I already have FX-850. Looking to upgrade. I asked about FX-1100 if its significant upgrade from FX850 for a fun type sound signature but if it is not then i would not mind giving DN-2K/J a try for a different sound signature to see if i like it. Would you recommend the new DN-2KJ over the old DN-2K ? Trying before buying is not possible here in India because they must be imported here. They are not available locally. Hope i am clear enough now.
