Give the amps more time to break in, what you are describing in the midrange is typical of later stage break in of active electronics. The mids are the last to open up and come on tune and can sound recessed. Also, in a live room, what you said of the tweeter's dominance is true. So do consider soldering in a resistor. get a few values of wire wounds 0.3 to 1 ohm to try out.

What wires are you using?

Re Pre - it is common practice to use a tube preamp with high power SS amps to allow rolling tubes to fill out the midrange and "sweeten" the top end.

The biggest compliment you have given the amp is that it is showing off differences between recordings that were not obvious to you before.

Once a non fan of Jazz curious about my setup came to visit and said that all recordings of each Jazz group were pretty much the same to him since he didn't care for the music itself that much. So I went and played him some Jazz and he was astounded as the recordings sounded wildly different from one session to another and even live recordings (Judy Carnegie Hall, MJQ last concert) were entirely different from one group of tracks to another. He said that he is getting a clue as to what Jazz is all about. Observing him listening I though he was wrapped in the music and oblivious to what I was doing - so I carefully warned him each time before I changed sources or recordings so that he would not be jolted out of his bliss. He seemed disappointed each time I suggested a switch to something else, like he just started getting into it.

Thanks for a very detailed review with useful descriptions.
