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.

Volleyguy,

I find the CAST clearly superior. I know that some who use the CAST now consider the VSFs defective in comparison. I don't know if I would go that far, but they are quite something. They do require at least 14 days of break in to sound their best as they are a little dark in the treble at first, but oh my god, when they break in...
Thanks Stormen I was afraid you would say that! I am looking to get the inductor in cast. Would that make sense? Duelund's cheaper inductor is not solid so I can see a big difference there? (possible vibration)

I have found even the VSF's needed some break-in. The first was a revalation the 2nd in the circuit took a little while to settle in.

Yesterday I actually went up to the speaker to cup the tweeter to see if working. There is no grain letting you know it is on.

I have said to friends about Steen's feelings on 50% of the speaker in the crossover and 25% of the system. The response is generally a little hostile to the notion to say the least. I do find ideas in audio are slow to change. Linn when they came out with the Keel people (Linn people) wnet crazy at the cost.

Yet Linn did the double test of cheap Adikt $500 Akito $1500 tonearm Keel $2700 (I think) was better than Akiva $3500 Ekos SE $5k

By this I just mean people were Ok with an expensive cartridge Ok with a costly tonearm but in principle against a costly piece of aluminum. I think the same thoughts go against caps and inductors.

I own a Adikt and would put the money into even better caps than a Akiva as the caps last a very long time.
Personally, I would contact Klipsch. They have a website and a customer service department. You probably could send the problem part back to them with their guidance. I would be leary of do it yourself projects. Your speakers are very good as you attest, and you don't want surprises after spending lots of money and time in do it yourself treatments. My first taste of high fidelity was in the late 50's. I am a violinist, and in high school, I hooked up with the Shapiro's..a very musical family for an evening of string quartet playing. Old man Shapiro was a physician and had a Klipschorn (mono) driven by Marantz tube equipment. I still can remember Marche Slav powering through those huge speakers.. I was hooked.
Hi Stringreen

I have contacted Klipsch to buy replacement crossovers of the originals. Klipsch does not sell caps for them. They sent me to the aftermarket guys like Bob Crites, Dean and Al K. All very nice guys. I did buy Bob's Sonicaps as a replacment.

I am only replacing the parts with same value parts and quality of original or better. The Duelund's are the first caps to make me forget the originals in every way.

I too was hooked the first time I heard Khorns. I have owned the Lascala's for almost 30 years and was almost in tears when the caps went bad. The Duelund's are a no plastic cap and better the originals (at least in the tweeters and mids are coming) in EVERY way!

Stringreen it is stringed instruments that sound out of this world! I used to play Viola (school orchestra long time ago) and since the caps are changed I am spending a lot of time playing air viola!
Cap order is in for 13uf VSF Duelund. I am like my kids in counting the sleeps!

Stormen I will need two more caps for tweeters and am looking at the CAST ones for the tweeters. I am very curious? I will be only using one CAST a side (but I am going to test two to see the difference) as I own the VSF's already. Is that where you would put the money in the first place would be in the tweeter as that is the toughest to get right?
