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.

It would seem that the Duelund would have more effect with solid state since it breaks up the harder edged sound.. So my guess is simply you have a bad match of a SS amp for Klipsch, which is very easy to do… Use a Mcintosh or Monarchy audio SS Class A amp and you will hear the difference, at least feeding the SS with a Tube preamp is almost mandatory for Klipsch or any horns in general.

You could be right as Bryston was another horrible match to Klipsch as well. I have had Linn's lower line of amps and they were softer.

I am still in shock with the vintage tube. I put it back in this weekend. The caps will be here today or tomorrow and that may be part of the problem as quick foil caps that are worn distort. With SS (at least my SS) it may match up better with the slower poly (Mundorf) caps. Will know very soon.
Mundorf Supreme caps are in.

I will be installing tonight. Dynamics you can tell right away but it will take time to of course fully break in.

I want to get acquainted with them before Duelund's come in to understand the difference.
This is first few moments of impression of Mundorf Supreme in midrange (still Duelund in tweeters)

A little rougher in the midrange then the vintage caps. Dynamics are very close not like the change to Sonicaps. (which were MUCH less)

The mid range drone has not went away as much as expected.
Thinner then vintage so far.

Highs are not as good after going through the Supreme's.

Overall a fairly large step down from vintage in "realness". This of course is wayyy to soon to make these comments as permanent. More of a thing for me to look back on. Sound is much more grainy compared to the vintage foil caps.

They seem somewhat slower although nowhere near as slow as Sonicaps.

In the tweeter caps I thought any of the Mundorf Supreme's Mundorf Silver in Oil or Duelund's were a step up right off the bat.

Not so in the midrange? I am also not hearing the amazing noise reduction?
Sound is slower for sure and no even close to as "life" like.

Funny that the tweeters have gotten rougher sounding? The super naturalness of the speakers is gone!

Right now I am very disapointed. I hope they break in better than they sound now.

Sound is hard brittle and broke up even in the highs and what's worst of all fake. The sensational realness is gone.

The Mundorf's are not much smoother than Sonicaps in the mid range (hench the Tony Gee rating of 9) but they are much more dynamic. But if it does not improve (and HUGE) I would put the vintage foil back in for sure without a doubt.

This might make some vintage Klipsch "AA" foil caps a bargain used if you can find a decent one. They go cheap on e-bay.
