A couple thought to consider, since you have a few weeks before you need to make a decision.
If the amps are brand new, they're maybe still breaking in. The sound will be a little more vivid after they are fully broken in. Make sure they ARE broken in ASAP so you're really hearing them properly.
Also, your speaker/listening positions, dacron stuffing, etc. are still probably what you found worked best with your prior amp. You might be able to get what you want for free just by going through that process again.
In the same vein, try a few other cables if you can during the next couple weeks, since it sounds like you're already pretty close to what you want, and you might feel compelled to do this anyway once you've got the amplifier thing settled.
