Do I care if Laddered stepped attenuator is 100k ohms?

I am looking at a 100k laddered stepped attenuator for a project. The attenuator would go between a DDDAC 1543 DAC and a BOSOZ pre amp.
Normally I would use a 10k attenuator, but a 100k is available. Do I care if this attenuator is 100k ohms?

The Mosfets of the BOSOZ have a bit much input capacitance for a 100K pot.
You could consider that circuit done with N channel JFETs and I'm sure it would
work fine.

Nelson...thanx for your reply...Can I just plug in JFETs in place of the Mosfets??? or should I do a search on DIYAUDIO to see what needs to be done...

I think there's a thread somewhere...
