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.

It is just my personal opinion but I think you are right to stick to copper foils for your amp of some kind. I read many stories of vintage amps going to poly of which Mundorf is and losing the tone. My own experience is you do best by bettering the same kind of part but of better quality. Meaning your amp was voiced on foil caps. Mundorf would be better than a lower grade poly if that was what was in an amp.

Now what is better about that famous amp you have? Different tubes, better caps?

I did just check out the Ampohms and it is quite interesting and for me I am not surprised they sound tonally better than Mundorf Silver in Oil. It is also interesting on the thread you posted I have read JonL thread before. The price sure is right. I just wonder about resonance? That is the downfall to foil caps keeping them from resonating.

I see another guy just got some Duelund VSF's. It will be interesting to see what he thinks. For me I know they are expensive but I have a bunch of other parts (that were not cheap) and were not better in every way than the vintage parts. Duelund is. I have no nostagia when using them!

Duelund you really need to get these caps into the recording studio. I am serious on this. We will for sure enter a new and even better "Golden Age" of recording than from the early '50's to mid '60's.

Jensen's new copper paper tube is interesting (for lower cost operation than Duelund) and I have one coming. I expect them to be better rated than the old Jensen's.

I am eager to hear what Jimmy finds out. I bet it is and I could look very silly in this prediction.

1. Duelund CAST (he will say a little tight when first new but extremely low resonance and very natural)
2. A close race from the Teflon and Jensen (paper tube type) (bet he says Teflon has a signature)
4. Mundorf Silver Gold Oil
5. Old Jensen as tonally rich but too noisy in comparison to these other fine caps.

What do you guys think something like that?

"Now what is better about that famous amp you have? Different tubes, better caps?" The Fisher? The huge output transformers, 55w per channel. Sounds best with Telefunkin 12AX7's, and GE EL34 fat bottles.

"Tempo Electric has changed their ratings based on what has been said here by many of us..."

I just want to de-lurk to belatedly clarify this point. We didn't actually change the ratings, themselves, but we did change the way the rating tiers were labeled.

Based on comments earlier in this thread, there was an implication that caps on Tier D were grossly inferior to the ones higher up, when they are really good enough for general use by the typical DIYer. Not everyone can spend the sort of money that Duelend or VCap Teflons, among others, cost, so the vast majority of users will probably find caps on this lower tier to be the most affordable for their projects.

To remove the possible stigma, we renamed the top three tiers AAA, AA, and A, respectably, since that's where the really outstanding performers ended up. We then changed the name of the fourth level from D to B. The differences among the first three tiers were often subtle and you really need to be at the outer fringes of perfectionist audio in both equipment and listening skills (I modestly include my partner, myself, and our listening panel in that category) to appreciate the improvements that these caps can provide. Generally speaking, you also need deeper pockets and a higher level of obsession than the typical DIYer may have, as well.

In addition, for the vast majority of listeners, the top tier caps may be financial overkill. If you can live with the trade-offs mentioned on Tier B (formerly Tier D), then it's possible to elevate mundane equipment to something far better without busting the bank.

A point which many DIYers may overlook, is that by carefully matching inexpensive caps that otherwise didn't fare so well when compared to the very best, it's still possible to achieve a sound that's surprisingly good. For example, in his personal phono stage, my audio partner, Dr. Arthur Loesch, paired the hard sounding Electrocube with the soft sounding Vitamin Q and achieved surprisingly good results. It's not the way I'd prefer to do it, but the sound was far better than the relatively low cost (or individual flaws) might suggest. In the production version of the same circuit, we had to spend 10 times as much to hear a 5% improvement (advancing from 95 to 100), but that's what perfectionist audio is all about.

As for the next round of comprehensive tests, Arthur and I are working on a set of aftermarket cross-overs for the Tannoy Monitor Gold drivers, so we will eventually revisit the speaker caps which were overlooked or unavailable earlier, including the Duelend CAST PIO series. We're also working on a couple of new electronic designs, where overlooked lower value brands will be compared with the best of the earlier rounds. Given the snail's pace at which things happen around here, this could easily be as long as a year from now (September, 2010).

For those who are curious, we agree that the Dueleund resistors are the best we've heard to date for use in loudspeaker x-overs (we rate Caddock MS and MV series as the next in line), but we're also interested in trying Intact Audio's (Dave Slagle's) latest type which are custom wound with copper magnet wire, based on the desired resistance at a given temperature.

Thanks! And now back to our regularly scheduled discussion thread...

Hi Joseph

I would like to say thanks very much for your site as it deals with a very important (to audio nuts) issue of the quality of passive parts.

I assume once someone is going to your site they understand that passive parts do matter and one can easily hear the difference.

This is were the tough part comes in. My two main sources of info were your site and Tony Gee's both excellent. I actually found your (wording and description) to more accurate (or to my ear IMO) in the the caps I heard. Your description was very good on Duelund VSF vs. Mundorf Supreme. Cost 6x as much but might be 2-3x better. I also agreed with you on the Silver in Oil as I thought it tilted the sound upward and left a signature on the sound which might be Ok if one was trying to do that? IMO I agree with your site, get the Supreme unless you are willing to spend the extra for Duelund. But if keeping the speakers Duelund well worth it. Good wording again and even as a Duelund fan I would not put them into a set of speakers I did not already really like and plan to keep.

Another tough part how does spending money on caps rate compared to all the other areas of ones system that could be improved and this will always be tough as you can not know what ones system is or how much they think the improvement is worth. As Dgarretson had mentioned long ago on the need for balance. I agree with him in principal except I believe the crossover is a area of MASSIVE weakness is most systems. (the after thought to most speaker companines)

When I had my Linn speakers I used $1k (here in Canada) worth of tri-wire (speaker wire) all hooked to a $2 tweeter capacitor and this IMO is a complete waste of money! Moving to $20 Mundorf Supreme tweeter cap would have been vastly better money spent. A bigger improvment for a fraction of the $. I suspect this pattern to be very wide spread. I would say 99.9% of people have NOT overspent on their crossover.

In Tony's site he rates 48 different caps. He gives 12 (was 13 before the downgrade to Mundorf Supreme)(or 25%) of the total a 10/10 or above. To me I found this confusing? I did not know why I would want better than a 10/10 cap? I thought they all must be awesome compared to what I had as they were all better than 10/10. Would I even hear the difference?

When I could hear the difference so easily from Duelund VSF to CAST I was shocked! My VSF was rated 12.5/10 wayyyy beyond perfect? I wish Tony would rate his top cap a 10/10 and downgrade all else from there. If Tony had a Duelund CAST at 10 a Mundorf Supreme at 6 and a Solen Fast Cap at 3 or so this would be very accurate to the reader. If I have 3's in my crossover (which I know signals failure grade) going to a Mundorf Supreme at 6 would be a significant step up which in my opinion it is and likely very good bang for the $ for almost anyone in any value of speaker.

As much as we (on this thread) are flattered that you changed the rating based on this thread I personally think your old ratings were better.

I admit to not ordering Tier D Jensen's based on your rating but this is not a bad thing thing. You likely have saved me money. Passive parts can be fantastic bang for the $ but it can get quite expensive to make sideways movements. I have come to the conclusion I am either have good hearing or am very fussy and your Tier A (maybe B) (old rating) is all I am looking at.

Joesph from your site and your accurate description's is why I ordered ASC power supply caps as I wanted to hear what does a power supply do and what is it's relative value compared to crossover parts? (not yet done with this one as there were other issues)

I say stick to your guns and keep the old ratings. Let the cookies crumble were they may. Maybe it was your rating that forced Jensen into a new cap? A person not really in to this will be Ok anyway with Tier D. The letter grade will not upset them. A person who does care will get a false sense with Mundorf Supreme being rated Tier AA when it is a good cap but Tier B sounds much more realistic.

More than you raising your ratings I really hope Tony lowers his ratings to only one cap being 10/10 after all there can only be one best anything setting the standard.
