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.

Folks may recall that I've been rolling any number of caps thru a custom RK-34 pre, & line conditioners for a while. I've taken the pre and it's variations out of the loop and am only rolling in the conditioners at this time.

Mundorf SGO, Dueland Cast, CuTf V-cap, & the new Jupiter coppers, filtering/conditioning each system components. So 4 conditioner sections fed via 3 isolated lines from a sub panel. 1 leg is split into 2. one with a common mode choke & one w/out that feeds my amp, a Yamaha A-S2000. The other two individual legs go one each to dac, a Modwright Transporter, & the other to a Mac mini & g-raid which feed the transporter via ethernet.

I've shuffled these things around an awful lot and lived with the various caps feeding the different components so I thought some may derive some
value as I am satisfied I've a handle on how they interact in my rig.

First, I like the CuTf V-caps feeding my amp. They do take a long, long, time to break in, but they r fast, musical, detailed, and consistent. They don't vary in performance the way an oil cap does when in a demanding position. I can't say for sure, but I think that those teflon caps maintain their character when under duress better than other materials. I like em where there is high heat/ current draw. They pass what they r fed, not adding color or tone of their own.

I do like the oil caps, both Dueland & Mundorf SGO breath life & dimensionality (like tubes) into audio reproduction. I would not want to do without 'some' so... I prefer the Duelands on the Transporter/dac. Matched up with the right tubes and power cords it is 'just right'. Oils do great tone, body. vocals. The Transporter has a class A tube output stage, but so far the Duelands don't seem to 'shape shift' under duress or prolonged use.

The SGO filter the power for blueray, Apple TV, direct tv receiver, & a plasma tv. I like this cap. They do so much well & for a long time I bypassed em w/ the CuTfs. Ultimately they r a tad highlighted, but I still like em. My first 'oil'.... & quite frankly an excellent cap. Musical & enjoyable on the digital, i think they changed a bit when stressed by the amp section. I've all the caps in .22 values, but also a pr. of 3.3s in the SGO. With the larger cap it is possible to hear the 'shape shift' during a long session with the amp playing at relatively high volumes.

The Jupiters filter my Mac mini & my music library on the hard disk. For those who haven't tried conditioning their 'source' material it makes as
much of a difference as conditioning any other component. The speed & detail retrieval r superb and I don't believe current draw/heat is an issue on the computer/source. They seem as fast as the V-caps, a touch less body than Dueland, but very evenhanded. They demonstrate plenty of leading edge attack and extension. I like to think the Duelands on the dac just flesh it out a bit, adding a bit of meat on the bones in the same way a 6sn7 does vs a DR Russian supertube in the transporter. The V-Caps in comparison 'are not a tube'.

The overall effect is great! Open, spacious, musical, detailed, even handed, life-like, extended @ both ends, fleshed out from within so it's easy to follow musical details & fun to listen too! A great balance! The copper foil caps bring musical goodness to the proceedings. (The SGO
may not be coppers but I still enjoy em, they r simply highlighted a bit, tin foil?).

Perhaps focusing on a single cap would be better, but I'm not to sure...
Getting the right cap in the right place seems critical as I've moved these around and getting everything to fall into place was much more hard work than dumb luck. Tearing apart the way ones rig is put together for the hundredth time borders on obsession, but ....

Damn this sounds good.

CuTf do take forever, even longer to breakin. Initially they r dense and tight, very 'robust' sounding, & until you get it right may seem too 'literal', but with time, they r very good. They've got 'balls'...

The Jupiters break in much faster. Not as dense, perhaps? Would they
hold up under duress as well as the teflons? Not sure, maybe the relative lightness would be an asset, less material to 'distort', under high temp/stress. Wax being wax, like oil could be subject to the effects of heat/stress, but I can't say for sure.

I like the oils, on source. They sound a bit slower on amps in comparison which may suit some music but I noted several instances when the nature of a larger value oil cap 'changed' as a listening session went on. They seem to loose a bit of focus and you find yourself twisting the volume knob in search of more dynamic contrast.

Great caps in the wrong position have subtle but profound effects, perhaps that Hammond B-3 doesn't sound 'quite' real in dynamics or tone. The musical flow, it's timing, PRAT, can be just a touch off, artificial.

These guys don't design caps in a vacuum, more likely they are familiar with one another's and may even design to fit accordingly.

The copper foils all seem to share a common musicality with some variation in presentation.

Regards...
Hi Bigkidz and Regismc,
Thanks for sharing your extensive observations. I don't doubt for a moment that one capacitor may be preferable to another depending on needs and application. There's no perfect product that satisfies everyone under any and all circumstances.
Charles,
Regismc, thank you. Much better than my experience. You probably wore out a soldering iron doing this! Even with my limited experience, if you don't have the other cap to compare, you will be fine as long as you are enjoying what you are hearing, that is really all that matters. I really don't hear big improvements with specific parts, just different takes on what each does. You have to select what you prefer. Your filtering is way past what I have done in my system. I mostly focus on the power supply section for each component most pre and power components using choke and caps to filter the AC with great results. I also use tube regulation that has really reduced to noise to unmeasurable readings. I am now building separate power supply sections for the preamp and DAC. I want to try using Plitron transformers but the cost has held me up. I like to hear something before I try it out. Getting the noise level out is the key to a blacker background, space, air, separation, reducing hardness and adding dimension from my experience.

Anyway, no one in the NYC area?

Happy Listening.

Has anyone compared Path brand resistors to Duelund CAST in crossovers? I need two 1 ohm resistors on my tweeter and want the most natural sounding of the two. The one with no hint of brightness, hardness, or glare. Yes....needs to be resolving.

I have always used Mills MRA in past mods, but want to try one of these two.
No Bill, I have always used Mills also. Let me know if you ever get the chance to compare.
