Lots of solutions to make it work as an amplifier... this way and that way.

Thank goodness for a positive response, fas42. I believe that just about anything makes a difference. I have found, in my experience, that overlooking something that might not change the 'specs' can sometimes destroy the product in the marketplace, EVEN IF the public or reviewers don't know anything about the product, internally.
This is what I have been trying to put forth on this thread, for years, you know the 'subtle stuff'.

Robert F,
I am just giving you a hard time...... I get along just fine with Qusp. Actually I was just saying if I could just take off and move somewhere else today if would probably be to your neighbor New Zealand. That is since I can't afford to live in Hawaii. But we have had this argument not very long ago. Some of the things talked about are just beyond what some of would deal with in equipment.
Christophe,
I think that some must think that you mixed your primary mix on some of these horrible self powered monitors that are out there. I won't say that they are all terrible but most of them are just fair at best. The acoustics of a recording studio on the recording side is something that was taken seriously before the advent of all the home studios. Live recording is probably the hardest thing to do, but multi-track recording in a studio is another story. When someone spends upwards of a million dollars for a mixing console and all the outboard equipment do you really believe that they don't care about any noises that could possibly be removed? I believe you Christophe that you wanted to do the best job that you could do and wouldn't accept a noisy path cable or a linear slider making noise as you changed a level. Frank I would be the last one to argue that there are not some atrocious recordings. You told me that it was just my equipment but sometimes it is just obvious something isn't right. I can listen on a horn loaded system in one room and a direct radiator system in another. I may not understand all of the electrical circuit design going on here, but I do know the speaker side of things. I have been around PA enough to know that it comes down to the mixing engineer whether I can listen to the system or not many times. One person will just make a vocal sound terrible and the next person walks up, changes the eq slightly and there is such a difference you would think the system just changed! Last time I had my hearing checked I complained to the people about all the noise leakage into the booth. They told me not to tell my wife that my hearing was still nearly perfect, otherwise she would have known I just wasn't listening to what she said.

Fragile because lots of it looks like a prototype and it's not physically "stable" - if the cat brushes against it I've got problems! It's also nothing more than ordinary components, quite old parts, a heavily modified, lowly HT all-in-on; and the average quality, and age, means that it has to be thoroughly warmed up first.
But I'm not interested in solving these "ordinary" problems, rather the issues that still beset most audio; and my current setup is good enough to let me hear when I make progress there. Remember, I just went to a high end audio show, and nearly all that expensive gear still displayed the same problems I've been working on.
Most issues are under control, I still have trouble shielding from interference. And, I'm doing this at a hobbyist level at the moment, I haven't the access to the sort of gear that will give better, faster answers ...

Frank,
I can buy that, so really it is on your side that you are having problems. But if your system is of the level you speak of how can you say you can determine all these problems as anything but in your own personal system? I have also heard much of the so called high end systems at the CES and also the Stereophile shows. What passes for super systems are often not, I walk out of many rooms shaking my head wondering what they are thinking. It always amazed me when the system was playing barely above the background noise level of all the people walking and talking. How were you to evaluate a speaker when it is running at such a low level? I did get lots of grief at the CES show one year as the bass from my room was heard down the hall and especially in rooms under me. What was I to do in a hotel room making 35hz on the bottom end?

Specifically in regard to supplying voltage rails to a circuit with poor intrinsic PSRR, that has other admirable properties so you proceed in using that topology. Even if there is very high current draw there are ways of making the rails exceedingly stiff, at all frequencies that count, at the points in the circuit where it matters. All already out there, and there are smart ways of doing it, that don't need to be super expensive.

Because I've listened to numerous systems, at showrooms, shows and people's homes. Like all people I'm listening for certain qualities, that are important to me, and key amongst them is the ability to sound "natural", obviously a huge can of worms as a description, and to be able to retain that quality irrespective of volume. And there are very, very few setups that I've heard that do that.
So what do I mean by "natural"? Generally I rely on "difficult" recordings, as instant giveaways of the abilities of a system to portray a realistic sound picture. At this point I'm reminded of a particular room at this show, which seemed to be doing a nice job; until, he put on "Frankie Goes to Hollywood" - terrible!! Didn't have a hope of getting anywhere near being acceptable ...
And as a breed, New Wave is as good a test track as any: the mix, reverb, everything conspires to knock over conventional hifi. This should be able to run at deafening levels, without the slightest harshness or oppressiveness, and you should be able hear deep, deep into the mix, every detail as clear as clear can be ...

Brad, you are not a nice person. Please give Christophe his leg back.
OK, you guys can go back to storytelling now.

It is not that, Robert.
I began my professional life, long time ago, as a R& D engineer in an audio manufacturer. We had a vibrating machine strong enough to break internal printed boards and eject capacitances.
We used-it to test our new models resistance, at the limit, measuring the output, and even distortions under vibrations. And you know how a distortiometer is sensible to the littlest defect ?: Nothing, nada, rien.
I am curious and try to explore the things in a scientific way. When this story about magic cones arived in the audiophile magazines, i tried-it cones in my system: no change. Under my enclosures, changes, but that is easy to explain.
About monitors in big studios, they could be colored (not flat), like Tannoy or Urei, so you could make mistakes in your balances and equalisation that we could discover later outside, but they are always able to produce VERY high levels at low distortion on all the bandwidth, from very low frequencies to the highest. Very dynamic (horns) an ultra defined and a lot of presence (sometimes too much with a lot of listening fatigue).
Anyway, to ensure no mistakes, and good balances for both hifi and radio, we verify our mixs on little speakers (often two different) and personal headphones: one of mine was a Stax. of course, we made personal copies to listen in our homes, with our well know system for the same reason. And they are verified (with sometimes equalization and dynamic reduction) during mastering by the specialist on his own absolutely different system, then by several persons in the record company listening rooms etc. Big money involved, we played our lifes on this.
What's the problem ? SAid something wrong on a technical point of view ? I'm too talkative those last time ? If it is that, you're probably right. i will take care.

Your getting a crash course in colloquial English, without the textbook and a in classroom of clowns. Your are doing quite well given the challenges. I can barely keep up and its my native tongue.

The clown, it's me, or more exactly a 10 years old baby. That's the way i feel when i write in English. But it is nothing: you have not
heard my accent, otherwise it would be a chorus of seagulls.
I never miss any irony in my native language, and love-it, most of the time perched on the second degree.
Don't ask-me this in English, i have not yet reached the first.
Thank-you for the lesson, and Brad for allowing me to understand this nice Jefferson old song for the first time. (Well, i'm not so sure to have understood everything in it, neither
No not at all, just a flippant and random reference. Not sure what Sy was alluding to.
And I would dearly love to be fluent in French ---- although I might now be married with children had I studied it in junior high.
You mean American girls require love's declarations in French ?
That's explain why i was so tired, each time i was in L.A !
Now the things are a little more complicated for young french guys: They use to say "J'te kiffe trop grave" instead of "I love-you" and nobody understand.
Right, they power-up GSM satellites that way.
