I like WIMA MKP10 ... have used them in all my preamps, also in M2.

Best regards, Claas

I can also recommend Clarity Caps and yes they are better as you go up the price scale...
Best bargain are Russian PIO, that is what I used in my BA3 as Preamp :-)

John, any specifics with the Russian PIO? I've read anecdotal things about the ones with "Ch" suffix are better suited to AC and have better frequency characteristics (for whatever that really means), and the "KBG" ones have been described as having aluminum foil - paper - aluminum foil - paper layered construction. The rest seem to be more generically described as "sputtered/metalized" ...

Eric, I’m most fond of the sound from the rectangular can variety. The letters are not available on my key board. They are sometimes called MBGO. You won’t need high voltage ones. I used the 160 volt rated. I do give the sonic edge to the 630 volt rated variety but they get very big very fast - just pick a well liked seller from that famous web site :-)

Do note that often you need to isolate the shell of these metal can pio from the chassis and ground :-)

I user Janzen Audio Silver Z. Not cheap, but supposed to be premium quality. A bit too big for the boards but could manage to fit them.

I had to build a brace work to hold my 10uF caps above the board. Unless you lead wires are quite long, remote mount of large caps is a viable option.
