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.

Thanks Dave. Those new SET's are looking better.

Thanks Wavetrader good review. A Fisher adventure is not what I am looking for?! The only upside is replacing caps that are almost 45 or 50 years old is not a waste. Of course this lowers the value of the amp not raises it. The 500c is for livingroom anyway and I do not like the way it sounds so not a waste.

My problem is now simple too much high freq noise blocking enjoyment. When you have a amp that is pitch black and you can hear around a instruement that is addictive!

My experience is that with these ultra low noise caps...they are real sensitive to power quality. Maybe a hard wired component will suffice....but I have converted all my vintage to IEC 3 prong receptacles. I would not use a hard wired component....Now Mac users would disagree but with my vintage Accuphase....made me a beleiver...

Volleyguy,

Yes, aren’t the CAST just fantastic? I was shocked myself…

I consider them the best upgrade I have ever done.

Happy listening.

Stormen the CAST are AMAZING!

They are dark and quiet when you first get them though. Also they are hard to get a handle on.

A friend was by tonight and I did not tell him which speaker had the CAST in. At first he did the same as most do. He liked the VSF. After awhile he changed to the CAST. Which makes me think we like resonance at first then once our brains can process what is going on we like prefer the low resonance.

He said it was like the speakers were "full range with the CAST and noisy with the VSF".

The downside to the CAST is and there is a downside in my mind. They will not cover up your amp or source!

I will end up getting rid of at least half my vinyl. The CAST are excellent as they are ULTRA low resonance.

The strange side effect to me is I may end up selling my turntable not because there is anything wrong with the Lp12 but the CAST have revealed that my vinyl is MUCH more worn than I thought.

What the CAST have shown me is maybe vinyl is not the way to go at this level. My very good vinyl sounds fantastic! My less than good vinyl is torn to shreds by the CAST.

There is no hiding and pretending that the vinyl is Ok.

My Karik has finally quit opening so I have only an old CD player and the CAST tears it to shreds as a piece of garbage. (which it is!)

For horn speakers (which is of course what mine are) the CAST are miles better! The VSF sound all washed out by comparison. Everyone who has heard them wondered if the speaker with the VSF was broken! No kiddding.

The CAST tilt the sound downward by the MASSIVE reduction in noise. So if you get CAST be expecting that because you will get it. It speaks volumes that given a choice with one speaker on VSF tweeters and one on CAST I am very content to always listen to the CAST.

I agree with Stormen and although I have not traded the VSF's away I can easily see why one would consider them one of the biggest upgrades one could do going from VSF to CAST. Who would have thought??? Not me!

So much for the theory of dimishing returns.

Another interesting thing is many say horns do not have bass. I think by nature horns amplify sound. Since most noise is in the high freq the horn will exagerate that freq. So the horns sound like lack of bass. The CAST through the huge reduction in noise change the tonal balance down. The CAST have given a side benefit and that is correcting a weakness in my speakers.

I am going to have to hear Burt's modern horns. (not buying anything soon but am curious)

I feel the CAST tweeter caps very good value but the midrange with out hearing it that is a lot of coin! For my speakers it would be $2200 plus tax and shipping for mid range caps. Silver CAST would be $15k for the pair! Holy Crap!

After hearing CAST I must admit it would be haunting to know how much noise they get rid of and putting coin some where else in the system. If your caps are noisy (and even VSF are noisy) how can you get the most out of your system?

I want to thank everyone who has helped along the way.

After looking at those CAST prices I do not want to even contemplate. I am going to put one CAST and one VSF in the tweeters and finish the rebuild and wrap this up.

I am moving on to tweaking up the amp and maybe a top notch digital front end and no vinyl. Maybe.

Thanks for all the help!

Now it explains it... Well I see where your true issues lie...

Your in need of some real electronics my friend no offense.. Your simply trying to pry some very old and distorted equipment back by now "covering it" with good filtering..and re-capping it. This includes your speakers and old vintage gear.

No doubt your cast caps are good, but the VSF's are just fine in a system with the right amps..

You need to seriously consider not wasting another 2000 to 3000 on more caps to cover up raspy horns driven by mediocre equipment to get this "Magical vintage sound"

To me it sounds that your money will definitely take you furthest with a minimum of getting PURE Class A Mono blocks Solid state or good stereo amp class A, Yes one made in this CENTURY!

I think your fighting a difficult battle on several fronts, not just reviving your old speakers or gear with all this re-capping exercise..

As for vinyl thats almost silly, not sure if your cleaning and setting up everything correctly.. As a matter of fact the Cast caps will take most vinyl to a Higher level not the other way around. Cleaning machine, good vinyl rig, and nice amps to actually drive your speakers will cost you at this point what you want in bandaid approach of capacitors!

Don't get me wrong the right mix of caps especially in the right crossover is great for really getting the most out of your system, but I think you need much more work up front if the VSF cap sounds distorted!!! Ha, thats just insane, or that speaker is really very colored being older horns. Most that do this stuff, amature or professional reading this thread I believe would agree at this point, so please save yourself before coughing up such ridiculous amounts of money on more caps when it can get you a first class system instead of all this shot in the dark hopes of re-viving more!
