Atma-Sphere Class D… Amazing

Unfortunately they are a bit too expensive for me, will there be a cheaper stereo version ?

Great posts @atmasphere

You answered all of these questions with precision and grace. In addition, we all learned a great deal. As an avid DIYer and modifier I know many pieces of gear can benefit sonically from parts upgrades and such. However, Ralph has articulately stated why some of these mods will not yield positive results in his design. I both believe him and trust his knowledge.

Unfortunately they are a bit too expensive for me, will there be a cheaper stereo version ?

I sure hope so! I want maybe 50W/Channel stereo integrated.

While I agree with many of your points, consider that ALL aftermarket improvements to engines/suspensions...

There are improvements, then there are modifications to suit the end user. Improvements can be proven to actually improve the performance in an objective way- more horsepower, faster lap times, etc. The kinds of modifications the tweak guru always proposes do not improve the performance, most actually degrade it. They do modify the sound, which some may subjectively enjoy, but others may not. Therefore, we can't call them improvements, and since there is no way to objectively prove they improve performance, they are simple modifications that some may like and others may not. Think of racing stripes on your car, or mag wheels, not turbochargers or ground effects.

My goal is to inform people so they can improve their stereo or their lives....that is what I do. The mods I suggested are completely universal. If you did this to a $400 Topping or a $120,000 Gryphon amp the results would be the same....except you would hear more difference with the more transparent piece of gear. When Mytek FINALLY releases their ($20,000) 500 watt a channel mono block GaN amps (now supposedly shipping this month) and a thread is posted here on them and a pic is shown that shows bolts and plates on their tranny then ......I would IMMEDIATELY suggest those with the amps remove that hardware. THESE MODS ARE UNIVERSAL........and the ONLY WAY you would know this is to have tried these things over and over again and had feedback from people who did these things. I have had the information about the steel plates, etc. on my website for OVER 15 YEARS! Every person who has tried it (that I know of) has found the sound improved....(on their amps that I have NEVER seen or touched).

Gryphon amps, Audio Research amps, etc. etc. have fuses that can be upgraded (and thousands of people have upgraded their fuses)......better fuses sound better in ALL equipment. Better jacks sound better in ALL equipment.....better op amps sound better in All equipment.....better wire, better footers.....on and on into infinity...this is just how it is. The game is very complex.....and most manufacturers are not super tweaky explorers.....they have an opinion as to what they think is right and implement to their predilections. This is how the ego works....it defines and defends....D’Agostino makes these monster Relentless amps and they made custom output connectors for them.....big hulking things....made from pure Brass.....Brass? A high mass brass connector? Sorry, this is horrible....How about copper, how about OFC copper, how about cryoing, how about PCOCC copper? No, let’s make them from distorted sounding brass. Have you ever listened to brass speaker cables? You would not want to. .If they used a low mass copper nextgen from WBT they would have much better sound. I actually sent an email to D’Agostino and even showed them by binding post bypass system. Are they going to change what they do because I told them that.............NAH........define and defend. Limitations are what the ego lives for. The soul lives to expand. It wants to know more and feel more and be of more service to more people.

Some manufacturers, over the years have implemented my ideas and copied my products.....I invented the shunt attenuator back in 1989 and it was copied by several manufactures......etc. We ALL make a difference.

If you want to believe these mods are only for Pintos and not Corvettes....well, that is your belief......but it is not based on facts.....only those that try something...know what something does sonically. Any one of you who owns these amps or ANY amp or any DAC, preamp, etc. that has a steel cover and bolt that can be removed can try this mod and see for yourself if it really works or not. Any of you who has a product that uses fuses...can try an audiophile fuse......Changing op amps, jacks, eliminating jacks and the like need to be done by someone who knows what they are doing about this stuff or is a DIY person. But ANYONE can change a fuse or eliminate some steel hardware....or use better footers or add damped weight on top....or lift their cables off the floor. Lots of things the "normal" audiophile can do to improve the sound. Since most things that improve the sound cannot be measured.......then the person who does the change is the final decider of whether its an improvement or not. When you have almost everyone agreeing on a change having a benifit.....to me that is objective truth.....based on listening. This is what we have to go by.....not measurements. When we finally come up with a machine that measures the sound differences in wires, jacks, op amps, resistors, inductors, etc, into infinity....that will be nice....Until then....we have our ears.....Please, trust what you hear......trust what you feel.....love one another. Have fun....
