    It is a headphone amp I use with my Iridium. I have been a/b'ing HP's direct into the Irodium vs the DV. Overal volume is the same. Best way for me to describe the differrence is like a vintage DR vs TMDR videos I have listened top on youtube.

    The amp is unneccessary but adds a little tube goodness IMHO.

    The amp has no output transformer. It uses a 6SN7 preamp tube and a 6AS7 (edited, thanks printer2) power tube. The website list a slew of other tubes that will work with it.

    A 6SA7 is a radio Pentagrid-Converter. 6AS7 perhaps?

    Next day, such sweet sound... Iridium "round" amp, 1X12 going into the DV... sounds like the vintage SFDR (sweetest amp I ever heard, didn't have the cash) played years ago.

    That said, the amp has quirks. The indicator LED is intermittent but, the sound quality makes up for it.

    I got it from Apos Audio. They gave me free shipping. Don't trust DHL's tracking info.

    Here is a gut shot from the web...

    I think anyone who hears improvement in tone when making slight changes in something will really appreciate using a tube headphone amploifier with the Iridium. As the amp burns in, the tone gets better. I am leaving it on over 12 hours a day, I play about 6 of those.

    My nephew played while his girlfrien listened. She knows nothing sabout amps but, could hear the difference. She said there was a big difference and that the tube amp sounded much better. So, it's not just me... Iridium into a tube headphone amp is killer.
