Yes- Great phono stage. As Vlad states, you should be fine with the Lyra's. If you ever drop down to 0.4 ohm or below, then an SUT would make sense.

actually.. My Kleos Sl is .25mv

I ran a Koetsu, and also a Low output Benz in to an LP2 some years
ago. I think it lacked a sort of dynamic jump factor w/ them. I can't speak for your Lyra, and it's .25 mv rating. What I can say is, I wish I tried an SUT at that time. When I heard a .6 mv Shelter at my dealers, it was a nice match w/ the Lamm. |

Can anyone tell me the orientation of the fuse? Current runs toward the edge of chassis or center? Thanks, came with a hifi fuse and I didn't notice it had a polarity until it was too late. Also I just got some 417a's, I know they should improve on the Amperex 5842 in there now, but I was curious about changing the rectifier tube. I know it converts ac to dc and can limit current in amps, but a phono pre I think would have very low current draw. Anyone hear changes in a phono pre when changing rectifiers? Thanks

I put in the WE417A's, wow they are impressive. Much better bass, and space, maybe more noise but still crazy quiet.

That wasn't a problem from the internal gain (59.5dB) of the LP2, that was a problem (not perfect matching) from the output LP2 into input Preamp (the signal into Pre got weak and needed another amplification, but lost is lost)....some compensate this his a stronger cartridge but it is a compensation. Seems it works great with 0.25mV (also my experience with it) and the Naim Preamp.With the right Preamp match even 0.20mV MC's are no problem. The LP2 is done very well. True in tone, soundstage and holographic body... much too cheap compared to other Phonostages when you look for the real thing reproduction :-) |

I have been rolling some 6X4's in my phono pre. One single FW rectifier tube. It came with an amperex from the 70's, I rolled in a GE from '52 NOS, everything just seemed better. The amperex had detail, but it was like being at a museum, no groove, didn't rock. The Ge's were spacious, just huge soundstage, slightly more noise than the amperexs, but damn quiet. Being shocked at the difference a rectifier tube( a****indiode!) had on the sound, I ordered a bunch more tubes, the ge was bought just to have a backup in house. I picked up a sylvania in a yellow box, cant find the date code, I rolled that in last week. Wow!! The difference was startling. The vocals are much more present and "thick", the bass is way deeper, and this is not hyperbole , I am talking resonances where there never were any at the same volume level. The sound stage is a bit smaller, but still big, it seems to be quieter than the GE. It really rocks though, it just presents music with more of that x-factor that keeps you engaged. I have 2 RCA's and another 2 GE's to try, it is really startling the difference in sound between these tubes. It seems when I changed 6922/7308's in my Chinook the differences were much more subtle, though I was comparing very high grade tubes and my system is much more revealing with the Lamm. Looking for advice and recommendations

I am a LP2 user for approx 3 years.
My observations based on my experience for any other owners or potential buyers is as follows; . The Jensen 31dB SUT which is optional through Lamm or available aftermarket is a must if you intend using cartridges with 0.4mV or lower output. It makes a big difference in dynamics. Trying to address what is lost in the phono by increasing the gain or volume on a separate preamp is not the same has having the higher output SUT installed on the LP2's MC stage and feeding that to your preamp. . Changing the two 0.47uF capacitors before and after the second set of tubes to V-Cap CuTF or Duelund's or other similar cap (depending on your taste and system synergy) brings the LP2 to a whole new level. |
