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!!!

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!

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.

When I first noticed that various high-end manufactures
uses Aromat/NAIS, I was quite surprised. I have had mucho
quality problems with them in (non-audio) instrumentation
applications. If you want to use an Aromat/NAIS relay, I'd
suggest the SX series (p/n's are ASX....). Just watch the
maximum current rating.

I suspect the bistabile relay is superior for those following the philosphie magnetic flux does harm the signals sonic quality. However, in this case we better should´nt transmit the signal electronically.

Else, read the datasheets behind the links above.

Bistable relays have permanent magnets inside. What is the differens between a permanent magnet and an elctro magnet?

OK, you want a reed relay recommendation. Mine is
Coto (www.cotorelay.com , I believe). I've use a number
of different types in precision instrumentation application
(DC as well as high dynamic range 100kHz AC). Very
good. If you want to get really fancy, look at mercury-
wetted reeds. Coto and most others are sensitive to
physical orientation (the Hg needs to stay in the proper
place), though Pickering (not my favorite relay vendor)
has a mercury-wetted low thermal EMF reed that claims
not to be sensitive to orientation.

Given my poor results with some Aromats in the past
few years, I'm avoiding them for all my work-related
applications. However, for DIY audio projects where
you could "buzz" them for a while and then verify goodness,
I'd consider an Aromat SX series.

Note that the SX series comes in normal as well as latching
(aka "bistable") configurations. You can get them
from Digi-Key.
