Could Class D really be that good?

The only way to know if a single component (or several) changes the sound and or measurement is to use the same amp and just change the parts.  Then you will actually KNOW something.

This statement contradicts this one:

I did not say it changed the measurements....

I have found over the years that when someone is willing to contradict themselves in an argument, its never about the truth of the matter; its only about trying to make the other person wrong.

This makes a noticeable sonic improvement......and no, I bet you cannot measure it. 

(emphasis added)

Despite the obvious syntax error, the above statement suggests that no attempt was made to measure any of the changes introduced. The reason you would want to do measurements after changing anything in a class D circuit is noise and parasitics can show up, which can interfere with other equipment, for example an FM tuner or digital equipment sitting nearby. Bruno, the designer of the Purifi and Hypex modules, is very emphatic about this in his papers.

@lanx0003 BTW, if anyone tells you they have 6N (6 Nines, IOW 99.9999% copper) copper wire, if you are in their presence it might be sensible to turn and run as hard as you can. 6Ns copper is a myth; it does not exist. Wire manufacturers just laugh if you suggest this sort of thing to them. What is real is OFC (Oxygen Free Copper), which was not developed for audiophile applications (see the link).

It's funny how you can find cables labeled as 6N, or even 7N/8N OCC or OFC all over Amazon and AliExpress, and they're incredibly cheap. It's amazing to see the quality control and production efficiency of the plants in China these days???  I am a bit being sarcastic.

Ralph,

It took you two days to reply and that is all you can come up with? You will say anything just to make me look bad so you can feel you are right.....wow! The two statements are not contradictory......I said "if it changes the measuremets". Again, never implied it did. You are just making something up to make me look bad, so that people might dismiss the fact that you stated something untrue. You are lying.....plain and simple. You cannot measure the distortion in high end used passive components......that is a lie.....and you know it. You have never proved that you can....and no other designer (that I know of) has ever said this except you.

The only way you can prove you are correct is to show measurements. The only intelligent (non ego driven) response to this post would be that:.....your measurements....your quotes from others who have tried this and show their measurements. Any other reply would just be from your ego.....(defending your postiion...without proof). So is the statement you made true? If so, prove it. Othewise it is a lie.

Why would someone make up stuff and post it online? I try to state what I know about....that is directly experienced or relay info from others who directly experience stuff.

I wish you well, but stating something on a public forum that is not true and then defending the statement by trying to make someone look bad who points out your untruth (rather that prove your original statement).....does not help your reputation. Why would I trust anything else you say if you just make up stuff and post it?

Now you are saying 6N copper is a myth. Can you prove it? Is this a belief or a BE LIVE? Please show us the measurements. From what I read, the claims of 7N and 8N are made up, but 6N can be real.  All wire sounds different no matter what the amount of claimed Oxygen free level. A single piece of wire will sound different depending on the direction it is used.....even PCOCC wire. All above sonic statements tested with my ears....so it’s a BE LIVE. Belden make the Iconoclast insterconnect cables and those guys are VERY scientific.....however, they make three different versions....pitch copper, OFC and PCOCC. They go up in price accordingly. Every one who has reviewed them agrees that the PCOCC ones sound the most transparent. Everything makes a difference....my usual statement. And Everything is LOVE.....the statement of the Universe....every second. Enjoy.

A simple upgrade is to order the Fosi with the 48 volt power brick. Go to ASR to read the recent test report.

I did try the 48-volt PSU, but the truth is, it doesn't deliver better sound than the 32-volt PSU at normal listening levels or even at 80-85 dB. Surprisingly, the 32-volt PSU offers cleaner sound, leading me to believe that it is the better and less noisy SMPS option. Moreover, in terms of power requirements, the 32-volt PSU proves to be more than sufficient for a small to medium-sized room.  The 48 volt psu also drives the amp unit noticeably warmer than the 32 volt which will potentially shorten the left span of the amplifier.  Not recommended.

I am with ricevs. As I do with many pieces and doing it for over 50 years, I finally got around to chassis damping my LSA GAN 350, including changing out the stock rubber feet. What I hear now vs stock, are cleaner, faster and more agile sounding transients, more air around the instruments, greater articulation with the "playing" of the instruments, and greater dynamic contrasts. The rear panel alone was very "alive and ringy", and now it is dead silent. The power cord, interconnect cables and speaker cables all have a quieter environment to contend with. Everything makes a difference in what I hear. Could care less if it is measurable. GANFETS, to my ears and in my system, are the most enjoyable class D I have heard, and in the last 18 months, I have heard many. My best, MrD.
