It is great you have love the sound of your gear. That was incredibly likely if you moved from lower level stuff and this is your first jump into the high end... any flavor of high end is likely to be a revelation. As it should be. We don't spend tens of thousands of dollars on audio equipment to get rid of our money.
Companies have house sounds. This is very true with Burmeister. They have a particular sound... very discrete, very detailed, powerful which translates in holographic sonic spectacular through good speakers. As opposed to being musical and having a natural presentation.
It isn't much about circuitry as it is about power. You will get a lot more oomph with a set of Burmeister monoblocks and even better imaging. An audio designer could use exactly the same circuitry in two amps or preamps and by the choice of its components make them sound completely differently.
If this has gotten you interested in in the high end... I recommend reading Robert Harley's book The Complete Guide to High End Audio. It is a whole world unto itself, and this is a great introduction.
If you go ahead and get the monoblocks, you are likely to be very pleased... but you will not know if going in a different direction would have been much more rewarding.
