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,
X

Thanks for the responses. I will do some further listening today to decided if I can live with the 840C's shortfalls in the context of my system.

Mapman (or anyone who owns the Havana) do you find it has just a warm/musical character, or would you also describe it as dark in any way? The former would be great with both headphones; being dark though may not be too synergystic with the HD650.

The Paradisea is definitely warm and musical, not dark in any way, with either stock GE tube or Tung Sol equivalent that I have used.

I use it sourced from both my Denon player/recorder and Roku Soundbridge.

Can't speak for the Havana having never heard it but from what I've read and been told by others, the consensus seems to be it sounds similar but improves marginally on the Paradisea's sound.

When I've heard the 840c on a very good dealer reference system, it too was very musical.

The Paradisea may be a touch warmer but not by much if so.

The Paradisea with Tung Sol tube and the 840c sound more similar than not as I recall. With the stock GE tube in the Paradisea, the midrange is perhaps more warm and lush and the overall dynamics are probably not as good, but are still good enough that you might not care.

Xenithon and Dtc,

It would seem we are all hearing pretty much the same thing on the 840C. X, please keep us posted on your progress.

Havana ordered, arrived, and within 20 minutes developed a loud hissing/crackling in one channel. I contact MHDT - they say it is likely a faulty PCM56P chip (not the first time they found this). Sending it back to them for a refund - do no want to risk it again especially with the cost of shipping back/forth internationally.

I still have the 840C as an option - I wonder if rolling in some different (warmer/smoother) tubes into my amp may alleviate the hint of sheen in the Cambridge?

Xenithon,

I found that tube rolling with my integrated amp resulted in fine tuning the overall system sound much more than adding the Havana did. Based on your recent experience, go with the 840C and roll some tubes in your amp. I am sure you will find the results pleasing.
