What do LR, CS, and SR stand for?

This may not be the right thread for this question, but video switching aside, why would one opt for the 621 box versus the modded oppo approach?

You would set the Oppo to convert DSD to PCM, which is then output from the 4xSPDIF mod.

Trouble with the mod board is that my 861 always thinks its getting 6 channels so I setup a phantom input for 2-channel SACD that I can use Trifield, etc.

LR = left/right; CS = center/sub; SR = surround; BS = back surround (those were the designations on the 4xSPDIF board).

My own 2 cents: Advantages of the HD621 include the apodizing filter and the ability to utilize more than one source. Advantages of the modded Oppo are lower cost and doesn't leave me short a digital MCH input. If the HD621 had a 3xSPDIF pass-through or Meridian has given me some idea of when a MMHR input for 861 might be avaiable i probably would have gone that route. As it is, i can still do that in the future if it makes sense, but enjoy higher-rez Bluray audio right now.
