You need to learn basics like; Vx2=+6 dB or Wx2=+3 dB. This tells you how if you want louder you better get more sensitive SPL/W speakers than power amplifier with little more output. For example a 84 dB SPL/W driver will need 4x more power to get to 90 dB that one with 90 dB sensitivity.
Thank you for your good opinion.
It is good to use high SPL speakers, but the problem is that there are quite a few brands with lower SPL than I thought. So since I can't choose the SPL, I'm looking for an amplifier with high output. Anyway, if the output is high, I can reproduce the appropriate sound even if the speaker SPL is low.
As you said, I will try to learn endlessly. I like learning! I will study hard.
You have the cart before the horse, as it were. I certainly would not want to be the person who got you to buy a $10000+, kilowatt per channel amp, when you then choose a speaker that runs happily on a tenth of that power or less. Do things the right way round and you will be happier, faster.
Thank you for your very appropriate advice. I also understand what you are trying to say.
The reason I have a clear goal and am looking for an amplifier is because my goal is to use large floor speakers with 3-way or more. I want to use speakers that are taller than me, but it is not easy in terms of money or space. However, I have a goal. That is why I am looking for speakers.
As you expected, I live in a country with a fairly wealthy GDP. Of course, I do not have a lot of money. It is just that many people around me use good systems, and I have good relationships with various audio brand importers, so I was able to listen to various products in their demo rooms.
You can think of all the major brands that you can think of as my choice. There are almost no brands that I do not consider.
However, since I started considering Class D amplifiers thanks to your recommendations, I have more money. So I am more greedy about speakers.
I want to try various high-end brands of speakers, so I am waiting for a used product at a good price.
I will choose slowly. Thank you.
Of course it is. You can either shell out a ridiculous amount for it, audiophile style, or track down a used Yamaha Pro power amplifier since they are all Class D today.
Easy..
Yes. Considering the Class D amp, it's a very reasonable price with good specs and performance, and I'm very happy that I have some money to spare.
Just the time gap making those changes nullify your results, tho. How did you measure noise and dynamic range by ear? Let alone "sound qualities like harmonic balance" whatever that is supposed to mean? Like I said, you have a lot of mis-conceptions.
ps let alone level matching or blind....(and quick switching obviously not even possible)
Right. I can't say that I made a proper judgment in that short time. I might have misheard because of my fixed idea or placebo effect.
But what I hear is the most important to me. Of course the specs are important. Of course the measurement values are important too. These two factors can be the criteria for choosing a good product.
No matter how good others say it is, if I'm not satisfied, it's useless. So I have to listen to it and try to choose a product that I'm satisfied with.
Of course, I understand your thoughts that such tests are meaningless. However, most people who buy very expensive hi-fi products pay their money through such meaningless acts. No one buys a product without listening to the sound or comparing it.
Even if it's B&W or McIntosh, they buy it after listening to it.
And one thing I want to say is that if you listen to music with the most expensive products of all the super-expensive brands, such as the new Wilson Audio WAMM, the sound difference is significant even if you change just one interconnect cable. In other words, because the change is big, it's easier to compare. Then, can you say that comparing the differences between preamps in this system is completely meaningless? No, there is a difference.
No matter how much people are mistaken, delusional, and fixed-minded, if there is a difference, they should be able to feel it, and for those who can't feel it, an expensive system is meaningless.
I was lucky enough to listen to the new WAMM system for over a year. I even did the settings myself. The owner of the system asked me to re-set the sound because the amplifier had changed. So I did everything myself, including the speaker positions and module settings.
Since I had to do the settings without EQ, I went there often and set it up for several days.
The sound of a system made up of only the top 1-2 most expensive products from each brand is really on a different level. You have to hear it to express it.
Money isn't everything, but if you build a system with products that have both performance and brand value at a very high price, it will sound fantastic.
Anyway, my listening standards are the most important to me. This will remain the same in the future. If I don't have my own standards, I have to choose based on other people's standards, and if that's the case, I wouldn't have any reason to have this hobby.
