I received the Glacier today and I am very impressed with the build quality it truly is a masterpiece. It is exceptionally well built and it is very slim as well, from the photos I thought that it was going to be larger in thickness and also in width. Truth be told I believe that it is almost the exact same dimensions as an iPhone 4s (my phone is in an otterbox so it is slightly longer and wider and a lot thicker than the glacier.
After it finally finished charging I decided to give it a whirl by using my EACE lod and my 4s, the sound is exceptional right out of the box and with adequate burn in I am certain that it will only get better. TTVJ and Pete have done a great job on this amp, the led's also change color depending on the volume setting it starts off all the way down with red and the color will slowly change into orange then into yellow then into green into blue and finally magenta at the 32 step. It is really a nice little light show to see my 3 year old son noticed the led's almost instantly.
The same led will blink white will charging and then stop when charging is complete. You can also change the gain from the default of 10db to 20db and then to 0db (what I am using with my Heir Audio 8a's) the same led mentioned previously will give a blink in between the volume color to green for 10db, blue for 20 and red for 0.
A lot of thought certainly went into this amp and I am certain most people will enjoy the little subtleties that sets this amp apart from others. I did not realize that the click wheel had to be pushed in in order to turn the Glacier on and off as I assumed that once you reached the lowest volume that the wheel would click and lock in the off position. The Glacier not only goes one step further by remembering where the volume was when you de-energized it and will automatically go back to that position when power is re-enabled (simply turn the click wheel slightly up or down and this feature will disable), it also turns the volume completely down before it powers off.
With all of the good there is also some things that are not as good. Even with the beautiful stainless steel exterior the Glacier is prone to RFI, while listening with my iPhone 4S sitting directly on top of the Glacier I would receive all sorts of wonderful RFI when email was received, this seems to hold true whether I am using the wifi in my house or the Verizon network, this issue can be fixed by putting your phone into airplane mode. It is really noticeable with the volume at lower levels and hard to hear when the volume is louder. With the Glacier muted and music player paused there is a slight audible hiss with my 8a's. And as others have pointed out there is a thump when powering the Glacier on or off.
As the Glacier comes with a 30 day trial period I will continue to evaluate it and I will have to decide if all of the plus's outweigh the few minus's.
