Need help with DIN to RCA phono cable troubleshooting

Dear Dover, Which method  should be used to connect the XLR

connectors? Should the ground wire from pin 5 in the Din5 connector

be split in two such that each can be soldered to the pin 1 on the

XLR connectors? Or should only the (floating) shield of both

channels be connected to the pin 1 on the XLR connectors?

Totem  395, You both are right. ''Some'' (quantor) is true if there

is at least one object (aka ''entitity'') which satisfy given condition

(someone has stolen my car. Dover is the person who deed it).

''All Volt meters will burn out the coils'' is not true if there is one

Volt meter which does not burn out the coils.

To me an Volt meter is as important as the stylus brush. Those

are the se called ''neccesary  intruments''. Consider checking

those coils in advance instead of doing all the adjustment work

a priori and discovering afterward that the coils are defective.

Dover thanks. You are an excelent teacher.

My Gosh, I feel, so to speak, as involved in a dispute between

Stalin and Beria. Those two were the highest  authorities in the

''good old Sovjet Union''. However we also have our authorities

in this forum while I have some experience with communist regime.

According to this experience I should pretend to be deaf as well

as mute and wait for Dover's response.  

I agree with comrad Dover. Not because I fear for my life but

because he promissed to me some of this New Zealand's

''holy water'' which I certainly can use at my age.

Well I hope I will not add to further confusion but I made myself

some of those ''symmetrical single ended ICs''. Not political or

ideological but scientific explanation is as follow. The shield around

(two wire) which is connected to only one side of the RCA

connectors is the so called ''Faraday cage'' with electrical property

to protect the signal  from outside ''disturbances''. Some IC's

have marked arrows which suggest the direction for the connection

which should follow the source signal. This can't be done by a

phono-cable so we must connect the other way round: at pin 1

of the XLR connector. The strange looking expression ''symmetrical

single ended IC'' is the name for the cables with such shielding

provision. A name is not predicative qua linguistic nature but

has only the function of reference.

For my Reed 3P I ordered by Vidmantas symmetrical (aka XLR)

cable. I own Basis Exclusive phono-pre which can be used both

ways. All my previous Reed's were single ended. To see for myself

I unscrew one of the XLR connectors and was able to see clear

that both (of two) wire were connected to pin 2 and 3 while the

shield is connected with the pin 1 with the help of an soldered wire

to the shield. There is no ground wire by my Reed 3 P but there

is also no Din 5 connector involved because the cable is all the

way from the cart to the phono-pre. However I could not see the

other side of the cable and have consequently no idea if the

shield is connected  to the arm mass.

Dear Dover&Atmasphere, Instead of quarrel about ''who knows

better'' your duty as the old experience members is to teach the

other members. For every member who would like to try symmetrical

connection the following information is necessary. First is the

question what condition need to be fulfil by a phono -pre to be

called ''symetrical''. XLR connectors on any pre don't ''imply''

symmetrical kind. Second in order to modify single ended cable

and exchange RCA for XLR connectors one need to know how

to do this. For this purpose I asked Dover my question about

the ''right method''. I think that those ''Neutrik'' XLR connectors

are better than any RCA while much cheaper at the same time.

So everyone who owns an symmetrical phono-pre can try

to do this by himself. BTW those XLR connectors are more

easy to solder. Atmasphere should explain why symmetrical

sounds better because there is no consensus about this question.

No consensus means confusion.

The fact that each cart is an ''balanced device'' is not sufficient

reason to mess with connectors and cables. Without any reward

there is no sense in the effort.

Atmasphere, Our great teacher Dover deed not comment on my

question about possible benefit of the symmetrical connection.

As I mentioned before there is no consensus about this ''benefit''.

To put this otherwise: there are many who believe that there is

no difference in sound. You are an expert in symmetrical amps

so you should explain those benefits in the context of  ''full

symmetrical phono-pre'' which is much more expensive to make

because on need twice as many components than by single

ended phono-pre. If this is correct than the ''argument'' about

the price of single ended cables is circular. What one may save

on cables one will lose on the amp.

BTW I also own Klyne 7PX 3.5 which has very good reputation.

This amp is single ended because Klyne is one of those who does

not believe in ''symmetrical advantage''.
