It's not (just) the caps, it's the placement, layout and the routing.

Another shorcut question, from what slew rate usually are opamps considered "fast opamps". Aprox.., or just looking at the seller label?

IMO slew rate stopped being an issue for audio opamps since the 553x and TL07x families came out in the '70s(?). For good performance when working around digital circuitry that can generate much higher than audio frequency noise, I suspect gain bandwidth is more important than power bandwidth (slew rate) for maintaining low source impedance. Also power supply rejection vs frequency now becomes an issue with higher than audio frequency PS noise possible.
