Lampizator Amber 3

You’ll love it the way it is. Then after some time get a couple of the tubes mentioned as replacements in for a try. In my Atlantic, even the rectifier tube can yield markedly improved presentation changes. But better heard once you are familiar with the unit.  

Does anyone know if the circuit in the Amber benefits from (or requires) the output tubes with matched dual triodes? I'm assuming it does since it uses two different dual triode tubes for left and right channels.

The Lampizator North America website says the Amber 3 uses ECC99 and ECC82 tubes. Beyond that I know nothing but have queried Lampizator about how many of each. One photo I saw looked like three different tubes but I don't know if it was the final production model of the Amber 3. 

My understanding is in Amber 3 the Ecc99 is used in the gain stage, Ecc82 in the buffer stage, and the third tube is a 6X5 used in the rectification stage. In my Amber 1, they use Ecc81 in the gain stage. Other tubes are the same.
In my unit they had affixed labels showing the date codes in two places on the chassis, over the cover and the bottom plate, so removing the cover would break the labels. You should check with them before attempting to remove the cover to access the tubes since breaking the labels might void the warranty.
As others said, you should listen to the DAC and let it settle in before even considering replacement tubes. You will most probably keep it as is. No harm in getting an aftermarket power cord, of course.
Let us know how you like it.

Thank You All,
I tend to get a little over eager when anticipating a new component. After each read I was reminded of James Tanner's (Bryston) quote by his name on Audiocircle "Demo is Everything!".

For convenience I will provide Fred Ainsley's (Lampizator NA) response to a similar thread on Audiocircle: 
"We don't really encourage tube rolling in the Amber and certainly don't encourage the modification of our units. While you may be able to alter things in a way that you personally prefer, we believe the Amber to be voiced very well from the get go, shipping with quality tubes.

It is also difficult to support the opening of a sealed chassis without clearing it with us. This is unlike our "tube rollers paradise" or DHT series with external tube access.

I'd encourage you to give it a listen stick and contact us directly if there are tube issues or concerns.
Best,
Fred A."

Anybody know what a "listen stick" is?
