What I mean is that the RIAA curve in the equalizing amplifier must exactly match the RIAA curve of the record on the record. There are actually very few amplifiers where you can accurately select the required RIAA curve.

It takes a special kind of blind arrogance to lecture John Curl about amplifiers and "the required RIAA curve". Congratulations, you have clawed your way into the top 10% of poseurs, ponces, and pretenders. Perhaps you can succeed in breaking into the top five.

Billshurv & Bonsai,
Though Indian Classical compositions by instruments are well liked, I know most western people avoid Indian Classical Vocal. A rather crude similarity one can compare it to Opera singing. Pt. Jasraj is one of the legendary classical singers. Dedicating 50/60 years to only Indian Classical.
Jazz in India.
It was in mid 1900s to counter Russian cultural influence American Govt. Decided give exposure of Western Jazz etc. music to other parts. Dave Brubeck, Louise Armstrong, Miles Davis probably John Coltrane all visited/performed here in mid 1940/50s. More or less these greats were interested in construction of Indian classical music. But I think (not sure) only Miles Davis and Coltrane did some indian inspired composition. Alice Coltrane was very much influenced.
We also had jazz musicians. "Jazz Yatra" (Jazz Journey) was annual jazz event here. Which Sadly ended in early 2000. Our Biggest Music Shop in Mumbai closed too recently. So legends passing away, music events not taking place musicwise things are not good. But I here few years back Western Classical Music event ran full house in Mumbai. You can read Improvisation and Indian Classical in this very old thread by some one who can speak authoratively Mr. Asit. Here.
Here are interesting stories about Jazz In India. Lots of Articles, links and unknown stuff. 🙂

I understand you GUNFU, but being a slave to accurate frequency response is not what I am into for the most part. I like an ACCURATE RIAA, and I leave everything else to chance. I agree that certain Eastern European countries might deviate, but I don't have any examples in my record collection.
In my experiece with John he does make a serious effort to get the electronics right. Certainly to the best the available equipment will show for response and distortion.
Unfortunately there are loads of significant response errors upstream that are not controlled. Assuming the tape is working well its probably within 1/2 dB from 50 Hz to 15 KHz, maybe. But the cutter head is no better if even that good. And then the cartridge is a real wild card. Response difference may be a significant contributor to the difference in sound from different cartridges. So what is right?
Contrast with digital which if executed competently will have vanishingly small errors of response, dynamic linearity and distortion. Real question- is accuracy the right goal?

What's wrong with checking your phono front-end FR with a test record, at least to see where you stand, if not to make actual corrections? Wasn't there a CBS LP with freq sweeps?
Of course that doesn't fix anything that happened upstream, but would certainly shed light on your cartridge/preamp match (or lack of), which as mentioned can be a significant variable. I've always been a little surprised that this sort of test isn't discussed much in the phono world. Or is playing around with the different "sounds" of various FR curves just part of the vinyl "mystique"?

Your post has just prompted me to try an old test 'squeak' record to see what the FR is now.
I haven't used it for 45 years, and have a different deck, a new pre-amp and cartridge, and a PPM, which was what I used at the BBC to align record decks in routine maintenance.

Obviously, in your wounded arrogance, it is you who are offended, not Mr. John.

Demian, I think +-3 dB (so 6 dB span) on the average LP played through any system is about what it is generally.
As long as it doesn’t screech in the 2-4 k region and the bass is smooth and not lumpy, you’re good to go IMV. That said, I still try to get the RIAA accurate - at least it’s the one thing you can remove as a major error source from the signal chain.
Ahh, the joys of vinyl.

How long before cables made from these:
‘Electric mud’ teems with new, mysterious bacteria | Science | AAAS
start competing for space in high end cables?
The new snake oil?

Hi,
the difference here is that bacteria were joining their cells to make 5cm long conductors within the mud

If it were not for my wife I would certainly have not developed a liking for it. Rajasthani folk music is proving a harder nut for me to crack!
Another option is traditional music but on guitar one of my favorites. Pt. Brij Bhushan Kabra, the genius of Indian Classical Guitar, presenting Raga Puria Dhanashri. - YouTube
Yes I had this on vinyl. There were few more artists who used western instruments for Indian Music. Unfortunately I forgot. There were lots of Disco and Indian Classical fusion too. Which I dont like but it became hugely popular in clubs in the west so go for inexcusable prices.
For me too. Being diverse country we have lots of music. Folk music I rarely listen probably on rare occasion 'Gujrati' which is my native language. and very often 'Marathi', regional state in which I was born.
East and west fusion music is also difficult for me. But I do like 'Coversations' audio CD. (Subramaniam & Stephan Grappelli) which I like. Also have couple of British Indo Jazz vinyls which I rarely listen but have kept it. (1) Curried Jazz. kept it because it was recorded in UK and to study the structure which Victor Hugo arranged on research (2) Indo Jazz Fusion (Joe Harriot+John Mayer) also for good recording.

Thanks for the link, I'm enjoying it while fixing one of my Sound Technology 1500's...bad fan.
Cheers,
Howie
edit: I forget between uses how damn loud the fans were in these things!
A friend was recently retired from teaching college. They told him to clear out all of his stuff by Friday. So I sent two of my guys with a truck.
They brought back 2 solid state Ampex 350 tape decks, a Scully full track and a 4 track. Of more interest is the Neve Series 5 console 32x8 or so not having fully assembled it. Also perhaps as many extra input modules!
It was all to be dumpstered Friday.
Now to see how much we can get working! Or it may actually end up in a dumpster! Or recycled, as per the current rules.
I suspect we will build a few chassis to hold the additional Neve input modules and sell them off as input strips.
Most of the rest was video gear for others to take, but did get some still working IBM 14" removable hard drives.
All this coming in as I am failing to give away some of my stash of parts and other stuff.
Friday we go back for the shelving!

Didnt John McLaugnlin and Mahavishnu do that sort of improvisational wandering off and coming back on time thing years ago, when I was a kid?
