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.

Fas948 I hear that too many VCaps will leave a signature. Any feeling on that? Some say cool?

Fas948 nice to hear that you agree with the CAST I thought Tony should have rated them higher than 13.5 because to me they were almost as big a jump from vintage foil to VSF as from VSF to CAST. I was dumbfounded.

Fiddler I am glad the Vcaps were a big jump over the Mundorfs. Arthur Salvatore thinks they are the biggest thing to come out in Audio in the last decade. (he has not heard the Duelund's to compare)

No doubt CAST are amazing as I have one speaker on CAST tweeter caps (right now) and one on VSF and I could justify in my mind upgrading to the CAST but must admit to still really enjoying one VSF and one CAST in the tweeters. I have heard that you get most of the benifet of the better cap in the circuit even at small values. I have 2 equal ones in series and have of course no way to test how one CAST and one VSF sounds in comparison to two CAST's.

The V Caps do seem to fit well (for me) and as far as prices and not even in the same league. $40 a piece at 5 or more. Duelund VSF $219 and CAST do not even come in such small values but start at $300++.

In small values V Cap prices really drop Duelund's do not. at 2uf like my tweeter caps VCaps are $322 each vs $180 for VSF and $361 for CAST.

Volleyguy, I have not experienced that on my Sony SCD-1, I use four on the balanced output stage.

I fully agreed that the CAST are a big jump from the VSF, a huge jump from many other caps.

Cheers,

Dear volley guy, I have the Klipsch KLF-20 speakers and have ordered the Duelund VSF caps for the midrange horn and also for the tweeter, along with the Duelund resistors. What capacitors have you tried on the woofer circuit?
Have you tried Duelund hookup wire from the crossover to the individual speaker drivers?
Have you tried different speaker terminals or are you using the original Klipsch terminal strips?

Hi David

There is no capacitor on the woofer circuit on vintage horn Klipsch. There is an inductor which I have not yet changed.

I have not tried Duelund hook up wire and the caps are still connected with Aligator clips. That is all going to change within a month. I wanted to really hear the difference and wanted another CAST vs. VSF test. I will go to upgraded terminal connections as well when everything is hard wired in. I do agree with Dgarretson that hitting many areas of weakness likely the way to go. It is where to spend limited $ I am sure duelund hook up wire is great but as big a jump as same $ on new coupling caps? or better tubes or going from VSF to CAST for tweeter caps etc? Fun hobby but trying to spend wisely can be tough but it is nice to know the kind of difference caps can make.

I have the 4 Fisher tube amps that I am testing and if that does not work will try another model. The x101d was so quiet I could hear around an instruement! Amazing! Unfortunately the other Fishers are not so good. I have a new output transformer coming to repair that amp. I have a x202 (uses 6BQ5 tubes) being repaired and may try a 400c with a power amp as well. Then I am going to mod one of the amps. My tech guy is slow! I have called and want to get this done. Itching to try out these Vcap Teflons or Duelund in electronics.

Nothing better than a fine tube amp, the perfection of Duelunds, and Klipsch horns.
Have you changed any of the inductors such as the North Creek 8 guage? Check out Krell_Man system here at AudiogoN. Very nice Duelund eye candy.
Wishing the best in sound.
