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.

Sorry dont know of any paper oil caps. I owned a 500c had it rebuilt by fischer doc, best tubes you could buy in it was fun. But not close to performance of my modern tube gear. Did ok on my vintage speaker collection. I was able to pick up some altecs off craigslist. Owner didnt know correct model num. So I thought what the heck might as well give them a look over, turned out to be model 19 and hes orignal owner with manual etc. Said he had another old speaker I saw a pair in walnut, grills covered in cat hair. I pulled grills and a near mint model 15 altec was revieled. He said he sent in both sets of woofers to GPA for new surounds. And bought both new in the late 70s. He remembered having to wait for 4 months for delivery back in the 70s but didnt remember much else. Nice set of cornwalls local to me but I have so much kit hard to find a place for it.
Volleyguy - thanks for the link. I don't want to invest too much money in caps since my speakers are temporary. I would probably leave Solens in place and upgrade bad sounding caps(according to review) Audiocap Theta (I use as a bypass 10% of value). In that case I need just 0.47u and would look for something much better. What about teflon?
Volleyguy - I suspected average performance of Solens but I bypassed them (10% of the value) with REL Audiocap PPT Theta. My review says that they are "clinical" "bright" and "forward" sounding - probably the worst possible cap but your link says that they are "sonic bargains" in the Tier B - "top shelf performers". Would you trust any review after that?
Kiljanka I can not say about the Audiocaps. I have never heard them. I also can not say if they work with Solens. I can only say I thought SIO was what I wanted and only bought the Duelund's because of the rave. I "thought" Supreme would be a workhorse cap that was good but boring but found it to be very good "with" the Duelund. My other Duelund will be here on the weekend and I will have a better grip on the effects of one or two Duelund's. I can say that you find a little about caps by what the other person thinks. Often I hear slight tilt with SIO and then when put with Duelund's not good. Of course this is only in my speakers and may not mean anything to any other. There of course is personal taste. I can say the Duelund's to me have a "live" feel like no other I have heard.

Teflon has a better rating in Electronics but I am only doing the crossovers and even then it was only out of necessity. (mine are worn out)
Thanks Volleyguy. I'm in the process of replacing cheap aluminium dome Vifas with Morel Supreme 110. Now it needs playing time to soften but is already much cleaner (underhung motor). I will decide what to do after break-in and with new interconnects (silver) I just bought.
