Medea+OP1-BP & Medea Original Analogue Boards.
Although the latest Weiss Medea+ looks very similar (some may say it is even the same) as the original Medea, the biggest different lies on the DAC & Analogue board.
Medea+ & Original Medea DAC/Analogue Boards Differences

Millions dollar question: Why their outlooks are so similar but big differences inside?
Answer: Medea(Medea+) is Weiss flagship DAC, We want it to have a very long life span.
Question: Almost 12 years are not long enough, are you serious ?
Answer: We are very serious, and all features are upgradable.
1) DSP & Digital Input Board
- First Generation: Dual AES only for 176.4/192kHz
- Second Generation: Single & Dual AES are supported for 176.4/192kHz
- Myth: Dual AES sounds better than signal hi-speed AES because it uses 2 AES cables
- Truth: Dual AES appeared before AES/EBU specification accepts single hi-speed at 192kHz. It has nothing to do with two is better than one. Single AES is better because it is simple, save 2nd AES cable and input phase matching.
2) DAC / Analogue Board
- Original Medea. Designed in 1999, still a classic.
- Medea+OP1-BP: Designed in 2011, State Of The Art.
- Fully upgradable by replacing the entire DAC/Analogue board with the latest Medea+OP1-BP Board
- Local distributor/reseller is capable to perform this upgrade.
3) Firewire IEEE 1394 input & ST Optical input
- Fully upgradable for compute source playback and ST Optical input for Jason ST Optical connection
- This requires send back to Switzerland Weiss headquarter for upgrade
- Upgrade includes Firewire IEE1394 volume/phase remote control & RF receiver set
- Upgrade includes single way shipping fee from Switzerland headquarter back to user address after the upgrade.
