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.

"...the tone and timbre was not real anymore."

Several very HIGH-end amp and speaker manufacturers now include V-caps in their designs. Several of these same manufacturers have said publicly that V-caps are the best caps they have ever heard or "not heard". If the tone or timbre is off maybe you should look for the problem elsewhere. Just a thought :)
Fiddler yes excuse me of course you are right on Teflon. I do hope the V Caps sound great as I will be buying them shortly and I would be thrilled if they do. The V Caps certainly have a good reputation from all corners.

Maybe I should rephrase that to poly and not plastic (in general) as Teflon is of couse very slippery.

To be clear I should say I noticed a clear difference from the Mundorf Supreme and S/O to Duelund VSF in tone and timbre and when the signal went through the Mundorf the Duelund did not sound like it can. (my crossover is through the mid range then to the tweeter caps)
Parts come in and they are not the right parts. Different output transformers. x101c and x101d are not the same I can see why one would get annoyed with this!!!! Both 7591 tubes but not the same transformers. x101d's are much larger!
Getting the x202 (Old Fisher) rebuilt and it needs a new filter electolytic capacitor.

I wanted my Tech guy to use ASC recommended by Tempo Electric as the best caps for that purpose anyone ever use them?

He was ordering Cornell and I never even hear that name in Audio talk.

Someone mentioned about old parts not being as good, better not talk to my Tech guy (an older English guy trained on tube gear but works more on TV's now) who thinks todays parts are by and large pathetic garbage. He says Electrolytic caps today are sometimes lasting only a year and in years past (as in the American made vintage gear) 50 years was quite normal.

I want him to replace anything that is needed in the old amp and he says only replace what is needed because every new part will be a down grade. (don't like the sound of that)

He feels this way about TV's as well thinking they have never been built poorer than right now and the best era was late 70's before all the U.S. manufacturing went offshore.

I have told him to stick to Tempo's list of just Tier A. Duelund (which I already know) V Cap and ASC if they fit.
Another question my tech guy said that in the past the transformers could look different but in fact be the same inside?

Is that right?
