hey, glad you posted this for all to see. I've only had my 990 for less than two weeks at this posting.

Yeah something i'd have done different on the 990. I'm not sure I completely understand that "bass issue" people are talking about. Although I do have to say...that i'm having trouble finding the right balance in my bass with the 990 pre.

It's either to low for home theater and to loud for 2 channel listening. Not sure if this is the problem or not.

Also, i use a set up disc i use in my DVD player.. and manually set up all the speakers. I start with Dolby Digital, then once those levels are set with a SPL meter.. i usually move on to DTS and run the set up manually again. What i noticed is that there is no difference in the DD and DTS settings. The pre doesn't remember different settings for both formats.

I'm used to setting up for DD then for DTS.. and my Marantz would remember the different setting for each format. We all know that both DD and DTS sound different.. so the 990 pre should remember the settings for each different format. Meaning one size doesn't fit all.
