Ronnie:

Very well reasoned. I am in a similar place as you, although non-Meridian passive speakers rather than older DSPs' - but still no use for speakerlink.

I guess it is not clear to me whether apodizing is possible in the current configuration/processing power of v4, or whether a v6 is required. If the former, then the cost of v6 becomes somewhat less appealing.

I am also unclear on the benefits accruing from moving to the newer analog output cards (OA3/OA13 to OA8/OA18) nor whether those new cards will be 'required' in a v6 implementation.

Answers will be forthcoming, of course, but for now, 'clear as mud'.
