Resistor Sound Quality?

[marce]

This tread is a joke. If you can;t hear difference between resistors then skip Hifi.

Your comment is a joke and an illustration of why audio as a hobby gets so much grief.... have you proof that you can hear differences between resistors or are you like many of the GEB so convinced in their infallible hearing that reality has to take a back seat.

OK,

How do directional couplers work?

Just wondering, thought I would ask..

microwave and audio yeah go for it they are so relevant!
So directional cables then, what's your take.....

 

[marce]

Bi-directional property

Any directional coupler is bi-directional, that is, it performs equally well when the signal is incident on port 2 versus port 1, but the coupled and isolated ports flip. All direction couplers are bi-directional, unless you terminate one of the ports. Consider the coupled-line coupler below. Port 4 is the coupled port when a signal is incident on port 1, and port 3 is the coupled port when a signal is incident on port 2.

Just read #992

It is easy to see where you are coming from.

(1) Can't spell thread right

(2) Start out utterly dissing the thread and its participants

(3) Make the broadest possible generalization about parts and people

Just guessing here, but probably not the best way to make friends and influence people.

Arny, perhaps you might limit your criticisms to technical issues rather than the spelling of someone whose native language is not English. Otherwise, you might not make friends and influence people.

 

[marce]

Yes thread gently.....

 

[billshurv]

Just to stir the waters some more. Based on the numerous examples out there in tech papers from suppliers such as TI, AD, Vishay etc, it would suggest that there is more performance gain from getting the layout right (or should that be potential loss) than from special passives.

 

[jacco vermeulen]

You require a tech paper for that ?

Altering layout can save a THD bundle on an AP read-out, but why settle for one or the other ? (Dales are indeed mighty-fine sounding resistors)

 

[billshurv]

Dales at 10c or less a pop are hardly boutique grade!

I don't require a tech paper, just stirring the pot. I would also pay someone to lay out a board for me if I wanted ultimate performance as I'm not good enough at it.

In my humble opinion a lot of fashion audio layout is not good, and quite often an open invitation for RF, EMC and other problems...

Now as intermetallic's etc. have been mentioned let us add PCB surface finish to the equation as this will have a bearing on what intermetallic's are created at the soldering phase....

Now we can discuss surface finish and effect on sound

 

[billshurv]

Gold finish gives better high frequencies and a lush soundstage of course!

 

[jacco vermeulen]

hardly boutique grade!

(neither were Roederstein Resista and Holla-For a Holco)

 

[billshurv]

NOS holcos are around 35p as are Resita. In fact NOS Allen Bradleys are similar price even. No one is hurt, not even defenseless wallets.

DUELUND CAST at £32 each OTOH... Makes the £12 audionote tantalums seem a good deal.

When I attempt to write in languages other than my native English, I am embarassed by my errors as I should be.

 

[nicoch58]

my new signature sound good

 

[DF96]

If it sounds good it isn't hi-fi.

If you can hear a difference between resistors, then please document and make replicable.
