Audio Relays in Pass Preamps

[timlein]

I am looking for high-quality audio switching relays (mechanical) for a preamp I am building. Does anyone know brand/model of relays used in Pass preamps? I figured they would use the best quality ones out there.

Anything with gold contacts and made from a reputable manufacturer would be fine.
Maybe something with a milspec certification to ensure reliability.

Zen Mod would know of specific suitable parts.

I think in their most expensive product they don’t use relays to do switching between inputs but use an individual preamp circuit connected directly to each rca connector.

Zen Mod wouldn't know ........ even if that's certainly visible from myriad of pics posted everywhere

though , nothing wrong with Fujitsu ones , Takamisawa RY series

regarding zillion of preamps , each input having own channel - that's simply not getting with practical and not-wasteful sense of Wayne's approach ...... at least as I see it

Panasonic’s always favorites, but they are leaving the business. Lots of good ones NEC, Zettler, Takamasawa etc.

Tokin is now apparently a relay company...

You bloody dumber bastard.

The problem: extensive listening tests revealed there was no method of switching among three pairs of inputs that did not degrade the sound, when compared to direct connections. Confronted with this challenge, Pass Labs’ design team decided that each of the Xs Phono three pairs of inputs had to have its own separate, directly connected stereo phono stage. There are no switches or relays in the signal paths to the hugely important first amplification stages.

ha!

who's dumb now!!?

that's exception , and most probably well reasoned one

nobody asked about MC switching ....

Phono still has a preamp.

We are dumb and dumber. I guess it depends on the day, who wins title of dumberer.

I am still bloody dumber.
Hahahaha

For very low level the Panasonic ASX relays are my favorite. Now replaced with the NEC EA2 series.
