I miss my Loudness Button and Tone Controls....

’Loudness’ is for any system, any speakers, in any space.

fundamental to maintaining involvement at low volumes, i.e. bass player in a Jazz group. sparkle of triangles ... It should be progressively engaged as volume lowers.

Good description...

LOUDNESS is very well done circuit with the Sansui AU 7700...

I forget to use it because my room is so acoustically good that even at near listening (3 feet) i forget to use it BUT i just test it now, typing these words and i have 2 choices? : boosting only bass or boosting bass and the highs...At very low volume it is very interesting to use them....

I dont need it and i forget about them because even if i listen at lower volume i dont feel i need it.... But It is impossible to contest his usefulness in normal non controlled room...

Contrary to a well know opinion even at near listening passive material treatment and acoustic mechanical control of the room make a huge difference on sound quality and perception....it is one of the general opinion that is trusted but is FALSE, when listening at three feet of the speakers like me half of the time, the difference in near listening was HUGEif i compared  before and after room control especially and room treatment...But even there i will reminf myself like noiw that at very low level it is a useful feature this loudness button indeed...

If you needs a loudness button or tone controle or equalizer throw your set at ebay.

Too harsh opinion or too uncompromising one are take us often is simplification and misunderstood...

loudness button is not a feature on under par lower designed product generally, especially in the golden age of audio where designer expanse without calculating so micvh on quality parts in their war to take the market.... I know that Sansui is generally well designed...

loudness button may be very useful for people who are in the obligation to listen very low because of their partner or by their own choice....

Nothing against equalizers with digital. But my vinyl gets as clean a path as I can make. The amps are simply a mechanism to amplify, RIAA notwithstanding, and drive the speakers. If all is on order, you shouldn’t even be thinking of modifying the sound with additional stuff. Transparency is key to the best sound retrieval. Additional modifying circuits impact that micro-detail transparency.

I love having a loudness switch and tone control as well. But if it just the loudness switch that need to add to your system then I would recommend looking for Micro Ifi Tube buffer II which has a Xbass loudness switch that you can adjust from 0 to 6dB and 12dB and there's a 3D Holographic enhancer for your speakers. You can also adjust the tube buffer from 0 to 9dB as well.  This Ifi Tube buffer work well for me and you can research on Ifi's website before making your decision.

"Theological" audiophile dogma which are false or off the mark when taking by itself alone:

-

-An amplifier with tone control or loudness control cannot be a high end product or be a qualitatively very good design..

--You dont need room control or treatment if you are in near listening position ( the speed of sound contradict this because the waves cross my room 13 times during one second and my brain/ears use the reflected waves and not only the direct waves in the fraction of second they need to CREATE sound impression)

-- Cables dont make a difference even a small one...( they did in general but a small one )

-- Acoustic treatment is enough, acoustic mechanical control, will add nothing more ( sorry but Helmholtz will not accept this one)

-- Ionization devices and Schumann generators are snake oil even at low cost ( I experimented with them sorry and they are very evident reason why some people dont perceive their action at all)

-- Speakers cannot own the same intimacy impression quality than headphones ( sorry but it is false if we can use well acoustical simple facts)

-- ALL "tweaks" are useless ( so wrong i will not comment)

-- we can measure everything....(It is false because the ears brain only mesure everything that matter for us in sound perception not the other very specialized tools by themselves alone and it is even trivial and common place to say so )

-- all that matter is our subjective impression ( that is no more false than the last dogma above saying that we can measure everything that matter)

--Unlike the RCA dog logo we listen to the system/room not to the system only...

The most important audio fact for our journey perhaps is how to learn to CORRELATE precisely measured and located phenomena and devices with our own subjective perceiving apparatus IN OUR ROOM...

There is many others false dogmas help me to find them... 😁😊

The sansui au7700 is a amp 1975 i had the au417 that was mine first amp. That was 1977 with AR speakers and a dual turntable. I never used the loudness button.

Sorry but if you like loudness you dont know how to listen. The same is with magnepan why people put a subwoofer behind it is so wrong. The problem is not the maggies but the amps. And the low from the Maggie is so naturel but people wants a boom box. So that's why i hate loudness also.
