Why there is no manufacturer in India(Except Cadence),in the Valve Amplifier section?
There are so many DIY kit's available from reputed companies worldwide e.g.
http://www.worldaudiodesign.com/
This doesn't need any hi-tech set up.Iam surprised to see China manufacture's and supplies to the world,while we don't have a single manufacturer,to name.
What could be the reason;volume,margin?

It's all about demand and supply.

But that measure consider the no of hi end HIFI brands currently being manufactured in China and compare that to India.

Cadence amps are targeted at the serious audiophile. Not many of those around. Its a specialty product.

Secondly, not many in India have the expertise to make a product that sounds like a cadence valve amp.

chine mfgs supply it because they are the OEMS to western cos..thats all !
Apparently the cadence guy had also gone to chine forst, but seeing the huge IPR violation there decided to come to india..almost every china mfg is a OEM to a brit/german or US manufacturer.

another factor, perhaps more important as per a chinese friend is, that china has a large no of audiophiles. they are much more spending oriented than indians who are savings oriented. hence they have been spending big money on audio whike we still scringe at it..thats all ! ..just a matter of priorities ! it is only now that we have started thinking thet entreprenueship is good or there are other options in life other being a Dr/Engr/MBA !

i still feel we need to mature.i mean Indians at least.c'mon the moment you talk to them about good speakers costing 70-80k they raise their eyebrows and frown.but if some one spends lakhs on a meaningless modern art to adorn his room they would go on and on praising it.....it's more of sterotype thinking..... yes it is prefernces.they give you lectures when you talk about spending lakh on a good music system.but praise you if you dump the same money on some foolish designer stuff.........

lets face it, china is the manufacturing capital of the world today. So why not valve amps ?

Indians , today do spend, its not that they dont. remember two months ago our Finance Minister put a curb on people spending becuase they were spending too much. Every audio shop had people from the tax department asking for purchase details...

So when people spend you curb them, when people dont spend you ask them to spend......

Thats the state of affairs in our country.

i have auditioned the Shanling CDP.
to me the Valve output was not very great..it looked better than it sounded, but the Solid State output was pretty good.

I have heard that they become phenomenal after modding..but they are a bit expensive

check out Xindak products for a low cost option...

Hey Arj,
That's exactly what I was trying to say.China benefits not just from being a VFM OEM, but also has the added advantage of having an enormous domestic market.Take cellular phones for examples, China has a subcriber base of 305mn, as against 50mn in our country.

Anyway here is a suggestion, why don't we organise ourselves into a pressure group and lobby Manmohanjee,Chidambaramjee and Montekjee to reduce import tariffs of HiFi gear with the end objective of coverting the vast majority from "remix" garbage to refined music.

Manek can be the Chairman

What say you folks

Guys,
total waste of time, do you think this country will ever change???????

My dad who is an Extra Master (above Ship Captain) has been in the merchant navy for many years travelled all over the world and today he is 76 years old. He had a chance to settle down in Singapore many many years back in his hey days, but he refused to move all of us lock stock and barrel as he thought that "MY INDIA WILL CHANGE FOR THE BETTER" & thats why he decided not to settle down for good in Singapre, guys I am talking 1973-74.

Today he tells me that he made the biggest mistake in his life for staying back in India (GUYS THIS IS PERSONAL) So pls dont take it to heart.! India has never improved and he tells me to get out and see the world, how the other countries have progressed & were INDIA stands!!!!!!

Today guys to be very frank, I am trying like hell to get out. I feel I am too over qualified and we are ten years back in audiophileland compared to other countries.

Do you actually think that our politicians will listen to us, they are interested in making money for generations and thats it.

thats why my saying is: MERA BHARATH MAHAN!

Sorry to be rude to anyone, but those who dont agree, thats upto you. End of story.

If I go on it will be forever so lets end this damn topic here. No wonder all the youth want to get out of this country.!

well..tthis is Off topic but in the past 10 years I have lived in the the US, Europe as well as Singapore and agree that living there has its high points (Especially as a Audio lover ). but to me living in India is something else and whenever I am abroad (Which is too aften these days) I just yearn to be back..hence never took up the options of settling at any of thos places

So different strokes for different folks and One mans fish..etc etc and all that holds true here I guess !

I sincerely believe that India has progressed in the past 10 years and every time I come back I can see the difference which has come up.
I feel my quality of Life is Much higher in India (Yes very true..most places abroad a Maid/driver etc etc are Unaffordable)
I genuinely feel that as an individual i have more rights as well as am more independant here and am actually a first class citizen with all rights(I am sure it is all in the mind..)

yes there is corruption/negligence/dust/pollution etc etc..but just that is not enough to get me to leave..!!!

with the manpower we have here and the the raw materials.yes we can progress much faster.there is no doubt that it will happen some day.but iam too selfish as I want to see those good days when iam alive and not after i R.I.P

it's not just the audio stuff ,every thing seems to be indiffrent.but as arj mentioned I love to be a first class citizen...i mean king of my own lil kingdom,.....
c'mon guys we can beat all other brands as with cadence stands head to head with the big names.we need more .....I mean we deserve healthy competition among ourselves.....and rest of world buys stuff from india :D.i guess then i will have dealership for Indian brands in germany or britain ...busy selling indian made stuff.of course the premium stuff....

Different people would have different takes on this, but, having lived in India and abroad for a number of years, I would whole-heartedly agree with Prithvi.

Quality of life – well, depends upon how you define it. Developed nations have made systems/processes so damn user friendly. Life is valued there and steps taken to protect it continually. Hired household help is available everywhere. Drivers, well, my car is much better than anything I could get at even three times the price in India, and the roads are so much better, India cannot even think of coming close, so who needs a driver? First Class Citizenship? IMO the only ones enjoying this privilege in India are politicians, Govt. officials, thugs and goons and not common law abiding citizens.

I too would love to see India at the top, but with the kind of leaders we have, that seems to be only a pipe dream. On a daily basis, as well as in the long run, to me it is a no-brainer that developed countries have a lot more to offer to an ordinary individual than India does.

Yes guys, I agree that we are 2nd class citizens in other countries, but people respect you for what you are and what qualifications you have. Never in any other part of the world will you find a electrical engineer drive an auto, but in india you will! Yes happend to me, the guy spoke fluent english and I asked what the hell he was doing driving an auto and he said that he could not get a job, bcoz everyone wanted experience and you cannot buy experience.

Well yes I too love india for the people, the warmth and the fact that ur are the 1st class citizen, but>>>>>>>>>> what about the other problems.

Just let me give you a small example:- When I was in Spore for the show, I met my old friend for at his place. Then we both walked to a bus stop, he already had a credit card (pre-paid) for the MRT & BUS, all he did was wave it in front of the machine inside the bus and it knows at what stop you entered. Well as I did not have the card, I had to to drop a few pennies into a machine and out came my ticket (no bloody bus conductor, saying CHANGE ILLA Sir!).

When we got to our stop that we wanted to get off, my friend just waved the card again at the exit and the machines knows from where you travelled and where you got off. We got off near DOBHI GHAT which is a subway station. Guys thats the real name in spore! Again as I did not have the card, I put in $2 into a machine and I got a card, which I waved in front of the machine at the station and so did my friend and we got into an MRT train (no train driver) whole train air-conditioned, LCD TV inside, with great music and announcements as to which station is next and on which side the platform will come, etc.

We got out and again both of us waved our cards and then I went back to the machine and put my card into the machine. The machine ate up my card and returned my change of 80cents, as I had used only 1.20$. And for my friend, as he had used the bus to come to the station, his fare on the train was less by 30%, why???? Beacuse he used the bus.

Now look at the trains in MUMBAI! and imagine yourself.

Period.

I blame our huge population & the chalta hia! attitude! This is my last post on this. !!!!

His DIY valve amp just finished the MF pre that he still ownes. The chassis is in development stage and very soon it will be launched. Will keep you informed.

Hi Maneck,

Since you are close to Cadence and they make Valve amps.....What is your guess on how many (Valve Amps) they sell in India annually ?

Just wondering if there really IS a sufficiently large ( to be commercially viable ) market in India for "bottles".

Anyone else's feedback too is welcome, as long as you are not shooting from the hip !

Thanks

#28 erstellt: 04. Mrz 2005, 16:51
Not too many Dinyar I would think. I really dont have the figures, neither will I be able to get the figures...

The market for 2 channel amps in India is small and the market for 2 channel valve amps is smaller, many reasons like price, power perception, reliability, HT mania, etc.

There is a decent demand for "bottles"/"valves" per say globally so a valve manufacturing plant for export may not be a bad idea, I should think. Bhel manufacturers them I am told but dont know much about the quality or whether they are exported or consumed locally..

As far as it being commercially viable "The premium" one pays for valves, justifies its production, small, medium or large provided you are able to sell what you produce. The main stay of cadence is speakers and the amps are usually not made in numbers. A few must be kept in stock and the stock is replinished as items move.

Dinyar....

Maybe 50 maybe more...dont know but there is scope for exponential growth keeping the dynamic market conditions in mind. Most importantly since audiophiles are an extremely small tribe in India, need for education is paramount.

I for one am saving up for tubes as well.

Hi guys,

Sorry, I'm late joining this discussion. Didn't realise the scene was this active.

Let's not sell India short. We are, after all, a poor country. As far as valves are concerned, it's a matter of exposure. How many of you can go to your local audio store and even audition stereo equipment, let alone valve gear. Patience is required!

Even in developed countries like the US, ask an audio guy about tube equipment, and you'll get a blank stare. High end audio is always going to be an exclusive affair - from the point of interest, not necessarily cost.

There are people doing work on valve designs in India - just give them time. And you know, the internet, and forums such as these, are making it easier!

viren is right...valves will never be mass market again. The demand though is slowly picking up for two channel stereo.

I have been craving an i-pod for quite sometime now.

Despite the glowing praise in magazines and websites on the 'net, I have
always found the bass response of the iPod less... no make that FAR less
than satisfactory. I have tried several i-pod versions ( G-3, G-4, Old and
new Mini I-pods ) and all seemed "bass shy" to me.

In the midst of my alternating lust and denial for the iPod, I received an
I-pod Shuffle as a gift and the bass was almost miraculous ( to me )
compared to ANY other I-pod. I searched the web and came up with references
that the Shuffle I-pod uses a "unique" Push-Pull ckt, while the other I-pods
use a single ended circuit.... hardly pausible.

Now there is a difinitive note with testing ( out just today ) where various
iPods have been called upon to deliver a 40 Hz square wave, and the output
measured.

Check out the following 2 links.

http://www.pcmag.com/article2/0,1759,1777890,00.asp


http://home.comcast.net./~machrone/playertest/playertest.htm

The truth seems to be that the I-pods use a dimunitive Output coupling
capacitor ( I suspect to squeeze it all into that lovely, small package )
but Bass has been the victim.

Only the I-Pod shuffle probably uses a split rail power supply with direct
coupling into the Head phone - like most modern Audio ( Hi Fi & not so Hi Fi
) amplifiers.

It would seem to me to be a simple matter to rig up a buffer amp or better
still, a Quad Op Amp chip with a few resistors and little else as a Bridge
amplifier that will directly couple into the I-Pod phones ( without a split
rail supply ) , and also provide double the Output swing into the phones, as
a bonus.

The bridge amp could be fed from an external 9 V battery or better still
from the I-Pod's battery. I suspect that the I-pod does provide an external
DC voltage for the external "remote" wired remote control ?

Given the brisk sales of i-Pod accessories, this one may reward enterprise..


Can anyone help me with this ? ( The Pin configuration ? )

Any other thoughts and suggestions welcome.
