I've 1/3 of this combo ... and I know what you mean. I keep harping on and seems to be lost on many ios how long the Burmester electronics have been so good: so long they are forgotten when people are listing the best electronics around... The 911 is a 25 years old amp ... I repeat
25 years old .. the 805 is simply astounding in this world of an update per year in High End Audio... 36 years old!!! Having debuted in 1980 !!!!!
With the right speakers, meaning very efficient and with well-behaved impedance curve, the 956 gives little to the 911 IME
Burmester was once considered very expensive , now they are kind of middle of the road in term of High End Audio prices and because of that they aren't often not mentioned in the Best at any Price category... Those who own them or have heard them in the proper settings, acquire them and are done .. end of the road for them .. perhaps something many audiophiles secretly don't wish
