Dave_cThese capacitors can be plugged into the circuit either way. They have no orientation. I hope you enjoy them!Norbert
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".
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
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.
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.AuriCapHovlandSCR SolenJensenRelCap Audio Cap ThetaMultiCap RTXMultiCap PPMFXRussian Military Teflon High Voltage Types

Don't want to get just four of them from Mouser. If so, just PM me. Thanks.Ray
