Capacitor log Mundorf Silver in Oil


I wished I could find a log with information on caps. I have found many saying tremendous improvement etc. but not a detailed account of what the changes have been. I have had the same speakers for many years so am very familiar with them. (25+ years) The speakers are a set of Klipsch Lascala's. They have Alnico magnets in the mids and ceramic woofers and tweeters. The front end is Linn LP12 and Linn pre amp and amp. The speaker wire is 12 gauge and new wire.

I LOVE these speakers around 1 year ago they started to sound like garbage. As many have said they are VERY sensitive to the components before them. They are also showing what I think is the effect of worn out caps.

There are many out here on these boards I know of that are using the Klipsch (heritage) with cheaper Japanese electronics because the speakers are cheap! (for what they can do) One thing I would recommend is give these speakers the best quality musical sources you can afford. There is a LOT to get out of these speakers. My other speakers are Linn speakers at around 4k new with Linn tri-wire (I think about 1k for that) and the Klipsch DESTROY them in my mind. If you like "live feel" there is nothing like them. In fact it shocks me how little speakers have improved in 30 years (or 60 years in the Khorns instance)

In fact I question Linn's theory (that they have proved many times) that the source is the most important in the Hi-Fi chain. Linn's theory is top notch source with lessor rest of gear including speakers trumps expensive speakers with lessor source. I think is right if all things are equal but Klipsch heritage are NOT equal! They make a sound and feel that most either LOVE or hate. (I am in the LOVE camp and other speakers are boring to me)

So here goes and I hope this helps guys looking at caps in the future. Keep in mind Klipsch (heritage Khorns Belle's and Lascala's especially) are likely to show the effects of crossover changes more then most.

1 The caps are 30 years old and
2 the speakers being horn driven make changes 10x times more apparent.

Someone once told me find speakers and components you like THEN start to tweak if needed. Don't tweak something you not in love with. Makes sense to me.

So sound
Record is Let it Be (Beatles)
The voices are hard almost sounds like a worn out stylus.
Treble is very hard. I Me Mine has hard sounding guitars. Symbals sound awful. Everything has a digital vs. analog comparison x50! Paul's voice not as bad as John's and George's. Voices will crack.

different lp
Trumpets sound awful. Tambourine terrible. Bass is not great seems shy (compared to normal) but the bad caps draw soooooo much attention to the broken up mid range and hard highs that are not bright if anything it seems the highs are not working up to snuff. I have went many times to speaker to make sure tweeters are even working.

All in all they sound like crap except these Klipsch have such fantastic dynamics that even when not right they are exciting!

Makes me wonder about the people who do not like them if they are hearing worn out caps and cheap electronics? Then I can see why they do not like them! If I did not know better from 25+ years of ownership that would make sense.

For the new crossover I have chosen Mundorf Silver in Oil from what I have read and can afford. I want a warm not overly detailed sound as Klipsch already has lots of detail and does not need to be "livened up" they need lush smooth sounding caps. Hope I have made the right choice?

When the crossover is in I will do a initial impression on same lp's. Right now it goes from really bad (on what may be worn vinyl) to not as bad but NOT great on great vinyl. (I know the quality of the vinyl because tested on other speakers Linn)

The new caps are Mundorf Silver in Oil and new copper foil inductors are coming. I will at the same time be rewiring the speakers to 12 guage from the lamp cord that PWK put in. PWK was a master at getting very good sound often with crap by today's standards components.

The choice of speakers would be a toss up now depending on what I am listening to. Klipsch vastly more dynamic but if the breaking up of the sound becomes to much to effect enjoyment the Linn would be a better choice on that Lp. If I could I would switch a button back and forth between speakers depending on song and how bad the break-up sound was bothering me.

Duomike,

What size of wires did you use for the tweeter and mid? It is hard to find Audio Note wires in the States.
Thanks Duomike. I also changed the Auricap with Mundorf gold/silver/oi; in a pream. And the result is great. The Mundorf is much better than the Auri. Next i plan to pour lead shot in the frame of duo.

Duomike: try to put dynamat in both cylinders of mid and high. I think it makes some improvement too.
I try to replace cap in the teewter of my Advantgarde Duo 2.0 (currently having mundorf). Please advise me what model of Deulund cap should i buy.
Thanks Duomike and Volleyguy1 for your advice.
Volleyguy1: As you explained in the above answer is the combination of one Cast and ona VFS because i need two of them in a tweeter. Do they need to be in order? because i never open the back cover of the tweeter before.
Duomike: Do you have procedure/trick to open the back cover (especially the binding post)?
Charles1dad:Where did you order your Duelund cap to get 20% off?

Duomike: Did you upgrade cap in the mid-range of Duo too?
Finally the Dueland cast caps arrived yesterday. They are physically ways bigger then Mundorf Supreme. I thought i have to return them but i think i can manage to store 2 of them in a tweeter (Avantgarde Duo). I have questions for you and need your helps.
1. Due to the location i have to extend the lenght of terminal wires of the cap by welding more wires on each terminal( 3 to 5 inches). Does it effect the performance of the cap?
2. Porarity of the cap: i do not see neg/pos marked on the crossover board and also is the Mundorf caps. In addition, the Dueland Cast does not mark either. Please advise me how to connect the Duelan to the crossover.
Grannyring: no they do not send wire. I may reuse some of interconnect wire that i have in stock by combining several connductor together to make the same gause as the wire on the cap. What type/guage of wire you recommend?.
Yes, i can solder.
Duomike, i plan to hang the caps on the cross bar inside the tweeter and solder the tweeter wires directly to the xo to eleminate the quick terminal connector.

Thanks for your sugesstion. i have to take a closer look on this and see if room available and structure that is able to hang and tie the caps since the Dueland is very big. How long does it take to burn in the cap?
I just ordered some of copper hook-up wires at VH Audio. I just think the Dueland leads are copper so i go with copper.
Thanks for all responses.
Duomike: Did you replace the jumper wires from the XO to the driver on both tweeter and mid-range?
Just completed mod of my speakers by soldering all internal wires, dynamat, and especially replacing Dueland Cast. What i can tell you that just after ten minutes of warming up the system, i played some favorite song and said WOW..Oh My G....The system is up to the next level. Mid gets better but high is a huge improvement. It is more extended, natural, organic, air, and detail from the high. Hearing some that i never heard before. These Dueland Cast are awesome!!!Thanks you all for the inputs.
Duomike,

I do not want any sand because i am filling the material while all drivers are still on the frame.

Theaudiotweak: can you explain more why you still want resonance and for that uses steel or bronze.
Chadaffect,
I bought dynamat on Amazon. Like Duomike said, it is the stuff people use it on car stereo by stick them on door, hood, floor, and trunk.
Charles, let us know how the Jupiter sounds in your system. I did the same like you with Dueland cap in tweeter and I loved it.
