We have recently released Ember 2.1. Before you panic and think your Ember 2 is obsolete, don't! The change was minor. In short, we changed up the input jumper configuration to offer a couple more options with almost the same amount of pins (Fran's clever dice jumper layout).

Now let me explain why we made this change. We recently added a resistor to the whole product lineup that further killed scratch in the volpot as certain tubes / random tubes had micro levels of leakage that were higher than others. This could cause scratch even with the input caps in-line. This resistor further eliminated this and took it to the next level. However it had a side effect on a handful of tubes such as 12at7's or 12ax7's that could be heard in high efficiency IEM's. The result was a slight but noticeable increase in background hiss. (The joys of being compatible with such a wide variety of tubes HA!) So Fran's suggested a simple but effective 4 way dice jumper to give our customers more options on the input side with Ember for micro tweaking capability. Thanks to a great customer Eric for helping spot the combination of things that increased hiss with his IEM's)
 
Before: You could either have the input capacitor in-line or bypass it. Many Audiophiles like this better even though it can cause a scratchy sound in the volpot as a micro amount of DC makes it through

Now, we have 4 total settings:

Oh man that sounds so complicated, what do I do? HA! It is actually simple as it gets like most of our settings. Changes can be made in REAL time while listening to music or background levels. Literally move a pair of jumpers and listen to the change or lack of change. If you like it better, leave it. If you like it less, change it back. Yes, life can be that simple! As with ALL settings on our designs. There is virtually NO right or wrong. Just what sounds best to your ears and THAT is what matters.
