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.

I don't know of any wax paper anything quite honestly.. I don't know if anybody even makes such a thing these days.. However from inductors I have used, I have gone really stupid once and used the 10 gauge like 10 lb inductors from northcreek custom made, very expensive.. Good no doubt but found in the end probably unnecessary.. Again a Good Series thick gauge like the 12 gauge on your woofers will be plenty to give you full response without power compression from any amp.. I have driven them with 8 watts and had monster subwoofer bass out of drivers driven with 12 gauge copper ribbons.. Very efficient, and yes the effect you are kinda looking for with Clearing up the bass, and having more "Efficient" or more "Effortless" sound will be apparent with the Alpha cores for sure on your woofers.. I believe spending something like 150 or more on inductors will just be again another point of diminishing returns.. Although I have no idea what size inductors are feeding your woofers, if they are anything at about 2.5 mH or under you should be able to get a pair somewhere into the 100 or 130 a pair range from alpha core..

And yes your tweeters etc… are in parallel not series which is why you will find little to no difference in most cases, go with a nice 16 or 14 gauge if you really want to get thick magnet wire inductor, air core.. Whoever you can find is fine.. I would not spend much more than 30 to 50 bucks a pair of inductors in that case. But for your woofers being with the series inductor directly feeding the power to the driver yep you want something good, you might be shocked at the extra balance you get to keep up with those mundorf circuits once you wake that woofer up and then you might find the midrange with the mundorf is not harsh or plastic at all once you put in an inductor on your woofer, it will blend and give you more low end with better results and you might save yourself from replacing the midrange circuit again, and just keep the duelunds on the Tweets… Good Luck

The vintage inductor has what looks like waxed paper wrapped around the wires to stop vibration in the inductor.

Duelund does this same style but with air core. Duelund is all about getting the plastic out of the system. All the caps have no plastic. The inductors no plastic and I am sure the interconnects no plastic.

I am not going to spend the money to try it but would not at all be surprised to find that modern inductors do not sound as good. More bass due to lower resistance maybe but more natural sounds? I doubt it as they are wrapped in poly. The resistance difference from 12 guage Alpha and vintage is not that great.

Keep up with Mundorf's! The Mundorf's are wayyyyy out their league compared to vintage. The foil caps are MUCH faster smoother and sound way more real with much better timing. The Duelund's are just a modern version of the vintage and they are better. (in the tweeters anyway)

Undertow believe me this is not what I expected. I thought when the Mundorf's went in I was going to decide if they were good enough to not get Duelund. Never in my wildest esxpectation did I think they were not going to be as good as the vintage foil caps.

I am getting Duelund's just waiting for the call from partsconnextion. It is whether it is VSF or CAST that is the only choice.

Undertow it is plastic I am sure of it.

That is why Stereophile praised the 500c. That is a receiver for pete's sake, hardly the be all of any company's line. I think the plastic has more effect than anything. Can you not sense the disgust in the reviewers words when he was talking about vintage (receiver) from dead guys with ears being better than anything today at mega $. That is a huge stab at modern methods for sure. When you are a adverttising magazine and you say a comment like that about a company that is out of business (so they can not advertise) against your current companies you can bet he took heat for that.

Running the Mundorf Supreme's 24/7 now for awhile.

At least 50+ hours now.

I have put back in the vintage foil caps in the midrange.

The sound is much smoother voices more real. Instruments do not have that jagged edge of poly caps. All poly caps I have tried are the biggest downgrade you can make to the sound.

I have put the order through.
I went with Duelund CAST midrange and 2 Duelund CAST tweeter caps.

I could not pull the trigger on the inductors. Although I am sure they are an excellent product I just do not know how much better they would be then current vintage inductors or Alpha or Mundorf Inductors. I know the Poly affects the sound but I do not know how much on the inductor it does. I think Poly is a skin effect thing and that is high freq. At Alpha or Mundorf prices I can try and see if they are better than vintage at Duelund prices you just have to know what the effects are going to be.

The Teflon caps are here.

I am going to listen to some vintage mid caps put the Mundorf's back in and then leave the Mundorf's and bypass with Russian Teflon.

So far favorite tweeter caps
1. Duelund/Duelund
2. Duelund/Supreme (maybe Silver in Oil after time the tilt to the high end calms down)
3. Supreme/Silver in Oil (only have one SIO)
4. Sonicaps
5. vintage (wayyyyy to much noise)

Fav's in the midrange (Duelund not here)
1. Vintage Foil caps that come with speakers (by a long shot)
2. Mundorf Supreme (dynamic but fake and rough sounding)
3. Sonicaps (not near dynamic enough

I have no idea what to expect of Teflon as a bypass.
More to discover
