ifi micro iTube - Tube buffer/ preamp Gen1

Further Information: 

The 1st gen of iTube, 

There is modification: 
Some of the internal solid capacitors have been recapped to Audio-grade electrolytic capacitors such as Nichicon MUSE and ELNA TONEREX II (which was used in 2nd Gen iTube I think ).  

This modification makes the sound more vivid and true.

It works perfectly with my active speakers and Naim preamp as well,  I basically use it as a buffer.
There are signs of use on the case and the volume pot. Please refer to the pictures.
