MHDT Orchid or Lampizator Amber 3?

To answer Butlers post, Yes Lampizator North America will be a the Florida Audio Show in Feb 7-9th.

We will have two rooms. Duplicating the Capital Audiofest room that was considered one of the best in show. Amber 3 DAC, Spatial and Linear tube audio. Just under 10k for the system too. The Amber 3 will be for sale as a demo deal.

We are also doing a high end room with Vac, Daedalus and will have a brand new balanced Pacific and our SuperKomputer for transport duties. The Pacific and SK have already been spoken for.

Hope to see you some folks from Agon there. It's a fun show, and of course the weather beats most places in Feb.

Rob, from the pictures of the Amber 3 it looks like the case is a sealed enclosure, what is involved with changing the tubes either due to tube failure or desire to tube roll? Does the unit have to be shipped somewhere for service? 

@facten 

Since the Amber 3 is a sealed design we don't encourage tube rolling. If careful the case can be opened, and the tubes can easily be changed. If you're concerned about damaging the unit and or electrical shock, please have an experienced tech replace the tubes. We have two techs we use for service/warranty repair, one on each coast. 

With all due respect to the Lampizator team, the case is similar to a great many cases: to remove the cover one only need remove a few screws (hex) and I'm sure it slides off to reveal the inner workings. There are a couple of seals which would be broken if you did remove the cover, which might void the warranty if you did so (I emphatically have not!).

Now, if I wanted to tube roll some 12au7's etc, it would take something pretty spectacular to better the sound. Flavor the sound? Yes, I'm sure it would be possible but to significantly better the sound by rolling in some NOS tubes would be highly subjective. I haven't felt the need to tube roll the one I have but I wouldn't hesitate if I believed it "needed" it or there was some sort of deficiency/correction that could be influenced by tube rolling.

As is always the case, listen to your manufacturer if they provide guidance, especially if by not following said guidance it would void the warranty.  I just didn't want the community to believe that future tube maintenance was going to require a trip back to the manufacturer in Poland and the answer is no. Recognize that manufacturers and their role in promoting safety/operability and long term reliability are best served by advising against opening the unit.

I just wanted to make sure the audiogon community wasn't under the impression that the case is sealed, as in impossible to open, versus advising the user base to seek out an audio professional before "fixing" the Amber 3. Peace to all.

In short, if you want to risk voiding your warranty, the Amber 3 can be opened just like other equipment you may have.The difference being that by breaking the seals, there is no turning back.

Well, I have 2 DACs - Modwright and Aqua and the cases have several  hex screws on the casing itself to make it easy to remove; the Amber looks like the screws are only on the faceplate. So if I follow you  if a tube goes bad while the unit is under warranty and you don't want to incur shipping for something as easy as replacing a tube it sounds like you will invalidate the warranty because of 'broken seals".  I don't get the logic to this setup
