Different price classes - Schiit Tyr F costs roughly 1.7x what Marantz MM7025 does. Expect it to lead on paper; the question is whether you will hear the difference through the speakers you own.
| Area | Better | Why |
|---|
| Power | B | Schiit Tyr F has more power - 200W against 140W into 8 ohms. That is about 1.5dB, which is a small step in loudness but real headroom on peaks. |
| Bass control | B | Schiit Tyr F has the higher damping factor (200 vs 100), which usually means a tighter grip on a woofer. Above about 100 the returns flatten out, so read this as a tendency rather than a ranking. |
| Noise floor | B | Schiit Tyr F is the quieter design on paper - 120dB against 105dB. Audible mainly with sensitive speakers in a quiet room. |
| Analogue inputs | evenly matched | The same number of line-level inputs (2). |
| Price | A | Marantz MM7025 costs less - $1,000 against $1,699 at list. |

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?
The usual trade-off: Schiit Tyr F measures better, Marantz MM7025 costs about 41% less. With most speakers in most rooms that gap is smaller in practice than it looks here. Think about the whole system: the roughly $699 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.
