Probably should have said a bluetooth module. Lots on Ebay but most have a built in amp.

I must confess. I accused the korg B1 of being bright.

I originally went with a Mylar coupling caps (wima mks 6.2uf). It was a little bright. Not bright, but uneasy and etched in the top end. I tried Silmics bypassed with the Mylar. Not good. I tried a combo of silmics, Mylar and .1uf polypropylene. Not any better.

So I bought 6 clarity cap esa caps...6.2uf. But guess what? There is no way they are gonna fit in my chassis. In fact, the 6 of them would take up my whole chassis.

So I decided to give up. I put in 100uf silmics bypassed with a generic .1uf polypropylene cap and left the Mylar wima out and put it back together.

And remarkably, this seems to sound spot on perfect. Not etched, bass is good. What the hell ? I have two other preamps on hand for comparison, so it’s not placebo. Old albums like pet sounds and early 60s stuff doesn’t sound thin and etched anymore.

I have installed Cornell PP cap replacements, along with Vishay PP to replace the third caps. This has made a nice improvement. Thanks to Claude for recommending this. Installing them was a nightmare due to cap sizes - I will find a more elegant solution to hold all these caps in place. For now they are propped up with non-audiophile blu tac.

Unless I'm mistaken, Papa's two favorite electrolytics in the signal chain are Elna Silmic II and Nichicon UES green bipolars. I've tried them both and can't really tell the difference.

My thinking has always been Polypro>Mylar>Electolytic in regards to sound quality. But apparently, this is not always the case. I will throw away the mylar caps so they shall never be used again.

Audio note makes some fancy electrolytics called "Kaisei". Not cheap but I might try those. The 6.2UF Poly caps I bought that were too big will go in the PSU of my power amp...replacing the mylar that's in there.

I have tried WIMA MKS several times; I never liked their "sound".
"Uneasy and etched" is actually a description I could subscribe to as well ...

I'm very happy with WIMA MKP's, though (MKP10 / MKP4 / MKP2).

In electrolytics, I had good experience with ELNA Silmic II and Nichicon UES, as well.
My favourite electrolytics in larger capacitances are still Panasonic FC ...


Best regards, Claas

Witch's oils of caps are mysterious. The ubiquitous mitsubishi logo'd poly orange drop types I used worked a charm.

Electrolytics with polypro bypasses also seem to work well.
