If you need a flexible amp with tons of authentic amp profiles and effects, endless routing options and and and: Kemper is the thing!
If you need only one tube saturated sound you can play at bedroom volumes there might be a few different options on the market.
For example: low wattage amp -> power attenuator (with load box option) -> speaker emulation DI box -> interface -> monitors
If authentic tube saturation sounds don´t matter to you too much other digital amps on the market could make you happy as well.
I was struggling for a long time with getting saturated valve sounds at lower volumes. The only thing that helped me was either lower wattage amps or
power attenuators or both at the same time. Since I own a Kemper I don´t have that problem anymore.
Good Luck!
