Amp. without Remote control

I am using MF X-A1 , which has no remote control and very inconvenient, what can I add to the system to make me remote ly control the volume. Thanks.
Add on remote separately will effect the sound of your system, at lease for me! ?!...good luck, rute.
I saw a box like this in the audio shop: i think it was a Creek add-on box with remote controlled attenuator. Probably would affect your sound performance though, especially since the signal must route thru 2 more pair of interconnects. Put it thru a tape loop, so then you can switch it out for critical listening.
