Reddit mentions of Logitech Harmony 350 – Simple-to-Set-up Universal Media Remote for 8 Devices

To complicated and confusing. Can you cut to the chase?

You knocked something into something ... then what happened?

"I accidentally kick the hi-fi and knocked it onto the tuner." ...and then ...what?

So, what is it you need? Seemingly a remote, but what happened to the existing remote?

The remote had a AUX/MD switch, but what is MD?

You CAN NOT run the speakers directly from the Computer.

If you want a full universal remote, nothing beats the Logitech Harmony Remotes. Harmony has many thousands of devices that they support, and you can check them in advance on-line to be sure your device is supported.

I use the Harmony 350 with Rotel, Onkyo, Yamaha Stereos with out any problem or conflict.

You plug the Remote into a computer USB input, the go to MyHarmony.com, enter your equipment, it is automatically programmed through the USB connection. No messing with codes or pushing the On/Off button 50 times.

Now if you want to replace your amp, then consider what features you need and how much money you want to spend. You can get a very good very reasonably price Amp w/DAC and decent power for a pretty reasonable price -

There are many of these Class-D/Class-T amps available on Amazon, the prices range from about $25 up to about $150 depending on brand, power, and features.

I'm still not sure what the problem is or what you need, but hopefully I've given you some options to consider.

Harmony 350 works fine. It might not have a fancy screen on it or anything but it will control just about anything.

Unless the TV remote has multi device capability you're stuck. I would consider a good universal like a Harmony 350 $35. Program it with your TV, stereo and cable and you should be good. Have the volume effect the receiver not the tv and you're in business. The web control makes it very easy to program the unit.

I second the Harmony Remote. I have had 4 or 5 over the years (currently using a Harmony 700 and Harmony 650) and all have worked REALLY well. No problems with my Roku2 XS or my Roku 3 with them. It controls my TV, my soundbar, my xbox, my air conditioner, etc!

Note the Harmony 350 (which I have NO experience with but should be the same as any of the other harmony remotes, minus the screen, as far as I know) is only $39 at Amazon:

ah ok didn't realize there was a passive version, those do look pretty nice!
 
Since you already bought the Q5 and the remote seems like an important feature to you, i must say that the included remote is kinda chintzy, generic device thing that needs much better aiming than a usual TV remote does. however the Logitech Harmony line of remotes does work with the Q5.
