These capacitors can be plugged into the circuit either way. They have no orientation. I hope you enjoy them!

Norbert,
  Is this true for all capacitors or only for the Vishay? Thanks.

[dave_c]

Thanks NagysAudio!  I'll let you know how it turns out.  Hopefully I'll get a chance to do it this weekend.

It's true for all film type capacitors, metalized, polypropylene, paper in oil, etc. However, electrolytic capacitors usually have a positive and a negative.

Well just swapped out 3 Caps on my Trends TA 10.1 with Vishay MKT1822's and there is a difference.  The caps I swapped were the 2 input coupling caps with 2.2uF 100v and the Ca Bias cap with a .1 uF.  I'll reserve judgment until after they've broken in but here are a couple quick observations.

1. More dynamic and exciting sounding.
2. Treble is a little hotter. Not sure if its tipping things up or just less muffled but definitely more than the bennics. Might just need some break in.
3. Bass is a little bigger but a little less tight.
4. Soundstage a little wider.

I would say the treble and dynamics are the most notable effects. Again these are right off the bat so take it with a grain of salt. So far I like it better than the broken in Bennics.

BTW - These were my first mods ever on a piece of equipment and it was fun. Vishays are small and fit exactly in the holes without bending anything.

Dave,

I'll be following your observations closely because I have two of the Trend 10.1s which I want to mod. I'm currently awaiting delivery of some Obliggato OIP caps and will experiment with these first.

Look, I know enough to be dangerous. I sell electronic components to industrial and instrumentation manufacturers for a living and have been an audiophile and engineer "wannabe" for 35+ years.

Price aside, there are reasons why one would choose a certain type of cap over another. It is application specific. Do you need low ESR, low inductance, insensitivity to mechanical pressure (microphonic), temperature and humidity stability, low memory effect, small size, high current/voltage ....... yadda, yadda, yadda.  Just because a cap is good in one "socket" doesn't mean it will be better than another in a different "socket". There is no best for all cases!

There are measurable aspects to the performance of a component that help one decide what manufacturer's device to use in a specific application. To say that a lesser quality device sounds better is equivalent to saying that looking through colored glasses is more pleasing to the viewer. It may be true to the beholder but it is not more "truthfull".

....  and every person for every application with every combination of equipment has a different 'truth'.

Gurarantee you my OIMP's won't even come close on the bench to the same brand Teflons - but I wouldn't trade them for the world.

Hi, Could you PM me your DIY receipes for the speaker cacles and IC's? Thanks.

Hi Bill,

     I have used the Vishay MKT 1822 capacitors in dozens of different audio components. However, primarily I have used them in amplifier circuitry and speaker crossover. As I mentioned before, I love the Hiquphon OWII tweeter. I mostly use a second crossover filter with a 6.8uF capacitor and a 0.39mH inductor. Plus a zobel filter! A lot of people skip the zobel on the tweeter and it's a big mistake. So... in this set up I have tried plugging in countless different capacitors. All I can say is that between the Vishays and virtually all audiophile capacitors, there's a huge difference. Once I heard the MKT 1822s in the circuit, I could not go back to anything else.

I have also used them in amplifier circuitry. My main amplifier design is a dual jfet input, bipolar voltage stage and mosfet output. Since mosfets sound very similar to tubes (but better in most cases) I don't do too much tube amp design anymore. With this type of design I can achieve a very high slew rate and frequency bandwidth into the 1-2 MGz region. That to me sounds better than any other amplifier design that I have heard or used. Also, this type of design eliminates coupling capacitors, so I use the Vishays mostly as bypass components. Power supply bypass, high frequency and oscillation control, etc. And again, they sound fantastic!

Norbert

hello Norbert 
I want to change the capacitorses of coupling in my preamplifier phono solid state . 
I have read your thought on capacitor vishay MKT1822, I want to try in my phono. 
do I want to ask you a question, the MKT1822s I have to use alone, or is it better to make a bypass with other smaller capacitor? 
have you made some tests? which capacitor bypass do you recommend? 
thanks for your help.  you greet emiliano

dave_c, f-100 and Norbert,

re: orientation of film caps, I believe Dave's question was pertaining to which direction sounds best as opposed to directionality necessary for it to function ala polar electrolytics. As many here I'm sure know, there can be an observable difference in sound when the outer foil is oriented one way or another.

[NagysAudio]

tolvix, you should replace capacitors with exact identical value, if they were bypassed originally then you should too, if not, then don't bypass them.

all film/foil capacitors sound the same regardless of their orientation.

[Ric Schultz]

Film caps have an outer foil.  This outer foil should go toward the output or ground.  You can easily hear this on a tweak system.  This is important.  Many cap manufacturers put different colors wires on or mark the cap for outer foil.  Listen for yourself.  Don't believe anyone.  I listened, and now I know.

Bypassing is an art.  Listen to no one.  Listen for yourself.

Hi Rick,

Well, have you tried these 1822 caps he talks about. I'm thinking about getting a tube preamp. I wonder how they will do as coupling caps? I don't know the size of the various coupling caps on the preamps I am looking at. At least, not yet.

I've been into audio for 11 plus years and I have heard dozens of capacitors. Everything from military specd, to audiophile grade. Ranging in price from just a few pennies to hundreds of dollars.

And the best capacitors that I have ever heard are Vishay. These are made in Germany by Vishay Roederstein to be exact, model number MKT 1822. They were previously know as the ERO capacitors. The MKT1822 is a box style timing capacitor, made out of metalized polyester. They range from 1000pF - 15.0uF and have voltages from 63vdc - 250vdc.

Most audiophiles will disagree because it goes against all audiophile grade logic. They don't have Teflon, copper foil, silver foil, polypropylene/foil design, silver leads, oil, etc. But what they have is what counts, absolutely stunning sound.

It is virtually vale free and grain free. I have never heard any other capacitor come close! They have incredible resolution and sparkle to the high frequency. The term "liquid" should have been invented for these caps. Plus they have to most un-electric midrange I have ever heard. The best part is that they are dirt cheap, a few bucks max for the larger values. And they work as well in speaker crossovers as they do as coupling or bypass capacitors in amplifiers, preamps, dacs, etc. Here's a list of some capacitors which I compared the MKT 1822's to.

Hi, Do you happen to have 4 10uF caps? Don't want to get just four of them from Mouser. If so, just PM me. Thanks.

Well, I'll reply to myself, and ask about the coupling caps. The 1822 variants from Mouser, there is a 450V 1.0uF that I'll need for the coupling caps. Unfortunately, if I read right, you have to buy a lot of these caps at once. So if any one has these 1.0UF 450V caps, would be interested.

Also, on the electrolytic side, the power supply board uses 6 22uF and on the audio board, it uses 3 22uF and 1 1000UF at 25V. This is for the GGP from Transcendentsound. I thought I'd just try these caps and see how they work.

Hi Norbett,

Do you happen to have 1.0uF at 400V. Mouser has a minimum of 125 caps. I only need like four of them. These will be replacing the 1.0 coupling caps on my new GGp preamp. Now if anyone else has them, that would help too.

Ray

[NagysAudio]

Hi Ray,

     Sorry to reply so late, but I haven't been on here in a while. Busy with work. I don't have the capacitors you requested. Besides Mouser, they pop up on ebay periodically.
