840C and MHDT Havana


Hi all. I wanted to ask if anyone has had experience with both the Cambridge Audio 840C and the MHDT Havana DAC. I will primarily be using these playing lossless files through my Macbook, and using a fairly warm but dynamic OTL tube amp. I can get these for around the same price (Havana new, 840C used).

I am particularly sensitive in the HF region so am a little weary of comments I have read about the 840C's "digital sheen" / brightness; though some have said that 200h+ helps smooth that out (not sure to what extent and if the brighness is an inherent trait). The NOS, filterless, opampless design of the Havana appeals to me to from a purist and musicality perspective. I wonder if these two essentially play in the same sonic league, albeit with very different presentations.

Cheers,

I have an MHDT Paradisea and have been very pleased with the tube DAC sound in my system so far.

Assuming the Havana behaves similarly to the Paradisea, one advantage of the mhdt tube DACs is that you can tweak the sound inexpensively if desired using different tube equivalents.

For example, using the stock GE tube produces a more "tubey" sound in the midrange, very enticing and enjoyable, but some might also say somewhat colored (in a good way).

Using the Tung Sol tube equivalent, the sound is more indistinguishable from SS equivalents I have heard. There is more overall dynamic impact and less coloration through the midrange, I believe.

Noise levels have not been a factor in my system using the Paradisea, but I suspect the Cambridge SS unit and perhaps even the Havana may be better in this regard, which could be more of a factor in some systems, for example those using highly sensitive horn drivers in the speaks for instance.
X,

I have the MHDT Havana for Home Cinema setup.

For the "fun" I compared the Havana to my Reimyo CDP-777, connecting the Havana using the CDP-777 drive (output with digital RCA). All of this on my revealing system, Nagra, VAC and Magico.

Well despite its not in the same league I can comment that its is very musical smooth, highs are not aggressive, bass a bit "cotton wool". Bare in mind that this is comparing the Havana with what some (including me) consider to be the best CDP ever.

On a scale of 10 (the Reimyo being 10) I would give it 6.

I did a similar test between a Magnum Dynalab (102T) and internet radio, not bad either. At that it would be a 7, the Magnum being 10 on that scale.

I have heard solid state dacs in this price bracket and they have always come out "dry" and "agressive" to my ears. Solid state is okay in more expensive range where tube outputs stages are also present, its then a question of taste. Compare an Audio Note DAC5 with a Reimyo DAP-999 and you will like one or the other, neither of them lack anything.

Take care

I use a Cambridge 840c as a dac for apple lossless files ran through a primaluna dialogue 2 integrated tube amp. I do not experience any sheen and am very happy with the combo. Hope that helps some. I have rolled mullards into my system but ultimatly settled on tung sols 12ax7, Radiotechniques 12au7, and genelex goldline reissues Kt88. because the mullards were ultimatly to soft for my taste. Good luck
Regarding "sheen", I would expect a SS DAC to mesh better with tube amplification like in Beerad's case.

If SS amplification is used with a SS DAC, the results might be more "sheeny", but to me this is not necessarily a bad thing....its a matter of taste and preference more so than absolutes regarding one sound being better than the other. It comes back to the typical SS/tube debate scanario, I suppose. Some will prefer all tubes, some a mix of tube and SS and some SS all the way.
