@shuffleboard:
You need a player that internally decodes everything (DD+, DTS HD, TrueHD, etc.) and have the following options:
1) Buy a player with 5.1 analogue outputs to connect directly to the G68.
Advantages: Cheap; simple.
Disadvantage: Extra D2A and A2D conversions; music bass management layout applied.
2) Buy a player in the States, ship it directly to Shawn Fogg for a 3x (or 4x) SPDIF modification (or buy a 3x SPDIF card from Shawn and manage the modification yourself). You can then connect it digitally to one of the two G68 multichannel digital inputs.
Advantages: Cheaper than HD621 solution.
Disadvantages: Logistical nightmare if you want a Region B player; music layout applied; higher jitter?
3) Buy a player. Buy a modified CLUX11SA (or Octava) from Shawn Fogg. Connect player to CLUX and CLUX 3x SPDIF output to the G68.
Advantages: Cheaper than HD621 solution (and works with G68 FIFO buffers), CLUX will work with more than your Blu-Ray player.
Disadvantages: Undoubtedly a higher jitter solution (though will you hear the difference with FIFO in the G68 and DSP speakers?); music layout applied.
4) Buy a player and the HD621.
Advantages: Lowest jitter solution, proper Meridian support and integration.
Disadvantage: Cost.
Or 5) Wait till Meridian releases a proper onboard solution.
My guess is they produced this box to keep their customer base happy and not to scare off potential customers. But really they rather would have waited untill the HDMI specs are up to their standards. Which I really do not understand, because ie. is the SPDIF spec that great? This is where the high-end companies can make their difference !!!
