$30K DAC in a $70K system - wise or ridiculous?

With the Lampizator volume option you eliminate the need for your BHK pre-amp so I think it's a great upward move. Good luck! 

A few years back I made exactly this move. Put a $25k DAC (TotalDAC) in $60k system (Luxman & Vivid). Because the DAC was precisely to my taste and beat out several other $20-$30 DACs, it was the most unregrettable move I ever made. In fact it’s the only piece I still have from that setup and has survived 2 full overhauls. So my recommendation is that if the Lampi makes music exactly how you always imagined your system would sound, go for it. If you have any doubts it’s an endgame sound, it’s too expensive a mistake. A piece at that price is only justifiable if it’s an anchor to your system.

❝This ability to present the 3D-image of a recorded vocalist like Sinatra in a startlingly realistic spatial and timbral manner was one of many initial sonic impressions of the LampizatOr Pacific Balanced DAC that, like harshly-lit craters on the lunar surface when viewed at night from Earth, stood out in bold relief to me compared to other DACs I am familiar with❞

IMHO, it is all about system match, meaning your core gears (including cables) have to be in the same level of performance capabilities. Honestly I felt the $25k DAC is too much an overkill to your other setups. I would match the Pacifica DAC with some top notch cd transport like Esoteric P-0s and top range digital cable. Just my two cents here.

Totaldac is beeig destroyed on asr for mesuring poorly compared to 300$ dacs and having less build quality than the average diy product...

If you like the sound of your 25k Totaldac, that is fine. But please don’t tell us it is a good value in the audiophile world...it is very far from being that... I would not call it a good value even in a 300k system...
