Funny thing people dont realize is that the ML 4 series amplifiers is NOT an upgrade from the 3 series amplifiers. In fact the 4 series Mark Levinson amplifiers use alot of parts from the older less expensive Proceed line that was discontinued. I have heard both extensively. Both sound very similiar, but then again I could also state that Proceed HPA amps and 3 series ML amps sounded about the same too, but there in lies the full circle. Lets pay twice as much money now for an HPA series Proceed amp with the ML tag slapped onto it. That is in essence what the new 4 series amp is all about. I used to sell Proceed and ML and know the company very well.
Stick with your 3 series amp. Send it back out for repair, or better yet, get it repaired and upgrade to a ML N0. 335 or 336 which is basically a small improvement in design and reliability over the first 300 series amplifiers made from ML such as the unit you have.
