First and foremost big shoutouts to The Source AV and in particular
@TSAVJason and his crew for hosting the event! To Cavalli
@warrenpchi and
@Stillhart and Questyle
@bSquared64 and
@mikemercer!
The HD800 and the HD800S on both the questyle and cavalli setups sounded wonderful so picking a favorite between the 2 was tricky. In the end after flip flopping between the 2 I would say my personal preference was the HD800S though the original HD800 was a more interesting can.

Wonderful track I heard from Mercer's suggestion! Loved it!
And then as it got a tad busy went to different part to listen to some awesome setups with all the cans and rigs The Source had!

Wow wow the th-900 are some lovely and bassy headphones, thanks
@Bones1885 for giving me a chance to hear your cans~
Then
@moedawg140 showed up and I whipped out a few of my iems I brought along with my cans...

Then we had an impromptu little meetup! Lots folks floated by, we talked and joked a lot, heard a lot of gear from moe! And I got to hear the new Hifiman He-350 moe brought....

$99 open back dynamic from hifiman and massdrop? Personally as a big hifiman planar guy hearing this dynamic open back was in my opinion nice. For the price and the clarity it is nice contender for probably the best value can at $99. As it is stock pads and through my fiio x5 my first desire like with a lot of my headphones was to try it with an amp so I hooked it up with my Topping X1 amp and we got a nice improvement to the bass. Treble I found in a bit bright.
After listening to it stock and passing it around so others could listen to it I decided to take my angled brainwavz pads and put them on the headphones and holy moly we got an improvement to the bass! For the treble I did some experiments with some paper towels and tried adding some to tame the treble, initially 4 pieces was a touch too veiled, 1 piece seemed like it was what most people preferred! Did a little quarter size hole mod and that wasn't as well received. So overall with like most hifiman cans modding was a lot of fun and simple!
I had a wonderful time at the event and I look very much forward to the future events! The Source Av is a great location or I even daresay probably the best location in SoCal for a store with headphones~ Jason is a wonderful man who ordered us a delicious lunch and after the event when we went to dinner he was very very hyped about the next events and kept teasing to us the headphones premiere next month... Still very curious about it...
