@rizwanalimohd There was a British review of the 509x integrated and it stated that the preamp and amp sections of the 509x were derived from the 700 series. If I can find that review I will post on this thread (later tonight if I find it)
I have demoed both the 509x and the 900 series on the same system and the differences were rather large in favor of the 900 series.
@mountainsong What preamp or DAC with volume are you using the m900u amps with? I am thinking of going with the $2.5K Benchmark LA4 preamp instead of the $15K Luxman c900u preamp. I will do a 30 trial with the LA4 preamp first but I was curious if others used anything other than the c900u.
