Quality RCA Switchbox


Does anyone know of a quality RCA switchbox that will accept several RCA stereo inputs and have one pair of RCA outputs so I can use several sources with a preamp with only 3 line level inputs?

Same question applies to digital sources; any digital switchboxes for coaxial sources that have a coaxial output so multiple coaxial digital sources can be routed to the single coaxial input of a DAC?

I was out touring Manley Labs (Chino, CA) a few months back, and EveAnna showed me a prototype of a very high quality RCA switchbox. You might contact her about whether it is available as yet.

Thanks all; am following up on DB Systems (already have a ten year old one) and with Mapletree. Their selector box looks useful.

I was looking at digital switching boxes. Best I came up with is a Midiman unit that retails for 250. It has multiple XLR/Toslink/Coaxial inputs and can convert any of these to one of the three digital formats for output. So, if anybody needs a decent digital switching box this one may be a candidate.

Anybody know of a quality digital switching box that will accept the three diff interfaces and convert them to XLR and/or coaxial other than the Midiman?
Jena Labs makes these to order, well built with high quality parts. A member here, Mike Lavigne uses one.
