Hi guys, I need to record piano recitals with 3 or 4 Audio Techinca mics. I use MOTU 896HD with Macbook Pro and Logic Pro, but it isn't really a "portable" solution. So I wonder if TASCAM DR680 or ROLAND R44 could be a good solution. In your opinion MOTU's preamps (and generally the recording quality) are better then DR680 and R44, or not? Quality is similar or not? Thanks for your answers.
