I have the 400 and the 400i. will be sending the 400i back. Now looking at the audeze. So the model is LCD-2.. But ive seen the word Fazor and 2.2 and others. A little confusing on their model ect. So which is a good one to google thx.. I prefer a good bass. Prefer one than can be driven by the asgard 2 and maybe a fiio e12.
All the revisions can be confusing if you are just starting to look at them now. The first major change to LCD2 was the second revision drivers. These are referred to as LCD-2.2 or LCD-2 rev 2. These have newer drivers than the original rev 1s that have a little more extension in the highs and the lows. The impedance also went from 50 ohms for rev 1 to 60 ohms for rev 2. You can't always tell a rev 2 from a rev 1 just from the looks. The rev 1 had a foam headband that was replaced with a nicer looking, but less comfortable leather headband in the rev 2.
The next changes that came along were cosmetic/structural and don't affect the sound quality at all. The wooden connectors were replaced with more sturdy metal connectors. Around this time they also introduced the bamboo version. All versions with wooden connectors are rosewood, as there was no bamboo options. I have seen some people refer to these as "rev 3", but I don't think that ever really caught on since they still use the same rev 2 drivers.
The latest change is the fazors. These are referred to as LCD-2.2 F, LCD-2 Fazor, or something like that. The fazor is supposed to improve the soundstage/imaging and rolls off the extreme low frequency and improve the highs (correct me if I'm wrong here). Don't be afraid of weak bass though, I think people say the roll-off is below audible level (once again correct me if I'm wrong, never heard the fazor version). These drivers are now 70 ohm impedance and more sensitive than the non-fazor rev 2 drivers.
I hope I didn't miss anything, but these are most of the changes that I am familiar with. There were some changes I didn't mention to the rev 1 grills, but I have never seen a pair with the original grills for sale here.
