New Power Cable on a 1990 Hafler DH120?

Not sure I’d spend too much a 25 year old amp, but a better PC can definitely make a difference.  I’d recommend trying Cullen Cable as they’re a solid upgrade over stock cables but don’t break the bank, and they offer a good trial period so if it doesn’t make a significant difference you can just send it back.  They just got bought by Wyred4Sound so I’d think you’d need to go to their site to order but not sure.  Definitely worth a try though.  Best of luck. 

Hafler rock solid and worth investment imo having built many back in the day. I would go the IEC route if you plan on refreshing / modifications.

Best to you, glad you are back into audio after a hiatus…..

@wlp3 I might suggest you get a really good drill bit and power through the steel and find a grommet that will capture the cable of your choice. Forget an IEC--worthless additional connection in this case and would be a pain in the rear cutting through all that steel. Go with the cable you desire and size accordingly.

I might suggest Supra Lorad would be a good choice. Go for the heavier gauged one. Flexible, easy to work with.

Also, agree with replacing those caps

Lots has changed over the past 30 years, especially civility. Very sad but there are still those out their willing to give a hand. Good luck.

PS-built a Hafler pre/power amp years ago. Good memories.

Contact John Hillig at Musical Concepts to determine REAL options for spending your money for amp improvements.

Replace the power supply caps and any electrolytic bypass caps on the individual amp channels.  You'll get much better return on investment.
