My experience is limited but I have a little experience with the MHDT DACs. I have the Pagoda (non-balanced) and I really like it but I prefer my Chord Qutest. The Qutest has better bass and treble extension, and better detail. The Pagoda definitely is more of an analog and less fatiguing sound, but in my opinion, it's not as true to the source as the Qutest. My good friend got an Orchid on my recommendation and I'm afraid to say, neither of us liked it very much. It was much more rolled off than the Pagoda in bass and treble and it overemphasized certain frequencies to a strange degree. For example, any recording with tape hiss was almost unlistenable because of how the DAC emphasized it. We thought it was defective but he returned it and the folks at LTA said it was working perfectly. If you decide to go MHDT, I would go for the Pagoda, especially if your system is a bit on the analytical side. If you already have some warmth, I might suggest staying away from tube DACs
Did you or your friend use the factory supplied tube(s) or change them? What you mention can occur if sub-standard tubes are used.
Several friends with both MHDT Orchids and Pagoda, all good luck so far past 3-5 years. Mine is dead quiet. Both DACs sound different and better with really good tubes. With really good interconnects and for the DIY'ers, adding top-shelf coupling caps open them up even more but still retain the R-2R Ladder non-oversampling (NOS) analog type of sound.
