Lyra Atlas experiences


A few years ago, I invested in a Lyra Atlas cartridge / pickup. I have moved up, from Lyra Clavis in the early 2000s and Lyra Titan i later. The Atlas was expensive, but I have not looked back. Yet I wonder, can something more be done, to optimize the Atlas, in my system, and others. How can this remarkable pickup run its best. What are the best phono preamp and system matches. Should the system be rearranged. Have anyone done mods or DIYs to their systems to get the "reception" right? What happened? Comments welcome. You dont need to own a Lyra Atlas but you should have heard it, to join this discussion. Comments from the folks at Lyra are extra welcome - what is your experience.

Hi, you wrote to set AS about 2,5 to avoid dirstortion in the right channel.
What do you play when testing this? Do you use a tracking test record?

I run a VdH Frog on the SME V with AS 1.0 and on the test record the left channel begin slightly to distort about 60mµ @ 300Hz

Try to measure the antiskating mechanism like this. No really exact, but it will show you the course

Here some info from Christian Rintelen:

7. Adjust the skating force to zero and prepare yourself for
a mean experience. The right channel will not show dynamics
at all; it will sit in the corner totally bored and ignoring
you. The left channel will sit in its corner like an evil
ghost, considering to attack you in the next moment. It will
sound very dynamic in a way that numbs the left half of your
body. However, the dynamics will be nightmare-like
artificial.

Now you increase the skating force to a quarter and then to
a half of the expected value. You will sense that the right
channel comes more-and-more alive and the left channel
sounds less dynamic, intimidating and artificial. This
reduction is less than the increase of dynamics in the right
channel; the while system becomes more dynamic.

You increase now the skating compensation by *very* small
steps until you reach a point where left and right channel
sound equally dynamic. Then you increase further very small
steps; both channels will grow more dynamic. One step too
far and both channels loose their dynamics completely and
sound dead. So you go back to the position where dymics and
microdynamics were maximum.
The SMEV is a great arm, but not for a cartridge like the Atlas. The compliance is ~ 12x10 cm/dyne bei 100 Hz
You need a heavier arm to get best results. I had a Kleos in an Origin Live Conqueror with 18gramm eff. mass and in a Reed 3P with the same mass.

The SMEV is a great combination with Van den Hull cartridges.
All theory, after repairing in Japan my Kleos had a very high compliance and my bass speakers made synchron movements to the out of center vinyl.
