Most definitely yes. They are a pain to do, but I need to select a few standardized points (not to many.) I am open to suggestions though. Here are my thoughts - in terms of priority:
- 50Hz single tone
- 6000/7000 two-tone
- 500/3300 two-tone
Mh, sorry for deing so demanding purrin, but would it be possible to measure the T1 again, this time with an output impedance of 100 or 120 Ohm via a stick-inbetween-adapter or something? Beyer's own A1 has that output impedance, curious to see what effect it has on FR and the rest. This reminds me, what kind of source are you using for the measurements, anyway?
I sent the T1s back. I can calculate approximate results (assuming output Z of 120ohms and based on Tyll's existing T1 impedance graphs) in my head for you: +2db at 100Hz.
