How is LAMM LP2 compares to the more recent phono

This is the confusing part for me. I looked at old Stereophile review and it did say that loading is 40 ohms. However, if I am not mistaken, the step up transformer inside LAMM is 20 db or 10x the gain which would make it natural impedance around 470 ohms.
At least the feedback so far is that they work well with Koetsu and Airtight which are the two cartridges that I own.
My LAMM dealer just got back from CES so hopefully I should get the LAMM phono to try out sometimes next week.

I had an LP2 w/ a Koetsu RSP. It is not a good match.The Lamm's MC input does not have sufficient gain for the .2mv Platinum's. That said, I do bet Logenn gets great results w/ the Hommage in to the MM inputs. I sure wish I was in to SUT's back then. I would love to have tried one.

I wonder if anyone has tried Air Tight Step up transformer since it has 3 inputs with adjustable impedance. I wonder if that would match well with MM input on LAMM. There isn't much information on Air Tight SUT that I could find unfortunately.
My Koetsu is 0.3 mV, may be a tad too low for LAMM wihtout SUT.

I have used both Koetsu Rosewood Signature and Onyx Platinum cartridges with the Lamm. Both were excellent matches, especially the Onyx. There was certainly no gain problem. Although the LP input level into my preamps was lower than the CD/SACD, my last three preamps had adjustable gains for each input separate from the others. I suppose there could be an input to input level issue on preamps whose input levels are not adjustable, but most of the preamps one would use with an LP2 are (possibly not including Lamm's own preamps--I forget, I haven't had one for years). I should also add that the LP2 seems very forgiving on record noise, and I was told by a dealer who seemed to know what he was talking about (not the one I bought the LP2 from) that sometimes a higher output level on a phono amp increases the perception of surface noise. Why that should be is beyond me, but I at least mention it.

Hi Sut

Another phono stage you can consider is the EAR88b. I heard it a few times and auditioned in my system. Its very good as well.
Not as dark as the lamm but just as refined and have some loading options & gain control.
It works well with the Koetsu & you can use it with stepup if you want as well.
