Yes, Antonis. I do understand how to measure the back
response anechoically but the whole idea of doing it in place, factoring in the
effectiveness of the corners. I do not know how to do it.
Regarding the Rebel++ impedance, yes it was my initial reaction
but there is so much more to it that keeps my mind occupied for a while and I
do not have the answer as of now. You see, the fact the tube Milq was objectively
falling is a good indication impedance drop beyond where Milq can handle.
Still, 2 other amplifiers were B2 and B3 that have no problem with low impedance.
The failure with B2/3 aps was not so catastrophic but the “great” sound was not
there.
My focus now is ironically not on Rebel++ , the speaker is
good but no better than it might be. At this point I feel that the exceptionalism
is not coming from the Rebel++ but from this shitty Denon table radio that I
drive Rebel++. I have had this unit for 17 years and it was very good for my office,
bedroom etc. I have not had a good full range speakers for over 20 years and
the story with Rebel++ was a first time I was driving my little table radio against
a “serious” speaker. I am more than impressed. Some of the things I am getting
is would be VERY rare for any amplifier of any class and I am getting it from $100
CD/DAC/AMP combo!!!
The last night I was listening to Ivan Fisher’s Maler 2 with
Budapest festival. I am not kidding, the Rebel++ overperformed my main system. Was
sound better with Rebel++ then Macondo? No,
it was even remotely close. Still, I feel that Rebel++ was advantageous in my view. You see, Fisher’s
Maler 2 is good performance but not consistent. There are some moments that are
spectacular with very sensible personal touch but there are some moments when the
orchestra just run through the score and make music boring and not expressive enough.
Macondo, being the system that does very good audio, slightly masks out the
boring moment of the performance by showing off a remarkable audio expressiveness.
The Rebel++ and this shitty Denon do not do it at all and
the boring parts are truly deep-boring. This is VERY advanced characteristics
of a playback, and it is VERY hard to get. The fact that this shitty Denon and Rebel++ somehow do it is a huge mystery for me. Rerurn to Romy the Cat's Site
