Hi, Both these processors are available for 300$ at zzounds.com.Now i am about to order one from the US. So what are your experiences with these? As far as i heard the gnx works only with 110v which means i need a stabilizer for it which could trouble me every now and then due to voltage fluctuations.Is that true? Which one has better sound quality?Actually i had a chance to play on GT-6 and found it amazing,but then i would even found a zoom505 amazing as i am new to them. Waiting for your replies.
