Thanks czarivey for the peer review and pointing out my obvious mistake. Title editing is very important. Here is hoping others will see through the gap and provide thoughtful advice, as had mapman. ;-)
Mapman, thanks for your response. I have purchased a couple different tubes to try however have not yet done so. Do not have the Tung Sol tube. I was using the MHDT in a second system and just recently inserted it into my main one. Still getting acquainted with it replacing my Bryston DAC 1 there. Initial thoughts are that I might be trading some detail for better (larger) soundstage and softer sound. The USB on the DAC 1 was for convenience, hence use of the converter. I also feel the newer MHDT DACs are likely improved in USB implementation.
I will explore this at some length prior to making any decision. Should a Havana come up used I might consider purchasing it. I am in no hurry.
