I’m not a fan of trying to shape the tonality of an amp/speaker combo using DSP/EQ. If there’s a specific room anomaly you’re trying to correct then maybe, but if an amp is lean sounding by nature, then trying to change its characteristics digitally doesn’t make a whole lot of sense to me. (Disclaimer- I’m old).
I’ll throw in another vote for Synthesis amps. I bought a Titan A100 before the holidays and it’s a fantastic amp. Big, bold, dynamic, full bodied, extremely easy to listen to. I can’t see myself thinking about another amp change for days… weeks even;)
