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.

Had some other issues when I re-worked the XO. Everything has opened up now. The CAST are WAYYYY quieter than the Solens that were in my Maggy 3.6s. I'm with you Volleyguy, I might prefer a little bit "juicy" noise for some airiness. The quiet blackness is positively frightening. Someone remind me how long these caps take to break in as I'm only at about 80 hours. Oh, I love the V-cap CuTFs as an inline electronic blocking cap versus the TFTFs. Very, very natural. Once you've heard them you won't want the tin foil version.

The CAST did take a couple of weeks for sure. One thing that will be left in someone's mind after hearing the CAST is just how much noise is in the average crossover. Like I have said on here before I just can not take a speaker seriously that has caps like Solen.

We are just getting to finishing the basement now. Will be done in a month. We a had (small) leak a year ago and has not leaked since, nor before for 15 years! Looking forward to some final tweaking.

The downside to CAST is at first they are shocking. After awhile everything else is just noisy. In this thread when I first got CAST from VSF in the tweeter I really wondered if I would even hear the difference? I was blown away! So much for diminishing returns.

CAST made me realize just how much noise we are subject to everyday.

Could you imagine what recorded music could sound like if the recording side used CAST?

I think Barry our mind has an idea of what the music sounded like live. I do not think CAST add a thing to the sound. VSF do. I choose a combination in the tweeter and money was not the reason.

Do you think Natural describes CUft? Neutral would be it for me.

That juicy "noise" can be had in the VSF. So much CAST talk but I love Duelund's VSF. They resonate very naturally. I do wish I got (or could hear) a CAST woofer inductor. It was shocking how much noise was cut by that part and a CAST I bet would cut much more noise.
Every step for me John.

I took criticism for doing it that way but kept one network stock and one with each new part. Duelund used to laugh because I would order 1 cap at a time. EVERY Duelund part was an improvement to me accept the tweeter inductor and in my mind it should be said once you change resistance all bets are off if it will sound better.

I did it that way for the vary reason to not be duped into I spent a pile so it should be better. If you remember at the beginning I put in one network of Sonicaps had my wife hear blind and she went Wow! That is wayyyy better. She was talking about the vintage foil caps!

In that case I have one Duelund tweeter inductor not used.
So have about 550 hours on all the Duelund parts in the new tweeter/midrange XO of magnepan 3.6Rs. Very neutral, quiet, extended & refined. May go back to the stock XO and do a comparison over the coming weeks. Aural memory's far from perfect but for all it's shortcomings, and it had several, the stock XO seemed to have a bit more presence and was just a bit more exciting. It's an impossible comparison (VCaps in electronics; Duelund in an XO) but I will say it anyway, the VCap CuTF is a touch warmer/sweeter in the upper mid, lower treble than the Duelund Cast. The Cast reminds me of the VCap TFTF - a great cap but just a bit cool sounding.
