Anyone know where I can buy a cross feed filter like the Corda Cross-1?

I bought one from Corda years ago, but now they do not list them.

thanks in advance

I got one on ebay a long time ago to try out, a DIY'd one. Sounded like crap. Given the state of my system now, the idea of putting something like that in the signal path is horrifying to me. The whole point of my system now is 100% separation of left and right from audio file to headphone drivers. It's possible that a well implemented crossfeed like the Corda ones can enhance lower-end systems, but there aren't any for sale unless you find a used one or a DIY'd one.

The Corda Cross actually has a lot of settings you can adjust. For certain amp/headphone/recordings it makes the music more enjoyable for me. the nice thing is you can always turn the circuit off.

It is a must for me with the Audio GD Compass and the SA5K headphones.

DIY Crossfeed kit

If you are handy with a soldering iron, there is a pretty good kit you can get to build your own, based on a modified Linkwitz design: Modified Linkwitz Crossfeed PCB

I just recently built one as I was looking into a way to reduce listening fatigue I was sometimes getting. The Tangent kit comes with a nicely made PCB and the necessary resisters and caps. The design includes a bypass switch, and 2 crossfeed levels. It's a high Z design meant to be placed between the source and your amp. And it's small enough to fit nicely into a Altoids can.

Overall think it helps alot and I use it more often than not. Since I started using it my impressions:
- the change is more subtle than I thought it would be, but it definitely does help reduce listending fatigue especially for listening to more detailed or channel separated material
- it increases the soundstage which is nice
- I like the low crossfeed level best, it's a better compromise between crossfeed amount and an alteration of the sound mainly at the high end which is evident with the higher level of crossfeed.
- It will reduce the gain of your amp some , but for my Little Dot amp that was not an issue.

Overall a cool project to try out. And as Spartan said if you dont like it you can use the bypass switch or quickly remove it from the path alltogether.

x2 on the SA5K. Listening Jazz, its like your in a huge concert hall and the sax is right at one end and the piano is at the other.

Jan Meier posted the schematic for the Cross-1. I have a hobbyist-built version of it, and consider it invaluable; most stereo productions sound unnatural without it.

I'd also recommend building or commissioning the Cross-I.

I don't mind a little mingling of left and right. You don't get strict separation in a concert hall. Insisting on separation makes things sound artificial.

Heck, I also like speakers that radiate front and back, adding room reflections. After all, if you had a jazz combo in your listening room, their sound would be reflecting off the walls, too. That might go against some concept of "purity," but damned if it doesn't sound closer to the real thing.

Living in Sydney there aren't DIYers to commission. I kinda wish Meier still sold them.
