lumin direct to "main in" section on Yamahas/Luxmans/Accuphase?

I have a Yamaha s3000 on loan from a friend, noticed some of these Japanese integrateds like to insert a "main in " section next to the pre-outs as well as two sets of binding posts to drive two speakers

I would like to connect my lumin d2 direct to this "main in" input and bypass the preamp section of the yamaha

worried about causing issues

can anybody confirm if this is safe to do?

It should be fine as the main in is basically a HT bypass that just turns the Yammy into an amp.  Just to be safe I’d start with the volume on both the Yamaha and the Lumin turned all the way down and go from there.  It’ll be interesting whether you prefer going direct vs. using the preamp in the integrated to be better.  Can be hit or miss.

Electrically that's fine.  The only issue is gain, so long as you have a volume control in your Lumin and you use it, no problem.

I have heard that there can be an impedance mis-match from these streamer "preamps" direct into a power amp. A proper preamp in between is preferred.

And if it were me I would look for a preamp with at least a tube buffer or a full tube preamp to warm up the sound. Or just stick with the integrated pre in.
