Gents:
I have owned a Zodiac+ DAC with and used it with the standard switching power supply since early this year. Antelope introduced the Zodiac Gold DAC and Voltikus Linear Power Supply this spring. Shane, our local HiFi Dealer allowed me to borrow the Voltikus Power Supply yesterday to evaluate with the Zodiac+. The Zodiac+ with the standard switching power supply is extremely detailed but just a little lean in the midrange when connected direct to the amp (my preferred connection). When I first connected the Voltikus, after listening for awhile this morning with the stock power supply, I just went "Oh Wow." The music exhibited a warmer, tube-like, presentation and was extremely refined. The transition was nothing short of amazing and my wife (who does not like to admit to hearing differences with audio gear) made a comment that she much preferred the sound with the Voltikus.
After experiencing the Zodiac+ with the Voltikus I have to it in my system. Shane, just thing cha ching!
