I'd like to take a moment to simply say that I am really, really enjoying my Magnum V6 right now. I know some of you have yours assembled and are thoroughly enjoying the sound but some of you are still waiting on 3d printed cups or other parts. I hope to read more impressions both good and bad soon! I've settled into my pad choice for the moment in the stretched out L-Cush. I did, however switch up my method of securing them to the cups. I cut out a couple thin strips of Creatology Foam and inserted them into the groove in the inside of the L-Cush pads. This makes them grip the cups better and stay put. I'm enjoying them more than any current production Grado, more than the HD600 and HD650, the Audioquest Nighthawk, Sennheiser Momentum, NAD Viso HP 50 and many other headphones that I've heard or owned in the past (except maybe the HD800 which is something I may explore when the discounted second hand units will pop up as a result of the HD800 S). The V6 is clear, full-bodied, and tight sounding. I've decided that this thing is going on the never sell list as it is really good at what it does. As as complimentary headphone, I have a ZMF Omni en route. I've got a good feeling about them in that they will give me "bigger" sound when I'm in the mood for it.
A recommendation I have for those of you who are still experimenting:
Experiment with pads--it makes a massive difference. If you go with the L-Cush pads, I recommend a DAC/Amp that provides some warmth and a little boost to the bottom end. If you decide to go with flats or the flat/bowl hybrid, then I recommend that you pair them with an airy/extended sounding DAC/Amp setup.
Cheers!
