These are not the same size of amplifier: Schiit Wotan has roughly 2.2x the power of JBL SA550 C. That is about 3.5dB, so it is a question of room size and how hard your speakers are to drive, not of one being the better amplifier.
| Area | Better | Why |
|---|
| Power | A | Schiit Wotan has more power - 200W against 90W into 8 ohms. That is about 3.5dB, so it plays usefully louder before it runs out and has more in hand on peaks. |
| Room size | depends | We rate Schiit Wotan the better fit for a large room and a very large room, and JBL SA550 C for desk or near-field listening, a small room and a mid-size room. Match the amplifier to the room you actually have, not the one you want. |
| Grip on hard loads | A | Schiit Wotan holds up better into a 4-ohm load: its output nearly doubles to 400W, where the other increases strongly. That matters with demanding speakers far more than the 8-ohm figure does. |
| Noise floor | A | Schiit Wotan is the quieter design on paper - 124dB against 106dB. Audible mainly with sensitive speakers in a quiet room. |
| Built-in DAC | B | JBL SA550 C has a DAC on board; the other needs an external one, which is another box, another power lead and another purchase. |
| Analogue inputs | B | JBL SA550 C takes more analogue sources - 3 against 2. |
| Phono stage | depends | JBL SA550 C has a built-in phono stage (MM) and Schiit Wotan does not. Decisive if you own a turntable, completely irrelevant if you do not - and an outboard phono stage is easy to add later either way. |
| Headphones | depends | Only JBL SA550 C has a headphone output. Worth something if you listen late, nothing if you never do. |
| Amplifier class | depends | Schiit Wotan is Class A/B and JBL SA550 C 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 | Schiit Wotan takes up about 14% less shelf area (1342cm² against 1565cm²). |
| Price | evenly matched | Priced within a few per cent of each other. |
| Watts per dollar | A | Schiit Wotan is the cheaper watt - about $10 per watt against $22. A blunt measure, and it says nothing about how either sounds, but it is the honest one for raw output. |

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?
Schiit Wotan has the edge on paper, though not by much. The rows marked "depends" are more likely to decide this than the score is. If your speakers are a difficult load - 4 ohms nominal, big woofers, or a sensitivity in the low 80s - Schiit Wotan is the safer partner, because how an amplifier behaves when the impedance drops matters more than its 8-ohm rating. Start with the room. In a large or open-plan room, or with speakers that are hard to drive - low sensitivity, or an impedance that dips - Schiit Wotan has the headroom, and headroom is what stops an amplifier hardening up on peaks. At desk distance or in a small room, 90 watts is already more than most people ever use, and the extra 110 watts would be headroom you pay for and never hear - we rate Schiit Wotan poorly for near-field use for exactly that reason.
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.
