I finally made some time to fix my pair of 'beater' DSP5000s. We are having a party next month, and I thought it would be great to see if I can fix these and put them outside to play music. These were old speakers that were 24/96 upgraded from the 18-bit versions and developed some noise from the tweeter that got progressively worse with time shortly after I got them. Based on feedback from others, I suspected the amps needed servicing.

Special thanks to Tarik and Tyrone on here for some pointers along the way when working on DSP5000s. It was my first time recapping a speaker amp board. I successfully replaced all of the capacitors and did the load resistors as well. I did not see any bulging caps, but could see some discoloration on a few and the load resistors were badly burned (as expected).

The difference is night and day- the noise and warbling from the tweeter is gone and they went from my worse sounding pair of 5000s to my best. I am so impressed with the clarity and sonics, I think I will replace the caps on the amp boards of my Smiley DSP5000s. I used Nichicon golds or ultra fine golds and went with Supersounds per this thread. I am noticing the biggest difference in the highs, but overall they really sound amazing! It is actually hard to believe they are the same speakers.

The difference has me wondering how much improvement I would get from refreshing the DSP6000s? Similarly, I have an old pair of DSP6000s (probably from the early or mid-1990s) that were upgraded to 24/96. There is nothing wrong with them and they sound fine, but I wonder if there is any improvement to be gained by refreshing them. Has anyone taken on the DSP6000s?

I've re-capped a number of DSP5500's and DSP6000's with excellent results.

The process is very similar to that of the DSP5000's...
All the capacitors need to be changed (some 38 capacitors!), check the resistors (but they're normally OK)
There are two separate amplifier boards, four large power smoothing capacitors, and a smaller power supply board.

Drop me a PM and I'll send through a list of components. It's not cheap, especially if you replace the four large smoothing capacitors but there is certainly a noticeable improvement in sound.

Cheers,
Steve

Hi all,

If anyone feels they don't want to take on this kind of work on themselves, feel free to drop me a pm on here, or use the Contact Us section on our website. We would be happy to discuss any requirements with you.

Just so you are aware, apart from offering a full re-cap/service for DSP5000's, I'm currently doing the same service on my second pair of D600's.... in a month!!

Thanks

Russ
