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 could throw out numerous adjectives as to how the North Creek inductors compare to the Duelund Cast. But in the end what will that accomplish? From your own tests with comparing Duelund caps with others this has provided you with an education and a definitive upgrade path.
This same course of action with the inductors will yield the same results. I will say inductors are worth the money spent testing them.
I will add this about the Duelund's. They have a consistent sonic signature throughout their product line. Very natural and organic. For me it is worth every penny of the price of admission.

The Duelund Cast inductors compared to the North Creek is like going from a VSF to a Cast only larger.
Get both and sell the loser here. If it is a common value you will not lose money and to top it of you improved your system and added an education in for free.
Someday I am going to try a silver Cast inductor and compare it to the copper.

From my experience the crossover is the heart of the system and a well designed crossover with high quality parts is the way to go. I make people laugh on how much I have spent on crossover parts. But in the end I laugh because they spend more on a power cord for their system then what their crossover is worth. Do not get me wrong a power cord will benefit a system. However, if funds were an issue I would not hesitate to use a stock power and put my money on the crossover.

As you have mentioned you read a ton and then just started buying the parts. I would love to hear what you found out?

Clearly you have valuable experience to share. Most of us may not ever hear CAST AG caps or whatever else you have found out. In your upgrade path clearly you must have been thrilled (or something kept you going) with what was happening or you would not have kept going to better/more expensive parts?

Like what was the most important upgrade and most cost effective. In your experience you must have that some parts were good some great and some good for the $ involved. I would imagine many would love to hear. It is no doubt part of your recommendation (and others) that I have tried North Creek.

Have you done coupling caps?

Volleyguy,

The WPIO receive the same 5 day vacuum impregnation.

We do 12 awg normally, and 8 awg on special request. (It is not a cost effective solution)

I did get a chuckle on the adding "It is not a cost effective solution"!

That is good to hear about Duelund's consistent sonic signature. (for inductors) From what I have heard (VSF and CAST) they sound similiar you are paying for a huge reduction in resonance.

That was the reason for (me) getting 10AWG North Creek less up front money.

My inductor comparison will involve only 2 at most. The other being Duelund's WPIO.

I totally agree on the crossover as the heart of the system. Something I never would have thought before.
