state of the art relays
 
Hi!

I want to make a high end preamp and i want to use relays for input switching and volume control. So i want to know which relay is the best for audio purpose?

Are reed relays better than other ones? Can I use cheapest ones I get, or are there differences? If yes, which do you recommend?

What are about HF-Relays which are designed for very high frequency? Are the good for audio signals? For example the Omron G6Y-1?

Please give me some recommendations. And please give me exact type names.

I have searched the forum, but have not found concrete information. So please help me, i am searching for THE best relay you can buy...

Thanks very much for your help!!!

For the input selector the best solution is to use
bistabile relay switcher.
relay:
Siemens V23042-B2203-B101
I think that this relays are gold plated...
And you need a digital trigger circuit to drive the relays...

You could ask Dieter Wochnik, he had very good Meisei relays for small money, his adress you can find on my relay volume control homepage: http://home.tu-clausthal.de/~tpa/relais/index.html

alternatively schuro.de has signal switching relays.

What is the advantage of the bistabile relay? Is this Siemens relay really one of the best relays for audio purpose? If yes, could you explain me why?

Does someone know some other very good relays? Have someone answers to my other questions?

Thanks for all your help!

You need relays wich closes with very low Imin of the signal switched.

I suspect you are able to read german: http://www.schuro.de/preisl-relais.htm

One of ther best relays comes from SDS which has changed it's name to NAIS.

The DS type is really good at very low currents. I had a bunch of those but not any longer.

No longer...
 
True, because I've got them now...

Do you have any of them "in duty" or are them still in the original box?

Here's the close up of relays used in top of the line Madrigal preamp ML32 and a link to a similar thread: http://www.diyaudio.com/forums/showt...129&highlight=
