Could Class D really be that good?

Boy you just keep sawing on that limb.......you cannot say anything but the same thing over and over and you know you are wrong and cannot prove otherwise. You alone hold your opinion. I have been around since 1975 and in the industry since then. I did not say it changed the measurements.....but if you are going to look for a different measurement than that is the way you would do it......using one amp or device.

Please prove you are correct. Show us the measurements......You know you cannot or you would have done so by now. You know you are wrong and just keep saying you are right. Would you rather be LOVING or RIGHT. Some would rather be dead right then ever admit that they were wrong. Are you one of them?

You are not your thoughts....you are not your opinion. You are infinite love and joy....and always will be....forever and ever. You can let go of your opinions because next life you won’t even remember them....you will obsessed with something else you need to let go of....he he.

When you really truly love yourself at your core.....you cannot do or say anything that is not in harmony with your soul.....you speak truth. Please love yourself more. I would love you to be more happy. Having pretend opinions...to be right...is not happy creating. Growing up and admitting you are wrong is the hardest thing to do. We are all so stubborn (me too). It is so easy to be bad......to be righteous......it is hard to be loving. It takes great courage to be loving. For we fear rejection....as we reject ourselves. Look in the mirror when you first get up in the morning and smile at yourself and tell yourself out loud that you love yourself and are beautiful. Do this several times every day.....Caress your face like your mother did when you were a baby. I do it when I drive. Wave at people. Tell people how beautiful they are and thank them for sharing their light with the world. Treat yourself and everyone as if they/you are your pet or baby. This is the way to really start to feel love for yourself. There is just God loving itself. You are your mother....the mother of all.....loving your self and everyone. Forever. This is the truth of your soul. Bless everyone.....forever.

Alright, it is fun discussion but counter-productive (to me) talking these technical issues phyosophically.  Call me stuborn but, before making any major purchase / investment, I would like to see positive / superior objective measurements on the particular model I intend to purchase to get the maximal bang for the buck.  I will also do my due diligence to get the users' and revierers' (I thrust) feedback and get a feel how it sounds.  I won't make my decision just based on diyers claiming that all Purifi / Hypex based modules (including power supply) measured the same.  Different implementation in the input buffer makes significant difference!  And that is true!

I don't think you are subborn.  You are just checking out all possibilities.  However, ASR themselves say that super low distortion is not required for "perfect sound"  Only a certain measurement of SINAD is needed.  They like lower measurments but they never claim they sound better....because they believe everything that measures below their SINAD value is perfectly transparent.

It is not just the input stage that changes the sound in a Pufifi amp build.....it is the damping of parts and the input board.....the cables, the AC inlet, the output connectors, the quality of parts on the input board. etc. to infinity.  I modify the Sparko regulators and the Sparko pro op amps for better sound.  I modifiy the ouput filter caps on the Purifi boards by removing all 6 on each board and removing the distortion producing steel leads and soldering 6N copper leads using Wonder Solder.  I then test the caps for outside foil and put them all back in so the outside foil is to ground on all the caps.  This makes a noticeable sonic improvement......and no, I bet you cannot measure it.  Look at the reviews of the NAD Purifi amp and my modded Purifi amp on 10 Audio.......he says my amp is way better and even with the mods it is cheaper than the NAD.  This game is infinite......just like our own nature. Eveything makes a difference and most things that make a sonic improvement cannot be measured.

Ric,

I really admire what you do and wish I could learn that skill set someday. It's a pretty good review, and I congratulate you on the impressive 9.5 out of 10 score you received for your mod. I agree that measurements do not imply sound quality, and I believe the listening part of the assessment is greatly lacking in the ASR review. Nevertheless, it is suggested that you send your mods to ASR for his complimentary measurements. Coupling with the excellent listening review you have received, a potential outcome from getting more comprehensive measurements done is that the forum will get to know your mods, your sales will be boosted, and the community will benefit from it. A win-win situation.

@eddnog  I didn’t see any results from anywhere testing the V3 Mono specifically with a 5A power supply versus a 10A, making it even more difficult to say.

Erin just shows the test result today. 'Single' means single amp fed by 48v, 5A psu and 'Double' means double amps fed by 48v, 10A psu.  Having individual 48v, 5A psu feeding to the v3 mono does have 10dB advantage in THD. Interesting.
