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.

Some of us also also prefer the 14 and 10 gauge WE options for more of that midrange body and fullness. I also found a dual run of the 16 gauge better sounding than a single run. They all sound a tad different and all these options are first rate. It does really depend on your rig and personal tastes. 

The best find I have ever encountered in audio for sure in terms of bang for the buck! 

Volleyguy,
If you ever decide to go the DHT SET route be sure that it has a good quality output transformer and stout power supply. Those are the make or break variables for this type of amplifier. The last two areas to cut corners. I bet Grannyring  (Bill) could build you a superb SET amplifier 😊
Charles, 
I feel much better now reading that Jeff says 

"It comes as a complete surprise to me that changing one capacitor or resistor in the circuit of the MX110s makes as much difference as I hear when swapping between entire components like preamplifiers or amplifiers in my hi-fi systems".


It is nice to have someone say the same thing as I have been saying indicating it is true or we are both crazy!


My one Fisher is back with 4 changed coupling caps, one new resistor, 4 power tubes now the new Tungsol vs. EH 7591 and changed to fixed bias from cathode bias.

My repair guy did not know if I would be able to tell the difference? (for real)

 I do not even recognize the amp!!! If you said to me it was a totally different component that would be MUCH more believable.


In the past I would have been quite upset! 

The amp was loaded with Jupiter, Jensen Copper Paper tube and VCap Cuft caps. It sounded absolutely awesome! However it has had running issues... 

More or less this amp was left over parts not making main amp which is all Duelund with Jupiter in phono stage.


The 4 caps are Solen caps. The repair guy knew I would not stick with them. They are rated around 6 is my guess by Tony Gee. 

The caps that came out Jupiter rated 13 or Jensen (not rated) but in my guess 12 or more.


In in most of my years of testing it has been a cap at a time test.

This kind of a change is just not doable... It is just so far from where it was one can not reference.

My guess is the tubes are just a tiny change. I have changed tubes and yes some are better than others but a tube difference does not equal a cap change. (Possible the different resistor)




Been an interesting evaluation going down! Really the first I have done.


When you go down the biggest thing I notice is the lack of "alive" tone. 

How easily things can sound like Hi-Fi. Really the same as I thought all those years ago on this thread. 

All foil can sound real, even vintage. 

As someone mentioned on here a long time ago your weak link is very important. 


Now I am just figuring out what to buy next. 


Moving up to CAST (2nd set on tweeters from VSF on main speakers) or Duelund Hybrid coupling caps over RS.

Best bang?





Jensen Paper Copper and Jupiter caps back in. Just one poly Solen cap left.

Waiting on Partsconnexion to get more Silver Bypass caps. (Duelund)
