Much more than just changing the name and adding a volume knob has been done. It took over a year to design and test the new m11. It's similar to the reference 10.32 but fixed all of its shortcomings that made it so unpopular. The new amp on the m11 is pretty epic. I think it was a much needed upgrade. For me, it was the volume knob to be honest. I find buttons to be simply unacceptable. I think the m11 will be a success. I don't consider the sound signature to be U shaped unless it was more extreme. Maybe u shaped yet mostly balanced and neutral. The mids are pretty sweet and just slightly recessed to my ears. The upper details remain and treble is reduced compared to sabre dacs of course. This is definitely a good thing. No longer is it fatiguing at all! The tune of the m11 is close to perfect for all music types. I'm very pleased with its sound signature. I don't think any one dac/amp can please everyone... But the m11 might come close. I am getting the amanero combo 384 today in the mail. I hope to compare with the via32 and will post my update in the next week. I'm glad I don't have a Mac, seems some guy is having problems with his Mac and the amanero. Hope the bugs get worked out!
