Over the years, I’ve come to learn and appreciate the difference between articulate bass, bass bloom, and ‘bass slam’. Bass bloom, which is what you get with many low to mid priced tube amps can sound pleasant at first, but it also tends to hide the details, especially in and below the midbass region. It lacks that visceral impact that you sometimes crave. As mulveling mentioned, you need to go up to the big boy tube amps to get that, but they tend to be expensive to buy and maintain.
Bass slam, while impressive at first, can get fatiguing after a while. IMO, it also takes away the musicality. I found that some SS amps have too much damping going on resulting in bass slam.
what I did to learn the difference was to visit a lot of jazz clubs to understand what real drums sound like. They’re definitely not what it sounds like in most systems. I’m gradually tuning my system to approach the real thing but I’ll admit I’m far from the real thing and might not get there. But I’m getting closer.
