Interfaces & preamps for competitive FPS
An XLR mic needs an interface for clean gain and (for condensers) 48V phantom; a low-output dynamic like the SM7B often wants an inline preamp on top. These are the interfaces and inline boosters AimBench tracks, by price.
Why these make the list
What earns a place here: enough clean gain and (for condensers) 48V phantom to run an XLR mic quietly. Interfaces convert + power the mic; inline preamps add gain ahead of a hungry dynamic like the SM7B. Both are tools matched to a mic, not a sound upgrade.
How to read the ranking
Pure sufficiency — once it powers your mic chain cleanly and quietly, more is just extra inputs, outputs and routing, not cleaner gain. Match it to your mic: a condenser needs phantom; a low-output dynamic needs high gain (or a preamp). Pick the tier that covers that, then stop.

Price classes are coarse, drift-proof bands (the live local price is on the buy link). "Enough is enough": for amps and mic chains, the goal is sufficiency — once a tier clears your needs, a pricier one rarely sounds better. Buy links are affiliate links to your regional store.
