I still own a 335 and it has the removable power cord that was replaced even before I plugged it into the wall the first time with a BMI Whale elite. Huge difference in soundstaging and low end reproduction. The even bigger difference sonically in my system was the addition of adding a 20 amp dedicated line for the amps. It opened up the dynamics and reduced the noise in the system even more. I would suggest trying that first?
Power Cable options for Levinson 300 series
I currently have the Levinson 33H's, and before them the 336. Both these amps have a Levinson power cable built right into the Chassis. Knowing how much a good power cable can improve a component, I am wondering what I could be missing in improved performance if I was able to put an after market cable on my 33H's. Does anyone know of any way to make this happen for the 300 series, as I believe they all, from the 331 to the 336, and including the 33H and 33's..........have built in power cables!
