Compare the ABYSS Diana TC Signature and Diana MRx headphones: resolution vs bass extension, build materials, and which audiophile should choose each model.
Quick answer
The Diana TC Signature prioritizes maximum resolution and refinement for critical listening, while the Diana MRx delivers extended bass response below 10 Hz with a lighter, more comfortable frame. Choose the TC Signature if you value micro-detail retrieval above all else; choose the MRx if you want powerful, flat bass without sacrificing comfort.
Build and comfort differences
The Diana MRx uses newly redesigned CNC-machined aluminum frames that are lighter in weight than the previous generation, improving long-session comfort. The Diana TC Signature also employs precision CNC machining but focuses on a frame optimized for head acoustics rather than weight reduction. If you plan to wear the headphone for hours during critical listening, the MRx’s lighter build may be more forgiving, while the TC Signature’s chassis is tuned for acoustic isolation and rigidity.
Bass performance and tuning philosophy
The Diana MRx features ABYSS’s EBR (Extended Bass Response) technology, originally developed for the flagship Diana TC Signature, and achieves a flat bass response below 10 Hz. That means you get sub-bass extension that is physically felt rather than just heard, ideal for electronic, orchestral, or bass-heavy acoustic tracks. The Diana TC Signature, by contrast, is voiced for the most experienced listener who values resolution and refinement over bass quantity. Its bass is accurate and controlled, but it does not emphasize low-end extension the way the MRx does. The trade-off is clear: if you want visceral bass impact, the MRx is the better choice; if you want every micro-detail in the midrange and treble, the TC Signature excels.
Trade-offs between the Diana TC Signature and Diana MRx
- Resolution vs bass extension: The TC Signature offers higher resolution and refinement for critical listening; the MRx provides deeper, flatter bass below 10 Hz. You cannot maximize both in one model. Choose TC Signature for detail, MRx for bass impact.
- Weight and comfort: The MRx is lighter due to its redesigned aluminum frames, making it more comfortable for long sessions. The TC Signature’s heavier chassis is optimized for acoustic performance, not weight reduction. MRx wins for extended wear; TC Signature prioritizes acoustic rigidity.
- Price and value: The Diana TC Signature is priced higher (catalog comparison $4995, current $3196.80) than the MRx (catalog comparison $3295, current $2042.90). The premium reflects the TC Signature’s extreme refinement and flagship status. MRx offers strong bass performance at a lower price point.
