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.

Hi Again.

First thing to take in consideration. The RIAA which is equipped with V-cap is better and a lot improved compared to the Clarity unit.
The Clarity MR has now 6-7 Hours , The V-Capped has about 60 Hours.
We are using a pair of Telefunken ECC803SS and they are properly some of the best ecc83 series tubes money can buy.
I know that this is a little early to write about anything but it's a lot of fun to listen to the performance dying the burn in period.
Both units sound very accurate , but the V-cap is a lot ahead at this early state but the Clarity isn't bad at all.

I own the Clarity equipped RIAA and the Telefunkens , so i'll be able to post about Clarity , but just to be fair these to caps are absolute not in the same league. But for sure the Clarity MR , had make me dust of my Micro Seiki RX-2000 and i have started to enjoy analogue again.

Have been following this thread for many months. Just installed Duelund cast caps and inductors in the tweeter midrange section of the XO of my Magnepan 3.6s. Cost a small fortune. Treble's more than a bit recessed so I'm hoping everything opens up a lot more. Will read the thread again but does the treble open up and begin to sparkle as the caps break in? The cap in series with the tweeter isd a big one-- 17uF, so I'm sure it's going to take a while. Mid-range sounds a bit clearer with the Cast inductors. Has anyone measured the series resistance of Deulund 12 ga caps? How do they compare with more standard values and caps like the stock Solens?
Hello,

I have a pair of SC-VI (160A and 160B) and would like to upgrade the crossover, perhaps with Duelund resistors and caps, and maybe bi-amp using an active crossover like the Krell KBX.

Does anybody have the SC-VI crossover schematics, or at least crossover frequencies?

Thanks!
Hello Barrysandy

That was the idea of this thread to give opinions of sound of caps. The CAST caps are low noise or recessed. I was shocked by them and that was coming from even VSF. VSF are clearly noisy in comparison. That being said I have a CAST followed by a VSF in series. I compared two CAST vs. two VSF and then one of each. A little noise can give a little life.

There is no doubt which is the best cap.
