MHDT Orchid or Lampizator Amber 3?

Bill, I appreciate your answered my questions. I live in Canada and there is an experienced technician here who I suppose  could make these modifications. I would like to avoid sending back and forth the unit but nonetheless I will think about your proposal as I trust your knowledge of this dac I will let you know. You can send a me message to detail what you are offering.
About the cv-181 tube, at first, like others users, you seemed exited by the sound of this tube, what changed your mind, bad tube? some report these tubes are not reliable.

I reported on the thread that over time it sounded forced and a tad bright. That tube also pulls more current than the other tubes folks are trying and I think it is pushing the limits of the small tranny. I would not use it. It pulls more current than a standard 6sn7 tube as an FYI.

That tube also pulls more current than the other tubes.


The cv181 has a heater current of .95 amps and the 6sn7 is .6 amps. Quite a few transformers were being destroyed when that tube was being sold as a 6sn7 alternate.

Good evening everyone, first post on Audiogon. 

After following this thread with great interest, I finally picked up an Orchid and have done several of the upgrades mentioned by Grannyring (and others). I am enjoying the whole process of upgrading and hearing the changes and improvement so much so that I finally decided to post on this forum to say a big "THANK YOU" to all who have contributed. 

The Orchid is a great DAC and it is easy(ish) to work on.

R38, R52, R36, R54 Vishay Z foils  0,60W 100 Ohm
R34, R58 -- Caddock MK232 0.75W 390K

Jantzan Superior Z - 2.2uf 
Duelund CAST-PIO-Sn/Cu   0.01uF 630Vdc

Really enjoying the sound now. I would be happy to live with the Orchid the way is now but I like to tinker and ask "what if I ..."

Great stuff. Great fun 

Any other upgrade/change sugguestions are welcomed.

@paulski How did the upgrades work out for you?
