I have also heard rave reviews for these but have never seen one..

At the other end of the scale, I recently bought a Tubemagic D2 from maverick audio, I can't believe how good this is for the money, got to audition a cambridge audio dacmagic before this but wasn't that impressed with it so I took a chance with the D2 and I'm so glad I took that chance. It's got plenty of inputs, optical, S/P DIF, USB and BNC/coaxial, all support 24bit/96khz and two out puts a solid state and a tube pre-amp out .

First of all I was using the solid state which had a nice crisp sound and quite punchy mainly cause I wasn't overly impressed with the tube out,after about a month or so I decided to give the tube another go and now that's all I'm using, the sound stage seemed wider and deeper and more natural than I recalled and it just seemed more natural and non fatiguing.

You should definitely consider reviewing the tubemagic d2 as I found it hard to find a review of it and it has made a massive improvement to my entry level set up.

Cheers.
