One is a streaming all-in-one and the other is an amplifier. Judge them on how many boxes you want and what you already own, not on the spec sheet alone.
| Area | Better | Why |
|---|
| Power | B | JBL SA750 75th Anniversary Edition has more power - 130W against 90W into 8 ohms. That is about 1.6dB, which is a small step in loudness but real headroom on peaks. |
| Room size | depends | We rate Yamaha A-S2200 the better fit for a small room, and JBL SA750 75th Anniversary Edition for a large room and a very large room. Match the amplifier to the room you actually have, not the one you want. |
| Grip on hard loads | evenly matched | Both behave much the same into 4 ohms - output increases strongly (150W and 200W). |
| Noise floor | evenly matched | Much the same signal-to-noise ratio (110dB vs 112dB). |
| Built-in DAC | B | JBL SA750 75th Anniversary Edition has a DAC on board; the other needs an external one, which is another box, another power lead and another purchase. |
| Streaming | B | Only JBL SA750 75th Anniversary Edition has AirPlay 2, Chromecast and Roon. |
| Analogue inputs | A | Yamaha A-S2200 takes more analogue sources - 5 against 4. |
| Room to grow | evenly matched | The same expansion options on both. |
| Amplifier class | depends | Yamaha A-S2200 is Class A/B and JBL SA750 75th Anniversary Edition is Class G. Class A/B runs warm and is the long-established mainstream choice; Class G/H switches its supply rails to cut the heat a Class A/B design wastes. Modern examples of both measure well - judge by the rest of the page. |
| Shelf space | depends | JBL SA750 75th Anniversary Edition takes up about 19% less shelf area (1718cm² against 2127cm²), and it is 108mm shallower, which is the measurement that decides whether a rack door shuts. |
| Price | B | JBL SA750 75th Anniversary Edition costs less - $3,000 against $4,500 at list. |
| Watts per dollar | B | JBL SA750 75th Anniversary Edition is the cheaper watt - about $23 per watt against $50. A blunt measure, and it says nothing about how either sounds, but it is the honest one for raw output. |
A Yamaha A-S2200 B JBL SA750 75th Anniversary Edition
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both amplifiers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
JBL SA750 75th Anniversary Edition is the easier recommendation: it leads on most of the measured areas and costs less. Take Yamaha A-S2200 if one of the "depends" rows above describes your system. If you already own a DAC or a streamer, the built-in one is money you are paying twice for, and Yamaha A-S2200 becomes the more rational buy. Think about the whole system: the roughly $1,500 saved by taking the cheaper one would buy better speakers or a subwoofer, which does more for the sound than the difference between two competent amplifiers.
What a spec sheet cannot show: how either sounds with your speakers, how the controls feel day to day, and what the app is like to live with - which is where most all-in-one amplifiers are actually won or lost. Power figures are the manufacturers' own and are not measured to a common standard, so treat small differences as noise. If you can hear both, that will tell you more than any row above.
