I have duplicated the filters installed in the main receiver for my sub receiver. There are five filters in each. I really think it comes down to what you intend to use the sub receiver for. If you use it to check out another part of the band or another band altogether while working a Qso or simply listening to one portion of the band while wanting to check another band for activity, then I think the wider filters will suffice. I also think the narrower filters are more important for CW operation than they are for sideband, although, I realize opinions on that will vary.
If you want to use the sub receiver during split operation then perhaps the filter selection becomes more critical. Perhaps you should consider one wide and one narrow filter to start with and then see how you use the sub receiver and whether or not that filter lineup is adequate. If you do not plan to do diversity reception I think you will find that the use of the sub receiver is relatively limited. But again, it depends on your operating habits and interests. As far as the DVR is concerned, I do have it installed in one of my k3s and I do have another DVR but I have never installed in the second k3. I am not a contester. I think it would be of most use for calling CQ or giving canned reports during a contest. Because I do not engage in that activity, it is of lesser importance to me. I do use the CW memories however. But they come with the radio. I can't answer the question of DVR versus another filter because that depends very much on your operating interests and habits. Perhaps it would be best for you to hold off considering that and just experiment with the operation of the new sub receiver. If it is configured in a way which satisfies your use and does the job to your satisfaction, then perhaps it is time to consider a DVR. But if you are bothered by any IMD in the second receiver and that is important to your operation, perhaps acquiring a suitable additional filter would be a better choice. I think you will need some operating experience with the new set up before you can decide that.

Between my birthday and Christmas my wife has OK'd the purchase of the sub-receiver for my K3 (#6623). I have read the recommendations by Wayne on the order site and originally thought I would just duplicate the filters in the main receiver (2.7, 400, 200) as I do mostly CW and Data but I do enjoy casual SSB also. I note form Frank Cady's book that the primary reason for having the filters the same is diversity reception and that do not need to be the same. Right now finances only allow 2 additional filters. So I have been giving it some thought - would it be reasonable to put say a 1,0 filter and a 2.1 filter in the sub or perhaps match the 400 and add either a 1.0 or 2.1? I realize that my operating style influences this - I am not a contester - just enjoy casual operating and some DX. The other issue would be adding the DVR - I was thinking of getting it just because it looks like it is easiest to install it at the time of the subreceiver addition though I am not sure how much I would use it and if I don't get it - I can probably add one more filter. "Found" Elecraft last Spring - now have K3 and KX3 and love them and this reflector.
