The graph that was posted here for EST50 doesn't look like most other graphs here or on other forums. Does anyone have a different graph for it? It would be good to be able to compare it to the graphs at squig.link.
It hasn't been reviewed widely yet, but I'd like to know if the graph resembles the H40 in most ways or if there are significant differences. To me, the treble looks to be quite rolled off and not extended. People claimed that the IKKO OH1 had extended treble with great resolution but instead I feel it's their biggest weakness. The LZ A6 is too bright for me, but I wouldn't want to buy something this expensive if it doesn't have clear and present treble all the way.
Which other forums?

Was it express shipping? What country are you in, if i may ask?
Yes, it was supposed to be Express Shipping. I'm in the United States. Penon has always used DHL in the past but decided to experiment with a new service through Hong Kong Post. I say it is a fail.

Wherever graphs are posted. I'm mainly talking about the way the graph line is presented. The one for the ISN EST50 in this forum is way too flat compared to how other graphs look so it's not on the same scale. There should be a consensus on which scale to use when you publish graphs, at least at a forum like this, so all graphs can be compared.

You guys should get your EST50s soon. looking forward to what you all have to say. Please keep in mind that both the dynamic driver and the ESTs need burn in. I would not take the open box sound seriously. As I always find some folks that do.

Without knowing what graph setup they use, you cant use it to compare with another graph on another setup anyway.

Do all the databases at squig.link use the same software? They do look the same to me.

Squig does use the same software, but we dont necessarily use the same hardware.

For example, we could be using different amps for the output (transducer) and different inputs for the IEC711 (soundcard or dongles + adapters).

I bought my EST50 On June 23rd, and it hasn't arrived yet. But since Penon sent it through the Hong Kong Post, the shipment status is not updated, and I don't know anything about it.
I bought mine a week after you and I have not yet received them. The last tracking status is:

16-07-2021 11:30UNITED STATESParcel arrived to courier processing facility

Not sure where it goes from there.
