I have for sale 4 pieces 0,47uf verry little used top pio caps from Ampohm.They are in like new condition.Leads are about 40mm long.This caps are truly top notch in sound,verry transparent,musical and never harsh.The sound is so smooth and just musical.Plese look online for positive tests.They are way betther than many other modern PP and Pio caps.For verry little price you have a chance to have truly verry good sound.Price is 60 euro for all 4 plus shipping.

AmpOhm Tin Foil Paper In Oil Capacitor
If you have been following this thread, you may know that I have been enjoying the venerable Mundorf Silver In Oil more and more of late. After everything has been said and done, when I actually had to choose ( 😱) one capacitor for my amp to do some actual music-enjoying, I somehow chose the Mundorf SIO. No, it doesn't "seem" to have 100% of good Teflon caps' transparency and resolution, and it doesn't quite have 100% of the weight and bloom of a good paper-in-oil; but it has enough of those qualities while avoiding to sound too literal (e.g. some Teflons) or too rich (e.g. some PIO's). So it came to me as a pleasant surprise when the AmpOhm Tin PIO directly replaced Mundorf SIO and seemed to be sounding at least as good! From experience, I knew oil caps need to settle in the specific circuit through regular use, so I let AmpOhm play/turn-off for many days.
AmpOhm really seems to hit the right balance among PIO's. In some circuits, the wonderful Jensen copper PIO can sometimes sound a bit too refined and buttery for my tastes, but AmpOhm avoids that while still remaining smooth. Speaking of smooth, AmpOhm is smoother than the Russian K40y, which in comparison can seem to have slightly more prominent grain-structure. Mundorf SIO is not paper-in-oil, and as such, it has more top-end "air" and speed compared to most true PIO's. AmpOhm does not necessarily make you notice that extra air and sparkle up top, but it's still very extended when one listens for acoustic instruments like bells and triangles. What it has over Mundorf is higher density of tone and richness while not sounding syrupy or slow.
I still remember the first time I played Bach Cello Suites via AmpOhm. The cello sounded so magnificent I almost fell off my chair! Every detail, texture came through with power and vigor. They are much larger than similar-value Mundorf SIO, so make sure you have enough space, but they are very well-built, look beautiful, and sound even better. One caution. If you are looking to PIO's as sort of a filter to hide system faults by rounding, glossing-over, or rolling-off, these AmpOhms are not the way to go because they are still incredibly detailed and revealing of the signal chain.
