Great hear Bart-its a great cartridge for sure 
After living with it at 100 ohms, try bumping down the resistance to around 200- you might like how that opens up the top end a bit. JRâs shim also brings down the VTA ( at stylus position vs arm position ) as close as possible to reach the ideal 18 degrees. Just need to level the arm first and you are good to go!
For z-foil airplugs I have 100, 400, and 453. Thereâs a 220R non-airplug that came with the SuperLine however.
If you use both the 400 and 453 together (utilizing the capacitance socket), you will get 212Ω
The math is: 1/(1/R1+1/R2) = R3
This is how you can get to about 220R with your Airplugs. You wonât hear a difference between 212 and 220.

When I had a Superline I tried my Lyra Atlas at 100Ω and 220Ω and thought it sounded a bit sluggish (soft bass and lacking liveness) by comparison to the 470 I settled on. With my Boulder I use 600 and 750 for the stereo/mono Lyra Atlasâ respectively.
Bart has heard this from me, but repeated for othersâ benefit.

The treble is a bit TOO lively right now on many LPs but I can blame it almost entirely on my very lively room. Oh well!

Try adding a bit more weight to the cartridge as in tracking force, this will tone it down a bit

The Etna has a rather narrow range â 1.62-1.72gr â that one shouldnât exceed, especially with the Lyra because of the design of the âNew Angleâ suspension. I track my Atlas at 1.65-1.67 gr. I have never noticed increased VTF toning anything down with it, but it does impact performance.
Normally running a cartridge lighter will bring out the higher end more and slightly less base, doing the opposite dies the opposite.
I run my own cartridge above its recommend maximum tracking force as i prefer it and it certainly makes a difference how much weight you run it at
But it degrades quicker the cart.
Does the Aro 2 not like a little extra downforce? With my Aro 1 it was my dealer and a few others said that because of the Aroâs design it always liked a bit more force. Linn recommend 1.8g for the Krystal but 2.0g sounds perfect to me with the Aro 1.

And it can damage the Lyra, due to their uniquely designed suspension.
The U.S. distributor for Lyra and I have talked many times. He is adamant about not exceeding rated VTF. Joe Harley has said the same to me. He was a VP at AudioQuest when they were the Lyra U.S. distributor and has a lot of experience with it (he uses the Atlas stereo and mono cartridges for his professional work).

Well if you cannot add a bit more weight it sounds like this cartridge isnât for you then.
As if it sounds too bright then you either have to live with it, sell it, or try to get it sounding how you want it.
If that means that you get to enjoy the music, but a bit less , that is better i feel than not enjoying it at all ?
But thats me.
Itâs just fine for me. I run my Lyra at 1.65 gr., within the range limits.
Bart is the one trying to tame it, but thatâs because his room is overly bright with hardwood floors and lots of glass. He cannot use area rugs or other treatments for unrelated reasons. But he should not run his Lyra Etna over the recommended VTF range. He knows that already.
What cartridge are you using @Dunc, because it sounds like you are just generalizing based on what you have and like? Thatâs not always valid or going to result in the same affects.
Lyraâs recommended range is 1.68 to 1.78. Iâm not exactly sure how many of these strain gauge based scales are accurate to that second digit after the decimal point.
No, double check your manual: the range is 1.62 - 1.72g. Somewhere in the middle probably works pretty well. I use 1.65-1.67 or so. Joe Harley told me he tracks at 1.65 gr. Please ignore people who tell you to go over the range. Forget all their arguments about it. They arenât going to help you out when the suspension fails prematurely, and Lyra says too bad so sad. They arenât the experts. Lyra is when it comes to their own.
Just get yourself one of these Riverstone gauges from Amazon, use the record level platform with it, and push the reset button each time you check. For $35 it works really pretty well. This is what I use on my $100k turntable setup.
I have a Riverstone gauge; my strong guess is that itâs the same strain gauge inside the case, but the geometry of the thing you put the stylus on is better such that itâs actually at record height.
I also have a pretty expensive Rega gauge, the gauge that came with the Solstice . . . they multiply like bunnies!
Bart, I also have the Rega Atlas stylus gauge, which costs nearly 10x as much. I got it as a gift. It works well enough, but I like that the Riverstone measures with the stylus at about record height, whereas the Rega measures at about twice as high.
You really want to measure as close to record height as you can, although I suppose if you take that mat off that Stelly gave you, and place the Rega directly on the platter, that will likely be a more optimal way to measure.
No reply here from the OP. I wonder how they have resolved their issue with the tonearm?
