Damn. It's that good to get a direct comparison to the SR007? Wow, maybe we should move this thread to the Summit Fi forum then!
Just to be clear, these headphones use a custom tweaked Fostex T50RP driver correct? Similar to the new prototype Fostex cans that has been shown off? If this is true, that means that the T50RP drivers are some of the most well designed units of all time to be able to compare to current Stax with just small tweaks made.
The SR007 is probably the most relaxing and least fatiguing headphone I've heard this side of the Orpheus. I've always wanted a closed-back headphone with those same qualities and after briefly listening to the Enigmas and talking with Luis I think the Enigmas might be it.
It is my understanding that Luis is using a proprietary driver and not the T50RP. Although Fostex's ortho designs have been the benchmark for a couple decades now, both Audeze and HiFiman took some notes from them. It's too bad that the stock T50RP is such a boring headphone.
