J.Rowland Is it possible to shut off the display

And Concerto is also AMAZING!
So, is it OK to leave amp always on?

again, I haven't used the Concerto, but the Concentra is designed to be left on all of the time, and I would guess that it is the same for yours.

Why would you deactivate the balance control? It's one of the amp's most useful features.

As I recall, from owning a Concentra II in the past, a chip has to be changed inside the unit to make the display turn off after 5 seconds; JRDG can provide you with the chip and intstructions on how to do it. JRDG gear is designed to be left on all the time, hence no on/off swith on the front.

Really? How so? To compensate for bad recordings, or limitations in your listening space? I use a balance control in my car, in order to compensate for the unfortunate listening position, but a home system? Please enlighten me.
