Playing LP with the proper curve will make a big difference in the strength of the sound to anyone listening, especially the freshness of the mid-high range,

Since the sound quality of the LP differs depending on the label and recording , the SV-EQ1616D cannot only turn on / off the roll-off (high frequency level attenuation
characteristic) of 1 kHz or more, but also can make fine adjustments when the roll-off is ON. Since it is also possible to control the tone, you can enjoy each LP with the
optimum sound quality.

That is pure rubbish. Both Columbia and Blue Note had changed to RIAA long before these LPs were issued.

Whether it is a rubbish or not I do not know. I am not an LP expert. Everyone's cup of tea is different. just like you want whiskey. I want red wine. If you drink tea, you will add salt... it depends on one's taste. There is no right or wrong or rubbish. The most important is to make you feel better with the sound.

I translated the info from Sunvalley's Japanese website. This is purely Mr. Ohashi's suggestion to set the curve to listen to these LPs. (No doubt, I trust his taste.)

RIAA is the normal setting...

I forced my MM preamp to have the same frequency response as a cd with several albums and 45 rpm
Records. It is no longer dull with sloppy bass.

If you look at the bottom right-hand corner of the back of the Sonny Rollins LP you will see the phrase "Users of Wide Range equipment should adjust their controls for RIAA Curve".
Columbia stated explicitly in the booklet accompanying their LP introducing stereo sound that all Columbia stereo LPs conformed to the RIAA standard.
It's not a matter of taste.

 

[barretter]

I have an original of the Blue Note Art Blakey and it has the same statement as the Sonny Rollins I also attach Columbia's statement about their stereo LPs - both of the Miles Davis LPs are stereo.

[vkung]

No point to argue. RIAA is the standard. However, music is art so everyone’s ear construction is different. As long as the sounds makes you happy.

 

[barretter]

You don't address the question of the misinformation you are helping to spread.

 

[vkung]

As I said. The info from Mr. Ohashi from Sunvallery .
He is the expert in Japan.

There is no point to argue. This is a commercial section. You can agree or disagree.

 

[barretter]

What is that supposed to mean?

 

[vkung]

There is no point to argue. You can agree or disagree
whether it is a rubbish info or misinformation as you said.

I translated from Mr Ohashi's info.

You just wait few more days,, Stereophile review will be available to everyone....

 

[barretter]

I've already read the Stereophile review which is why I looked up this thread. I'm not arguing about the quality of the preamp only about the misinformation on the equalization of post 1955 Blue Note and Columbia (USA) LPs. Both these labels used RIAA equalization after 1955. Mr Ohashi is wrong.

 

[vkung]

I told you many times
You can agree or disagree the thread
Please google to see who is Mr Ohashi
We are talking from listening experience which setting has the best sound

We are talking different things

Thank you for your feedbacks
I hope we can stop from here

 

[barretter]

I told you many time that what you are saying about the equalization of post 1955 Columbia and Blue Note LPs is wrong and you have provided no evidence to disprove my assetion. I don't care who Mr Ohashi is : he is using incorrect equalization as a tone control.

 

[gpdavis2]

And, what if he is? If that sounds better as a result. then good for him. It is his ears/brain and his preamp has the curves to allow him to do so. You are beating a dead horse.

 

[barretter]

So presumably nothing matters so long as Mr Ogashi is happy? Accuracy and truth can go hang? I'm not surprised now that Americans vote for Trump.

 

[gpdavis2]

Wonder where you get this accuracy & truth crap? Mr. Ohashi accurately described which curves sounded best to him and truthfully reported same. You have Boris (but still talk and try to act like you have an empire) and we are, unfortunately, saddled with more years of trump (for which the entire world will suffer). Let it go. You've had your say.

 

[barretter]

In post no. 38 Mr Ohashi (via Mr Kung) says that the proper curve for the Miles Davis "Someday my prince will come" and "Kind of blue" LPs is Columbia/Old NAB and for the 2 Blue Notes is AES. This is untrue as both labels had changed to cutting with RIAA iin 1955. It is not stated as a matter of taste, but as a matter of fact. That is why I call it untruthful and inaccurate.
On the theme of "crap", I don't give a sh*t for your opinion.

 

[gpdavis2]

You are such a funny little man. And your statement of the obvious in your last sentence is redundant (very much like you).
