pre-amp processor


i'm trying to decide between the  Lyngdorf MP-60 2.1 

and the Acurus ACT 4 any thoughts and information woul be of great help

I think the Lyngdorf is going to have much more flexibility in configuration.  The configuration settings in the Acurus ACT 4 are somewhat limited.  That being said, it is probably all about sound quality and I don't know that anyone here would have compared these two items side-by-side or at different times to give you an idea on the differences.

So, did some searching around.  I have never been able to find an internal pic of either of these processors, but it seems like there are a couple pages showing internal of the previous MP-50:

Both pictures show that the Lyngdorf is run off a switching power supply.  This would be one reason I would avoid the Lyngdorf (even though many people rave about this processor).

Both the MP-50 and the new MP-60 are exactly 19lbs in weight, so I can only assume the MP-60 is also based on a switching power supply.

The Acurus ACT 4 is 25 lbs in weight.  Ah, here's a thread that has an internal pic:

It seems the ACT 4 is also based on a switching power supply.  It's up to you, but at this point, I would not consider either processor.  I would probably go for the McIntosh MX-160 (which is a Lyngdorf digital processing platform with McIntosh linear power supplies and analog stages).
