NAD M3 Master Series Amp

Yes there is. Niles makes a couple of products that will do just what you want.

I believe that there is a factory provided firmware upgrade for the NAD M3 which converts one of the existing inputs into a HT bypass. Contact NAD directly or your NAD dealer for details on how this can be done.

If true, that would be awesome.

You can set up your M3 to simulate HT bypass. Just plug your L/R from the Onkyo into any line level input and then set the volume level of the M3 to a reproducible setting that matches the Onkyo volume levels. You will probably have to play with both the M3 volumn control and the Onkyo volume adjusts, but once set all you have to do is set the M3 to the reproducible volume setting when you want to do HT. I think the M3 has a digital volume readout, so setting the volume reproducible should be easy.

Thanks for the replies folks. The Niles switch is something I don't want to use, I don't like anything inline with my expensive speaker cables.

Also, I've tried using the L/R outputs from the receiver into the M3 but I had to have the M3 volume up to max just to get enough volume to match the other speakers. That just scares me knowing that some day, I'll forget that the volume is MAX and blow up something. The M3 is so quiet, you can't tell it's up to max, and the display is so small, it's not obvious from my listening seat.

The solution would be having the firmware upgrade and that's what I heard would do it but nobody, including the Master Series Dealer knows anything about it.

Stevizzy, since your dealer is unaware of the firmware upgrade I suggest that you contact NAD customer support. They are certainly aware of it since I know of someone that previously had it done with their support. Good luck!

Thanks guys for all the replies. Today I called Bob Moran at NAD Canada. He got me setup with a service center in Baltimore that's going to run the firmware update for me. He said it's something I could do with a Windows PC and sent me the codes, but I'm a Mac user and would rather not fuss with it. It's not difficult but if not done correctly could be tough to correct later.

They are a great Company to deal with. He made sure everything was arranged and that the service center had the proper firmware codes. They couldn't have been more helpful. Best experience I've ever had dealing with an audio equipment manufacturer. They really care about their customers and the equipment they sell.

Glad to hear that NAD is handling everything for you, and Bob is definitely the best person there to work with!
