Anyone know of a budget Integrated Amplifier that has a mono switch and balance control. For example I have a speaker outside and to a downstairs bathroom, Then I can move the balance all the way to the left for outside and right for the bathroom. By pressing the mono switch I 'm not missing out on any of the music. This would only be for occassional use with these speakers, the main speakers are q acoustics 2050 in high gloss white with a Sonos ZP90. All in white so looks and sounds sweet. If the AMP was white sthis would be a bonus Thanks
