More D'Yquem Problems

Does anyone have a link to independently tested impedance curve of the O/96's?

Ok so that makes about 10 other owners. If there was a design flaw we would know it I guess.
My guess : very very bad luck with tubes.
I understand why you are so fed up.
A pair of GM70 may be the way to go.

Thanks Jerome.

When I compare the impedance curves of the Tannoy's (96db by the way) to the Devore (91db), its a bit of a head scratcher to me. The Devore has some wild swings above 8ohms and quite a bit is less efficient.

Devore:

I'm wondering if the OP's Devore's might truly not be the best match for the D'Yquem's? Maybe?

Not necessarily would we know. I doubt they would publicize that kind of information. I would be curious to know if any other D'Yquem owners have had any tube issues.
 
You have to be leery about a Japanese man giving all of his products French names. :lol:

My issues with Shindo D'Yquem amps continue. Tonight I attempted to turn my amp on and within 30-40 seconds it just died. No power at all. I have had many tube failures over the course of my ownership of these great sounding amp's but now am pretty much fed up.

It seems about every dozen or so times I go to power these up something bad happens. So far bad tubes have been the supposed cause of the amp failures. This time it appears to be the fuse as the tubes seemed ok upon power up.

After a record amount of Gold Lion 300b tube failures and now what appears to be a fuse issue I would have to think maybe this amp design is flawed. I have not heard of many tube issues with other Shindo amps so the D'Yquem may be unique in it's unreliability.

As much as I love the Shindo sound the frustration and anger with these amp's have created a situation where the tolerance of not knowing if your gear will work now far outweighs the sound quality.

Change is in my future.

I had a lot of problems over the years the whole nine yards of break downs . I found a solution solid state. If you buy good solid state it sounds great and switching it on never feels like Russian Roulette with your wallet always the loser. Tubes sound great when they work. Some people have little to no problems then their is you and me.

I have been a dyed in the wool tube lover my entire life. I went through a bad spell with my tube gear being a gigantic pain in my ass and I got mad and sold it and went SS for awhile. I had a Krell KRC-HR preamp (kick-ass by the way) and Krell KSA-250 amp. I lived with it happily for a couple of years and it was truly a joy to know that I could always expect my gear to work. And then I reviewed a pair of Raven monoblock tube amps and a Raven preamp and I remembered why I loved tubes so much in the first place. I sold all of my Krell gear (except for my KPE Ref phono stage with outboard power supply-PM if you want to buy it) and bought an ARC Ref 5SE and ARC Ref 75 and I couldn't be happier with my decision. These are the two ARC pieces I heard in Carl's room at RMAF 2012 with his Nola speakers that I fell in love with. I bought the Nola KOs last March and I think I will see them before RMAF 2014.

The great thing about the Ref 75 is that it only uses a pair of KT-120 tubes per channel. It's so much easier to maintain a tube amp that uses a single pair of tubes per channel. Buying a pair of output tubes that are tightly matched is way easier than buying a quartet or octet of output tubes that will come close to the match you can get with a single pair. And none of that would matter if the Ref 75 didn't sound great, but it does. From what I have heard, the Ref 75 sounds even better if you use KT-150s. Based on my experience with the Raven amps, I don't doubt it.

thats why i keep an NAD integrated in the closet. it has pre-out/main-in so i can trouble shoot my tube gear or in pinch have something to listen to during repairs. iv'e learned how to repair most things that go wrong (burnt cathode resistors, for one). sometimes it feels like roulette but its worth it.
 
I understand easily people who do not want to mess with tubes.
There are many SS amps that sound great.
And all tube amps have reliability issues based mostly on the tubes themselves, no matter the size of the company. Mc, ARC, CJ, Manley, Jadis, Shindo... All have their share of frustrated customers.
But still, many companies continue to produce tube amps and preamps, and many customers continue to buy them.
Is this only because of Marketing ?
No.
For a minority of music lovers, there is just no other solution than a correctly designed tube amp to get to the ultimate bliss in sound reproduction. They are ready to accept to have dying pieces in their gear just for the sake of sound quality.
Exactly like we are ready to accept all the efforts to play a vinyl instead of a digital file because vinyl just sounds better.
I have 3 systems at home.
They all use tube amps.
The only exception to this rule is when I am working at my office near the main system. I put the SS amp on ( 2205) and also for HT.
I have had many other SS amps at home and to my ears, even the best ones do not compete with great tube amps. My ears are just made for the tube sound. I am not saying that tube amps are better than SS amp. That is just a personal preference.
We have lost the sense of Efforts in our fast societies.
We are not willing to wait : at the restaurant, the airport...
We always want More and we want it Now.
I love the sense if efforts and the time needed to enjoy tube based hifi and vinyl.
They give us again the sense of efforts and introduce a ceremony part in our action.

You make many good points and you are right tubes can sound great.

I also was in Carl's room and it was great sounding I thought one of or the best at the show. Carl had like a 100,000 dollars worth of wire in that room more than most of us will ever have so that was part of the sound.

A few years ago I switched from CJ to Ayre and a Burmester phono I do not miss tubes maybe that will change but I do not think so.

I do disagree with one post that SS guys just can not wait for repairs and are well lazy . Well maybe a little lazy but the never knowing if the gear will work when I turn it on just bothered me I leave the ayre on 24/7.

I in no way look down on tube gear but the heat and odd things that they can do when not sounding right take another level of your time I do not want to be my own tech.

I like some ss amps others I would not own and if all is done fairly I think two side by side ss and tube the tube would pull ahead but not by much peace

i agree Jerome!! some guys like tubes , some guys like solid state. i like tubes and the only ss amp i ever really liked and could live with cost more than my whole system. just my opinion and it is definitely a biased(pun intended) opinion as ive home demoed a few ss amps but ive never owned one. ive been looking for a moderately priced ss amp to play with in my house. but havent found one that i would actually use.
i recently heard a very popular and talk about and very expensive ss amp , and i just couldnt believe i preferred the $2500 used tube amps i heard right next to it better.lol. its just gotta be my ears, cause i cant believe anyone buys these things. lol.
tubes rule!!!
to JJ the op, sorry this thread got off topic, please let us know how you sorted out your troubles.
tubes rule!!!
 
JJ, since you love so much the D'Yquem sound,
Imho you should do this.
Return them to your dealer for a full check up. Have the dealer change the GL300B's for JJ ones and adjust the bias. Then get them back and see how it goes. If same problem happens again then go to GM70.
Please remember : Ken Shindo was first a super specialist of 300B amps.
D'Yquem is one of the greatest wine in the world.
You may be seated on a pure jewel.
Please give them an other chance. ;)

If you can not remember having problems with your tube gear I am sorry to tell you, you have Alzheimers
