Lampizator Amber - moving up the range?


Hey all,

I have a Lampizator Amber plus. I've managed to get massive improvements to it by putting rare NOS valves in. Really liking this piece of kit. I feed it with an Auralic Aries streaming Tidal. 

What are the higher range Lampizators like? Would I see a small or large improvement from upgrading?

Thanks, Tim

Adding tubes to the output stage of a DAC is contrary to ACCURATE sound quality! It is stupid to seek a euphoric coloration this way - rather than accepting the linearity of a well-designed SS DAC! 
Tubes are most linear on initial turn-on. They only degrade over time. Unlike, say, whiskey, tubes DO NOT improve with use! To believe otherwise is to be delusional. And I own a considerable collection of tube gear!
So I assume this is a dislike of valves Rob? I didn't "add" valves to the outputs stage, the unit is designed with them.
