New Power Cable on a 1990 Hafler DH120?


Is it worth putting an upgraded power cord on my 1990 Hafler DH120?  I am considering upgrading because it is rather old.  Still sounds good IMO.  Maybe I could get some better sound with a new cable.  Considering a GR Research cable.

Thoughts?

Have fun. Cord will certainly cost more and do less.

 

Some think zero, others disagree.

Certainly the other mods you suggest would make real differences.
Including the outlet.

Compared to the cord, they are useful things. 

@itsjustme -

       In my book: informing another on ways to prevent catastrophic failures (ie: upgrading rectifiers, etc), BEFORE they cause them (ie: by installing biggest capacitance possible), is simply sagacious, but- that’s just me.

              A transformer failure is a real possibility and much more expensive than $3.00.

              But then: why should YOU have, "worries", about THEIR results, right?

                                                              ie:

So, with a big, heatsinked 35 amp bridge i have put 1/4 Farad (eread that again, yes F) in a DH-200. and if you do blow it up its $3 online for a new bridge. SO A GIANT "MEH" TO THE WORRIES.

Thanks to everyone for your input.  It spoke to John Hillig at Musical Concepts and he is really the Hafler upgrade guy.  Lots of experience.  I think I will have them upgraded by John for a second system.  Thanks to BPoletti for the contact.

                                            Happy listening!

Rodman - Your concern for the OP's gear is fine/ But please dont call my intentions into question. I was clear - I have the experience to tell him that the risks were small to nonexistent.  Why? its too long to get into but begin with the fuse and the effective series resistance of the transformer, combiend with the exponentially decreasing load of the charging capacitors.  with reasonable sizes, say 33k-50k uF, its simply not an issue. It simply can;t pass enough current to kill itself before the capacitor are charged. Even if it DID continue the fuse would blow.

 

Which brings me to the real reason for protection - which i suggested, although you conveniently ignored it.  Or maybe didn't understand it - i cant say.  The REAL reason, IMNSHO, is that once a bigger capacitor storage bank exists,a larger fuse is required, therefore less protection for myriad faults.

 

I believe the Hafler DH200 came with a 5A slow blow line fuse. My gonzo-filtered unit with a surge supression circuit, employed a 3A slow blow.  That means MORE protection.

 

I have built 100s of prototypes and experiments.  I have supervised the building of even more.  This is not idle speculation.

 

BTW through various ham fisted errors I have dead shorted the secondaries of transformers. I never saw one fail.  Eventually it will fail due to heat, but not nstantly, back to the fuse.

 

These are not mysterious error methods. The infinite current zero impedance transformer, sadly, does nto exist.  I'm still looking tho.
