Berkeley vs Bryston vs Lampizator

Bricasti is a killer DAC. I heard it in 2 system sbefore deciding to buy one for my system. No regrets. Best DAC I've ever heard, but I've not heard every DAC. One friend however sold his Bricasti in favor of a chord DAC

I have the original Manhatten.  I guess I should contact Mytek about an upgrade but I'm so happy with it that I haven't bothered

The lampizator big 6 with;
Western electric tube rectifier. 
R2R and DSD. 
Imho the big 6 will beat all the above. The beauty of a nos dac is that you can pretty much dial the sound. As far as none fatigue, organic, 3 dimensional sound both deep and wide.  You just can't touch tubes.
