I own the Lampizator Amber II. It is tubed rectified and also has the super clocks installed. It is gorgeous sounding and is "far better - different league" than the PS Audio MKII, Auralic Vega and Exogal Comet with external power supply I have owned. I believe it replaced the Lampizator 4 and Lampizator 5 models. I have audio friends who own much more expensive DACs from well known high end companies and it does not take a back seat. As mentioned above no one DAC will please every one.
