One cdp into two amps


I have recently acquired a wonderful Rega Apollo that I would like to use as the source for two different systems set up in the same room. The Apollo has a digital coax out that I could connect to the solid state integrated amp and also analoge RCAs that I could connect to the tube integrated amp.

My question: Is this potentially harmful to any of the components?

Clos,

Unless you integrated amp has a DAC built into it, you can not use the digital coax connection.

Most integrated amps do not have DACs in them. Typically an integrated amp will require and analog input via either RCA or XLR(balanced) connection.

However, if your integrated can actually accept the digital coax connection, you can always safely connect the digital output and the analog output from your player to two systems. I think the only potential issue is that it could possibly cause a ground loop hum depending on your electrical connections.

I've used your suggested connection method many times in the past and I have not experienced any issues.

Enjoy,

This is good news since the solid state (Nakamichi IA-1z) integrated apparently has an onboard DAC (I could alway refer to the Nak's manual) since I am currently running a digital coax from the Apollo's digital out and it is definitly working and sounds great.

If this is the case, it is simple enough to test it. Simply connect a pair of RCA interconnects from the analog outputs of the Apollo and into an open RCA input on the integrated amp. Switch back and forth between the analog connection and the digital connection while playing a CD. If it works, you know both outputs are active at the same time (I've never know a CD player that didn't have both active at the same time, but I haven't owned ever CD player in existence).

If the test proves that both are active, there won't be any issue with having the player connected to two systems. I've done it many times with many different CD/DVD players and amplifiers/receiver.

I guess it is possible that it could create a ground loop hum. If you do happen to cause a ground loop hum, look here in the archives for solutions.

Enjoy,
