Any sonic differences from the mark ii versions? Or same tuning?
Here's the FAQ from my order page:
How is the new ZMF Classic different from the original ZMF Mods?
Since the ZMF's were first introduced in 2011, we have learned a lot about what makes a headphone sound good and introduced our full line of custom planar magnetic headphones. This presented an opportunity to add this knowledge as we designed the ZMF Classic mod for the Fostex t50rp MK III. It worked...the ZMF Classic is truly an instant. Classic.
Why is the single ended jack replaced?
By replacing the stock 1/8 jack on the left earcup with a gold plated jack, any channel imbalance from a cheap connector is eliminated. Furthermore, you can now also use after-market cables with the ZMF Classic.
For the Master Model you had a V1 and V2 tuning where the V2 had more bass right?
Yes! I decided to have just one tuning for the "Classic." Now with a full line of headphones representing what the ZMF sound is, anyone familiar with our slightly bass boosted, musical and extended sound will enjoy the ZMF Classic to its full potential.
Can I get some custom paint jobs?
Unfortunately we no longer do custom paint on the Classic. It helps immesely with our turnaround time. If looking for something with a more personal touch, check out the
ZMF x Vibro MK II.
-------------
To add to this - the tuning is overall a touch more neutral than the original ZMF, more sub-bass vs mid-bass boost, but with less treble peak.
I also added a graph of the ZMF Classic VS stock t50
