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 also noticed immediate changes. Pretty big ones to. I have placed one CAST cu cap, one CAST PIO inductor and one VST Cap in my filter. The CAST PIO replaced my North Creek inductor. I had already changed all resistors to Duelund CAST. What i hear is a significant better separation, resolution and dynamics. Voices sounds wonderfully lifelike. My Fostex T500 supertweeters sounds nice and airy. I use the Duelund in my serial filter, feeding my satelites going from 100Hz and up. Bass is taken care of by my custom open baffle bass towers with 10x15" Great Planes Audio woofers.
I just wanted to mention .I have documented many ,1,000 s of hours on capacitors and changes over the years. For Resistors hands down even the standard Duelund resistors are the best,their black case models even better.
Capacitor wise I agree the Duelund Cast are the best out their period.
If you have the $$ they even make a pure Silverfoil a Silk beeswax
Capacitor that a 3.3 u.f is actually over $1,300Each . I am told a full crossover can cost $20,000 in a set of speakers.the Rolls Royce of caps !!
The phase 1 (of 5) of my duelund external crossovers is ready and working. This time only changing all resistors to duelund cast, keeping all solen caps and inductors. I conditioned the duelund caps and inductors (for later phases), but forgot to condition the solen parts with the cable cooker, so it will take several days for them to settle and be able to do critical listening.

On a different topic, I decide to rewire my dunlavy sc vi speakers. For the tweeters, already purchased mundorf solid silver gold, which should arrive in a few weeks. For the 15" woofers, I am thinking about using neotech occ solid copper 12awg. For the 8" woofers (150hz to 1khz 1st order) I am in doubt between neotech solid 12awg or cardas litz. For the 5" mids (1khz to 2.5khz 1st order), also in doubt between neotech solid 14awg or cardas Litz. Maybe neotech solid for 8" and cards litz for 5"? or should use same type for 8" and 5"? What do you suggest?

Thanks in advance.
I used Neotech when rewiring Spendor 9/1 speakers a few years ago, replacing what appeared to be multistrand lamp cord, and was very pleased with the result.
Just finished testing vintage tubes vs. Psvane and Genalex Gold Lions.

When the Genalex went in the preamp section over the vintage I noticed right away less resonance and a fuller sound. When I got the Psvanes things were even quieter when used with the Genalex's. (maybe to quiet)

The vintage tubes thin out voices wash out the sound but when first installed give the sense of air. The combination of Psvane and Genalex reveal things like the singer can not hit the note. The voice becomes much more real faults and all. Which is better Psvane or Genalex? Not sure yet...
For a couple minutes things sound better with vintage tubes but then I realize the price that is paid by all the resonance.

I am going to get another set of Genalex 12AX7's to compare directly vs. Psvane
