There are Class D power amps with linear power suppllies and there are Class A-B amps, like the Benchmark, with switching power supplies. My Class D uses a linear power supply. Yet, it seems that many out there associate Class D with switching power supplies. It all depends upon in what dimension of life one finds themselves living in.

GeneZ Posted January 21, 2019 Share Posted January 21, 2019 What if we found out that if we finally achieved the theoretically perfect home system? That the music and how it was recorded would not sound as good without some help from system coloration? And, that our home system could never be a recreation of the actual event? Our home system becomes its own event in its own right? That we need to make our own event by how we put together our home audio system? It can never sound like the actual event did. And, in theory, may end up sounding even better. I have witnessed to this myself by hearing playback of recordings of a live band I was in years ago. The recording (in my opinion) made us sound better to listen to than being there. So... we must discover what combinations of colorations suits us just fine. And, leave all the opinions of others walking down a path having no end. Find what you need to enjoy and have your own home system be truly our own. Not a slave to trying to please the opinions of others who constantly wander seeking today's ideal that is not really the answer needed. For, when does distortion become a none issue?

Anyone who has been in audiophiledom more than a day already understands that measurements such as THD are correlated with good sound quality, but are not the exact measurement of SQ, that a bit of 2nd and 3rd order distortion (but not too much) is liked by many (most?) and is why tubes have stuck around, etc. etc. The video is just more of the same. The real point of the video is to sell Dan's "world renown" art in coming up with just the right amount of "mystery" (his word) distortion so that the sound is "musical". Same old same old.

This "coloring" is known (if not well understood) and part of the Audiophile world. Its relationship to fidelity is controversial. GeneZ point is the common art and wine radical subjectivism with the strawmen "how does it sound", etc. and is the usual trope. On topic, THD and the like are relevant, correlated to the sound, etc. It's not the end of the story, but it is part of it... Do you know how you sound? How your response resonates?

The problem is that someone inevitably does not like measurements and how they question a purely art and wine evaluation (such as GeneZ). I like measurements..... within reason.

When it becomes a controlled and standardized industry the listeners will tend to become jaded and the thrill fades . Creativity when its best is spontaneous and joyful ... not matter, even if its the blues.. When everything gets controlled and standardized a type of "smiley face" sadness takes over.

If love is measurable, there no reason it can't be measured by some one not in love. What science can only measure is sexual arousal and euphoria... by hormones present in the body. But, that's not love. That is why amplifier measurements are not enough to know which amp will sound the best. Though measurements will be valid in showing which amps will sound bad.

Those with an 'objectivist' bent are obsessed with the concept that conventional measurements are good enough to tell the whole story. Because, the Important People have said so ... meantime, in the real world, lots of people have found this is hokum, by using various approaches to push the SOTA. The objectivists jump up and down in rage, insisting that people are using distortion to sweeten the sound - ummm, red herring, anyone? A big problem is inertia - the audio business has fallen into a major pothole in its thinking, and only some are trying to get out, let alone even realise that they're trapped in this attitude dead-end. The best sounding systems in my life were some of the worst sounding by today's standard. What we see often times today in reviews is like telling a depressed person to have happy thoughts and the depression will go away. A great sounding audio system is 90% how one feels to begin with. One of the symptoms of depression is the inability to enjoy normal things. Can what is considered a great audio system make a depressed person to not be depressed? Or, simply be distracted for a moment in time? If someone could make me feel 14 again? I would have absolutely loved many of the systems I have owned. If it can be done for age 12? Other styles of music would have been fully enjoyable. There is a mystery at work when it comes to music enjoyment. Its got to do with how we feel inside to begin with. The music only finds a welcoming opening to fill. If that opening is not there? It can be a 100,000 system, and be "meh." crenca, esldude and Teresa 1 2 It all depends upon in what dimension of life one finds themselves living in. For, one man's music is another man's noise.

The madness ensued on AC. Now I currently use the Hypex NC502MP as shown below. I have yet to hear a Hypex Class D amplifier. I have heard an ICE amplifier (PS Audio S300) and its very good sounding. I prefer my NuPrime ST-10. If I never heard the ST-10? I believe I could be very happy with the S300. Audience manufactures excellent speakers and cables, was looking at Hypex N core for their own amplifier. As far as I know? Its not being manufactured as of yet.

Yes.. Loudness control is essential for low level listening. I have gotten in trouble a few times when I mentioned it. For my loudness control I chose to use a Barcus Berry BBE Sonic Maximizer.

GeneZ Posted February 6, 2019 Share Posted February 6, 2019 There are amps that designers add in even harmonics to produce a very nice "tube" effect on the sound. I have heard it. It even sounds better than what I heard heard with tubes. In essence, its the best of both worlds. Because they do this? The better sounding amp will not show as low distortion measurements.

I just noticed that the Resolution Series 255-MKII uses the same type of potentiometer as found in my passive preamp. https://image.jimcdn.com/app/cms/image/transf/none/path/sb99076bb5e16690c/image/ie536af55798bec26/version/1391575986/meticulous-attention-and-precision-in-every-detail-is-one-reason-for-unique-results.jpg I gain the second harmonics with my NuPrime ST-10. Very tube like in a very satisfying way, especially when its obviously sweet and detailed. I also have a good tube preamp that sounds surprisingly almost identical with my passive. Both use the same potentiometer. Very neutral tube preamp at that. My passive preamp (when used in balanced mode) is the audiophile secret of the century. I use only top notch balanced cables and sit back and laugh! One balanced cable alone costs more than this unit! Nob sound passive preamp The NobSound will make your high-end system sound as good as the components you choose to implement. maybe I got an unusual piece? Its so simple in its implementation. Hefty metal casing. I am now learning how power cords can greatly effect what is heard. I may even place my tube preamp for sale in the near future and concentrate on finding the right power cords. But, first. I am going to test to see how different power cords will effect this nice triode preamp. It all depends upon in what dimension of life one finds themselves living in.

I'd hope and expect that a tube switching amp designed by a mind like Hegeman's would sound great. That may be something to keep an eye out for. I wonder what the problems may be in implementing it and bringing it to the market, other than the notion that tubes are not as readily available as they once were, and need to be replaced. How could such speed be maintained and know when its time to replace a tube? (typical question that will be asked) When I was in the Army Signal Corps we were trained on tube radios...
