Hi
@cenizas, I did further A/B testing this week for the SMABAT M2 Pro vs the original SMABAT ST10.
This is using full foams with tuning module 0 (ie V shaped and bassier tuning module) on the SMABAT M2 Pro:
- The ST10 has better bass extension and quantity even with the SMABAT M2 Pro on the most bassy config as above.
- The ST10's note weight is slightly thinner with a slightly cooler tonality and less authentic timbre than the SMABAT M2 Pro. M2 Pro sounds more analoguish and nebulous.
- SMABAT M2 Pro has slightly more recessed lower mids.
- Technicalities wise, the ST10 is ahead, with better soundstage, better imaging, instrument separation, clarity and details on the ST10. In fact imaging and instrument separation are one step behind on the SMABAT M2 Pro compared to the ST10, especially when it comes to complex tracks.
- Fit wise, the ST10 is larger and slightly less comfortable.
Since you own the Black Gold version, which is the supposed successor and upgrade over the original SMABAT ST10, and with the M2 Pro already losing to the ST10 in technicalities, I would suppose the M2 Pro would also be a downgrade for you in the area of technicalities. Never heard the Black Gold or Black Silver ST10S sets, so I'm not sure how their timbre is, but probably SMABAT ST10S Black Gold and Black Silver are still deserving of the flagship status even with the new kid on the block in the M2 Pro.
