1. in terms of sound quality, qobuz hi-res > tidal masters but both are very very good, and the difference is relatively small
2. your rotel and totems produce a clean crisp extended somewhat lean sound with good bass -- do you want a warmer richer fuller sound? if so, there are dacs worth trying, but you should disclose your budget
3. the d-to-a conversion chips used in dacs matter, but only about 25-40% of the overall sq produced... other factors matters a lot, especially power supply, jitter management, output stage and tuning of the sound profile by the maker
