need extra amplification.
Gobel Majestic is very very impressive at first hours of listening , huge Power , nuclear Energy, Big Scale, super transparent, perfect dynamic range, good bass, fast transient , slow decay … all things are good but the most important thing is Gobel Majestic is very good in transferring musical messages. 
Long story short, I think I like it .
