Noticed that there hasn't been anything posted on the Audeze LCD-3 for some time now. The Fazor update was around 2014 or so, and there was a fair amount of press at the time that it improved the performance of the headphones.
I picked up a set of LCD-3's last fall, and to me, they sounded pretty darn good overall. I found it a step up from a pair of Focal Elars that I was using. At this time, was using a Mjolnir Audio Dynalo amp to drive the Audeze LCD-3's. While I was happy with the sound overall, noticed that some recordings didn't have quite the clarity I was hoping for.
So, when a deal to pick up a Mjolnir Audio Pure Bipolar for a really good price came up, decided to pull the trigger to see how it drove the LCD-3's. Turns out that the Pure Bipolar is a excellent match for the LCD-3's. The increased clarity I was hoping for was there now in spades. The improvement provided by the amp was quite noticeable.
The questions I have for the group is: How many LCD-3 owners upgraded to the LCD-4? I did read that there were a number of failures with early LCD-4's, which has supposedly been corrected. For those that upgraded: Was the upgrade worth the extra expense?
