Lamm LP2 Deluxe vs. Manley Steelhead

I can't do a comparison, but I've used the Lamm for more than a year and love it. I use it with a Koetsu Rosewood Signature, which is a pretty low output cartridge, and it has been fine. One point, which might be of interest: even with sources that have more than enough output, I find that increasing the input gain on the line preamp can sometimes have a startling effect on dynamics. If you increase the input gain on my Synergy IIi and decrease the master output volume, it sometimes makes a noticeable improvement on certain inputs, and the LP2 was one of them. Of course, it helps a lot if you have individual gain settings for each input. Also, it could be that it is the line preamp which is working better with the gain increase, but that's another question.
