Ok... so I wasn't patient. I took a break during the day to go home and hook up the M11.... only have about 20min or so to play with it.
So far it exceeds my expectations by quite a bit!
I've been listening to the NFB28 the last week since selling my DAC19.
But i'm familiar with the DAC19 as well.
It's notably better than the DAC19 even! I didn't expect that at all.
Not saying the DAC19 was a slouch... but I will do some critical listening later on tonight and this week.
So far.... it's a sure winner.
I play several tracks i'm very familiar with and I immediately noticed the sound stage is much wider than before. Maybe i'ts my imagination...but maybe it's because it's balanced and the separation is much better.
I was using RCA's to connect the DAC19 to the NFB28
now its pure class A on the M11 and boy does it sound amazing.
