Luxman C-02 remote? And sound signature

I probably read too many forum discussions.  Anyway, I have a Luxman R-117 integrated amp.  I have been pleased ad punch with, but I have read many articles regarding that it’s pre-amplifier isn’t as good as it could be or should be; so I acquired a Luxman C-02 control amp/pre-amplifier. Two things I’ve noticed: 1) I seem to have lost that warmth and depth that the R-117 provided.  In its place is a very punchy, but for lack of a better word crisp or airy top end without the depth from before, is this normal?  I have to say it’s really clean, but maybe too crisp. Maybe my ears need to adapt?  Both sound good but different. I think I miss the warmth and the bottom end.  2) The upside the remote control associated with our 117 is now disabled and the C –02 never offered a remote, so I guess I’ll be getting a lot more exercise because I did not realize how often I have to get up for my comfortable listening position to adjust the volume, specifically when I’m listening to a streaming device.  It’s amazing how every song, every artist, every album, every label…seems to have a different baseline for it’s initial volume.  I am not aware of any aftermarket or OEM device that serves as a adapter or infrared receiver to enable a remote control to work with the C – 02.  Any input is welcomed and appreciated.
