Adcom GFA 5500 v B&K ST 1400 II v Rotel 990


Hui, I picked up a Adcom GFA 5500 MOSFET amp . I am using a GTP 565 preamp with it. At this moment Vandersteen 2CEs with AP Oval 9s and Solo crystal ovals. Marantz SACD 7001 is the main source.

Would there be any reason to switch to a B%K ST 1400 series II? I have had the B&k ST 140 vesions and thought they were musical but a little dark and the speakers are different so hard to be sure. My take on the Rotel 990 ve the Adcom is the Rotel is alittle grainy or sandy sounding and the stage is not as large and sounds more congested then the Adcom. Not sure a Rotel 990 or 995 preamop would help as I have had them and feel that they are somewhat veiled and dark (much to my surprise) This has been pointed out in some reviews. Maybe it is just between the Adcom and B&K?? FYI I think the 5500 has a larger stage then the 555II I borrowed and is not quite as mechanical and dry.
Thoughts before I do something stupid.

Going to a GFP-715 is a lateral move. Here is a user review that compares 565 to 715...

You haven't said what your budget is and what you are looking to gain with an upgrade.
