MHDT Orchid or Lampizator Amber 3?

Greetings Bob and All -
Wonderful thread with lots of useful perspectives. I've had my Orchid for a couple of weeks and love it. It sounds a lot better now than it did when it started out and seems to take about 30-45 minutes before it really sounds great. 
Here are some questions to those who own Orchids and have been tweaking them.

1. What tubes have you rolled and what have you ended up preferring?

2. Have you upgraded the stock TDA1541A chip? If so, to what version?

3. What capacitors etc have you replaced?

4. Is anyone using a USB decrapifier like the Schiit Eitr?
5. What USB cable are you using?
Thanks all -
Markus

I take it when you get the volume control on the Amber, then you get a remote and input switching? 

What is the price for that option?

And lamp. does not do i2s inputs, right (that's one factor that pushed me towards the audio mirror)? 

I would just like to add my thanks to all you gentlemen for the most excellent sharing of curiosity and experience in this very informative thread.  
I’ve had this little Orchid DAC for a few months now and simply love it.  It sounds so nice and sweet - almost as good as my record player.  Almost....

I’ve been dreading shopping in the minefield of new DACs but this discussion has provided me with needed direction, and I thank you guys for that!  Hope the stateside Lampi team will be participating in the Florida Audio Expo In Feb......

No need to change out the chip in the Orchid. Folks who have and then compared to a fully burned in stock chip now say the stock chip is great.
Output caps can be Jupiter copper foil, Miflex 1uf, Audience XO or the new Vcap ODAM

The Western Electric tube is a must do upgrade. A good fuse helps.
The resistors around the tube can be upgraded to the Vishay Zfoil with great results. Contact me for values if interested and serious about doing the upgrade. Need to be skilled at mods and  working on the circuit board.
