I tested some active monitors against solidstate guitar amps in the shop today.
I used Bert meulendijks profiles (most agree this is top quality), and my prs 513.
My observation is quite different then what i find on this forum...disclaimer...hey...its just an opinion
I tried the Yamaha dxr10. This to me sounded not good at all. Highs were nasty at high volumes, killed a lot of dynamics i hear on my studio monitors, also sounded "boxy" and artificial...compared to an "amp in the room". I used to play miced cabinet over a monitor, it beats that...but to me no where near to an "amp" sensation.
I also tried aer monitors, idnk the model, those to me where a lot better...but still not what i look for.
Then cab sim off and plug-in returnes of solidstate combo's.
I tried a Roland jc120...that sounded a lot better, right from the first note...very usable and open.
The sound was maybe a little more compressed then desired, i used to play a jc...that struck me as charactristic for the amp.
The smaller version of the jc was to agressive in highs at higher volume.
The second Roland...a bluesxxxx (cant remember), sounded more open, less compressed, required a little damping of high and présence.
The third...and remarkably my winner: a cheap ass 300,- Boss kantana.
I had the whole sales crew there scratching their heads how on earth that sound came from a Kantana.
My next step is to compare between tube combo and solid state combo...but for now...any solid state combo with a Kemper gives me better results then i have had in a lifetime of experimenting!
