Hello

My system is G61 (not the model), G08, Sony BDP-S550, 558.2, B&W 802D- mains, B&W HTM2D -center, Velodyne FSR12- sub, B&W LM1- surrounds (wife acceptance factor.)

I have the Sony BDP-S550 connected to the G61 via multichannel analog.

Would the same list of advantages vs. disadvantages apply?

Would integrating the HD621 to my system improve the 5.1 sound quality enough to justify the cost?

Also I may have misunderstood a previous post but did I read that Meridian might provide a 4X SPDIF upgrade for 7.1 Dolby TrueHD , DTS -HD Master Audio. If so, could this be done via firmware upgrade and would Meridian apply this upgrade to the G61?

Thanks,
Jim
