John Curl's Blowtorch preamplifier part II

Constellation Audio. Tell them I sent you, if you want. Nice bunch of folks.

OK, found them. They're with Altair I guess.

Necer seen that before. Looks cool.

Have you designed the line stage as well, reminds me of something you could have designed.

The power amps look like air conditioners. (Joachim, Cool? )

 

[john curl]

Different designers do different components. Demian did one of the components. Bascom King did the power amp. Peter Madnick did the preamp. I do the Orion, only.

 

[john curl]

Now, if we can go forward with resistors. I think that is where we are really making progress.

Hello

Constellation Audio is an Australian company which is new to audio electronics. To get some credibility it uses designers whose names are known in the industry and associated with the high end.

All High End companies started small. This one has the financial resources to explore pushing the envelope. All of the work is being done in the US (California actually). The ownership is Australian. You could call it direct foreign investment into a 3rd world country (the US).

Hello Damien

Good Luck with your efforts.

Looking at the products its hard to get a picture as to where the envelop is being pushed , can you say anything or would it be too premature.

We don't even tell each other what we are doing. ;-)

Orion

Hello John

What is the Orion.

AR.

Any more resistor questions, anyone? Or resistor measurement results. I have certainly been pleasantly surprised by the measured results.

 

[Joachim Gerhard]

i got resistors from Simon and they look very familiar to me. Quite big though.
I will listen, not measure if that is ok. I will use the latest version of my High Z MPP plus the Inductive RIAA. I have the resistors on Eichmann plugs so swapping is easy.
I will also get some Texas Components Naked Z Foils with the same values so a lot of work is before me. Sofar i got the best sound with 300 Ohm old military wirewound Dales. They sounded even better then the 1Kohm Naked Z Foil i have. The Z Foil where more detailed but the Dale had a more fleshed out sound i liked better.
They where not the same value though, so i will do that experiment again with the same values but different types.

Does anyone know of a QUALITY resistor like the naked Vishay, but significantly cheaper? I can't use naked Vishay's everywhere.

Let us see what Jocko has to say. The samples I sent him measure better and cost much less.

I expect there to be certain differences, but I will not say what they are so as not to influence his opinion.

I am using Vishay MBB 0207 resistors now, as a rule.

 

[Joachim Gerhard]

Here is latest information fron Vishay. Quite compete.
Listening to all this may need 10 years at last and i thought that i am a freak.
The real freaks are at Vishay.
I like the oil filled zerro temkcos just by looking at them.

Thanks, both of you.

Well, I guess we should try to go forward. I am glad that several of you have learned more about resistors than you previously thought measurable or possible. Why it should matter is something that we can only guess at. I hope that we can find something else to discuss that will not create too much concern or confusion.
