Since the 90's I've always dreamed of owning a pair of these legendary speakers. Recently I saw an ad on Craigslist for a pair of excellent condition DSP5000's in cherrywood. The cabinets are near perfect and they were kept by one owner, seldom used, in a nice home for many years.

They're the oldest iteration, with 1993 stamped on the back. The seller told me they worked but that he was selling them "as is".

I got them home and hooked them up to a Sonos Connect (digital coaxial out). The speakers turned on and played music, but they also sounded anemic and not quite right. There's almost no bass and I get the sense that less of the vocals than should be are coming out of the top tweeter. But I'm not an expert and I haven't listened to a pair of these since the mid 90's. The pair was previously hooked up to a 562 (which I don't have) but I reset them into Type 5 and all the adjustments (tilt/bass/etc) are at their default.

Is there a way to determine what, if anything, might be wrong or need replacing?

Are there things to look for, listen for, or sound tests to run? I don't mind getting my hands dirty and fixing them up if they need fixing but I'm very new to all this and would really appreciate some guidance.

Thanks!

Hi and welcome to HH

I am no expert but I suggest that baring in mind that the units are over 25 years old, they could really do with a good service which may include capacity and driver replacements.

Although we luckily have a number of very able people to service our equipment over here in the UK, I believe Marc Koval - The Repair Shop is on your side of the pond. I suggest you check out the Service, Repair, section on here to make contact.

Hope that helps

Jon

I have bought four sets of DSPs for a total of 11 (9 5ks and two 420s). Six came from eBay. I have not modified them in any way. They all sound fantastic, even when driven by a Roon ROCK hifiberry. Like "best speakers I ever heard".* So it sounds like either your source is dodgy or your speakers have crossed the line from "old and could use being recapped" to "broken". I've never done it myself, but whenever I read about someone recapping their speakers here, they are starting from "this speaker works and sounds good", and finishing at "wow, this is fantastic". You seem to be starting from a place of "this is unlistenable".

I think the lesson is, if someone says "It works, but I'm selling it as is", then it doesn't work. When I buy on eBay, I only buy things that are listed as "working". If they say "Its working", and then write "but I haven't tested it", then they are taking the risk, not me: eBay will accept the item and refund my money if it does not, in fact, work. On the other hand, if someone sells it "as is", but writes in the comments "It totally works", then I don't buy it. If it turns out that it doesn't work, there is no legal recourse.

IANAL, but if there was only a verbal contract, and that contract was "It works, but I'm selling it as is", then sounds like you have a strong case that they told you it's working: sure, they said "as is", but they also stated that "how it is" is "working".


* To be fair, I deliberately don't listen to demos of >$10,000 speakers on the rare occasion that I have the opportunity because I like that I own the best speakers I've ever heard =)

Hi,

It does sound like the speakers would benefit from a capacitor refresh and changing the load resistors.

Have a search for Tarik's excellent guide on carrying out this work and if you feel confident to undertake the work, then get your soldering iron out! If not, find a local repair store and a print out of the guide and get a quote for the work to be done.

If the sound is coming out of the speakers, they should be repairable. The only issue will be if any of the bass drivers are faulty as these are no longer available, but replacement tweeters are.

Good luck with the repairs.

Steve

It sounds to me like the speakers have an issue. DSP5000s are wonderful speakers, and I also have several pair.

I have had excellent results in refreshing the caps on the amp boards of DSP5000s and DSP6000s, and maybe you saw my post in another section. Both of those sets were older (probably from around mid 1990s and were upgraded to 24/96). Potentially, you need to service the amp boards and it could solve your issues. In my case, the 5000s had a bad warble (noise) in the tweeter, which was solved with new caps. Afterwards, I noticed an improvement in the bass as well. After the service, both the 5000s and 6000s sounded incredible.

I think your best bet is to try to return them if you are not happy. If the seller will not take them back, you should probably have them serviced by a professional.
