kaka Posted November 6, 2010 Share Posted November 6, 2010 I saw a mention somewhere of Sonic Studio showing a new power supply at RMAF (I don't think it shows on their website yet). Did anyone get to do a A/B comparison with the stock supply at the show?

sjohnson Posted February 13, 2011 Share Posted February 13, 2011 The Sonic Studio website now shows a PS accessory for the SS Model 4 - (copied into subject line). Haven't been able to find any more information on price, specs, etc yet. Link to comment
bordin Posted February 15, 2011 Share Posted February 15, 2011 If I'm not mistaken, old Metric Halo ULN models require external power supply. For playback, the new models can be Firewire-powered. Sonics of my ULN-2 either Firewire-powered or adapter-powered is very good. It would be better in terms of the investment/performance gain to improve other components on the signal paths instead such as the interconnect cables. Nonetheless, decent cables could cost more than the RMAF adapter. Link to comment
Purite Audio Posted February 15, 2011 Share Posted February 15, 2011 I commissioned a linear power supply for the Model4/5 I expected it to make a difference, it didn't! I guess the MH/Amarra dacs are well designed and implemented. Keith. Link to comment
sjohnson Posted February 15, 2011 Share Posted February 15, 2011 to see what the option is and how much if any difference it would make. It would have to make a noticeable difference before I would consider purchasing. I do wonder if taking a switch mode ps off of my electrical system for the sound room would be worth it or not. On the other hand there are options for isolating the dac and the computer more than just what I get with separate dedicated AC runs. The Model 4 seems to be the least affected by power cords of any of my gear. And whenever I look at that switch mode ps block without an expensive power cord while happily listening to the music I'm a bit amazed at the overall performance it is capable of. So, yes good point, the design and implementation does seem to be well done. More $ left for music and less fiddling around with equipment is a good thing. And with more enjoyment of the music my mind analyzes the system less but doesn't let go completely as I think that is part of the fun too, but anyway I digress... Best Regards, Steve Link to comment
Purite Audio Posted February 15, 2011 Share Posted February 15, 2011 Just to add, the fact that IMHO the power supply didn't improve the SQ of the Model 5 isn't intended as a criticism of the power supply, more an affirmation of the design quality of the Model 4/5. Keith. Link to comment
