Audio Science Review Tests and Amplifier protection systems

Hey Alan

I have just been banned from ASR. That guy BD Woody thinks I'm in New York, Amsterdam and Australia. One of them was right.

Its so funny. Amir is a total narcissist. He can't ever be wrong. His methods are stupid and he twists and squirms trying to justify them. Amir is a jerk and ASR is a joke..

You are doing great work and I'll be buying some amps soon.

Ciao

Hi @JasonWells and welcome to the forum.

Yes, I have been watching whats been happening. I can only shake my head in dismay. Its what Amir does, he bans anyone that disagrees with him. A very insecure individual and frankly technically incompetent. His responses to you are typical of what he does. Evasion and never addressing the points. Trying to discredit you and myself was his only option. Followed of course by banning.

He banned me because I criticised his speaker reviews. He banned Doug from Soundstage for the same. He banned Erin from Erins Audio Corner because he was doing a genuinely good job of testing speakers, unlike Amir.

Don't worry, there a only a small number of vocal fan boys that follow Amirs every word. I just ignore the place now. Amirs tests are so limited in scope and flawed in method that the information tells you virtually nothing about how a piece of kit might perform let alone sound. He actually thinks that SINAD into 4 ohm resistive load is all you need to know.

I think what annoys me these days is not really Amir, everyone knows what he is like (arrogant egotistical bully), but that what he is doing is just re-inforcing the view of ardent subjectivists that measurements are of no relevance. This is wrong, but using simplistic single measurements such as SINAD and thinking that tells you all you need to know is really dumb. The subjectivist viewpoint is 100% correct in this respect. Unfortunately what he is doing is so inept and limited in scope, it tarnishes the validity and genuine usefulness of measurement.
Just ignore it and move on.

Cheers

Alan

I see from your other posts on ASR that you are a football fan. Who are you supporting?

Oh man, we are out. USA, USA, USA 🇺🇸
I'm still going to enjoy the rest of it.

Which one is it @JasonWells ?
Au or Amsterdamned?

I attracted a ban a few weeks ago… I expected one on Audiogon, so I was a bit surprised it was on ASR.
It was mostly a misunderstanding on language, but it was a shock.

I see you guys down under are out too. You did well though. It's good to see the usually strong teams arent dominating. Makes it much more interesting.

Hi there Holmz

I'm visiting NY at the moment.

Hey have you seen they have locked the thread.
Jeez what total jerks.

I was thinking I might have been banned, so from my perspective a locked thread is a decent outcome.

Where are you when you are not visiting NY?

I guess you run a VPN?
I was temporarily banned a few weeks ago, and could not even view threads.
And I need to pull off some biquad settings, so I either need to be overly cautious or have a backup plan.

… an interesting request came from a member regarding the protection systems of our amps…

Does “our amps”, mean exclusively the March Audio amps?
Or…
Is it all the Purifi variations have it… as Purifi built in the protection?

I am assuming it is the later case… and that they know what to do so they implemented it wholesale across their range.

Yes it's all the purifi modules.

To expand further on the systems capabilities, it also monitors all the power supply rails, 6 in total. They all have to be within normal range or it shuts down. It also monitors for DC on the output and mutes the amp if seen. There is also a "fatal" line that asserts in the event of catastrophic failure, ie the output transistors going short. This line tells the power supply to instantly shut down.

So along with the current limiting, 25 amps for the 1et400 and 40 amps for the 1et7040, it's about as comprehensive as you can get.

Just clear your cookies if it happens.

Yes Aussies are out but we have our second team (well first to be honest) to support. We hail from England originally and emigrated to Oz about 12 years ago. We are dual citizens will be up at 3 am on Sunday morning watching England v France.

I think that's going to a stressful game to watch.
