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.

Cap order is in for 13uf VSF Duelund. I am like my kids in counting the sleeps!

Stormen I will need two more caps for tweeters and am looking at the CAST ones for the tweeters. I am very curious? I will be only using one CAST a side (but I am going to test two to see the difference) as I own the VSF's already. Is that where you would put the money in the first place would be in the tweeter as that is the toughest to get right?

Duelund makes custom orders like the 13uf I am getting and the price is just the cap value price.

Kind of itching to get on with this and order the rest of the parts. But the Duelund is not cheap so I do want to make sure it gives the improvement in the midrange that they do in the tweeters.

Only question is will I do the inductors? The vintage caps were worn out no doubt so the improvement is HUGE but the inductors do not wear so it is only a quality improvement.

After the mid cap and if all goes well I will order 2 CAST tweeter caps and the other mid cap and be done for now.

I can not even comprehend the CAST caps? The VSF's exceeded my wildest expectations and can not understand the improvement on them?

I will do much more burn in on the Mundorf's. They are around 50hrs and will burn them into several hundred as I am curious to how they eventually settle. I also want to know for future use in possibly replacing the caps in my other speakers. They may be more cost effective as I am unsure how much $ I would want to spend on them.

Right now the Duelund's make my other speakers unlistenable. So that is the downside that one may want to consider, the speakers you thought OK will sound awful after Duelund becomes your reference.

It would be relatively inexpensive to try Alphacore air-core foil inductors. Cannot be certain, but it's likely that the sonic difference between ACore and your stock inductors is greater than the difference between ACore and D inductors. ACore sound really good. I believe they also make them in silver. What does Chris at PcX say, as he carries both manufacturers?

As someone mentioned above, alternative tweets might be the best spend.

Dgarretson

I have talked to Chris about this as Alpha Core was top on my list.

He did say they sell many more D caps than inductors. I can not comment on the Alpha Core compared to vintage. In my mind one would want to spend more on tweeter caps than woofer inductors as the high freq is so much harder to get right.

Stormen where are you? Stormen did say the difference was big in inductors. The Duelund is certainly much better built as it is CAST and has zero vibration.

I do hear where you are coming from dgarretson. I remember reading somewhere in some Linn writings about vinyl and the stylus and how much tougher it was to pick up say a violin freq compared to a bass freq. The magnitude was shocking! It lead you to believe that you could error much more on the low freq than high.

So my next $ after mid caps are to try the CAST tweeter caps. If all goes well I may just buy the CAST inductor more out of repect to Duelund (for what they have done to my system) than any real gain coming. (compared to Alpha Core)

I can say the Duelund's have made my other speakers unlistenable. I am ticked in that sense that I wanted a system for the livingroom (and got one) as my Klipsch will never get there (they are in the basement) as my wife hates the looks of them. (can't blame her)

I am a LP12 fan and was planning on getting a Trampolin II maybe next and did believe the Linn theory that source is the most important.

I now have moved any Linn upgrades down below new caps for the Linn speakers. I also have doubts on Linn's cost effective Aktiv upgrades. I know they work. They do electronic crossover and remove the passive ones. I am just wondering if say Mundorf Supreme caps could do the same thing for wayyyyy less cost then two more expensive amps and crossovers?

I have moved into Steen's line of thinking. I have been there actually for awhile. (as I enjoy my Klipsch with vintage tube amp and fairly cheap CD player better than the better source better pre and better amp as the speakers seem the weak link) Linn's theory is good source cheap speakers beats poorer source better speakers. I do not know if I agree with that anymore. (well I know I don't)

Steen's with 50% of the system being the speakers. (Johnk you have to like that!) Steen saying that 50% of the speaker should be the crossover just upsets people!

So Dgarretson you may be right that AlphaCore inductors might be almost as good? But should we treat crossovers so lightly in this hobby? or is Steen right? I know you guys have not heard it and can be skeptical but I know I will never treat crossover (and caps) as some non important issue. In my mind the crossover has moved wayyyy up in importance.
