Cambridge Audio DacMagic Plus Power Supply Question

Lots of options depending on the budget, just make sure its 12V @ 2A with a compatible size plug. 

My problem is just what is the barrel size to be used with a DacMagic PLUS if I get a new 12v LPS? My old Pangea P-100 barrel does not fit the new unit and is now a paper weight. Thanks to all!

I just changed to this:  iFi iPower Low Noise DC Power Supply with International Travel Adapters 12V

I also had to buy  SoulBay 34pcs Universal Laptop Notebook Input DC Plug Set Jack Tips because the tips with the IFI did not fit. So it cost me 62.00 total and I do notice it's cleaner and allows me to play louder without the congestion I heard often before. I played Seagul by Bad Company to test because I know the song so well. The background is blacker for sure to my ears.

System is Rogue SPHYNX v3,  Cambridge - DACMagic 100, Oppo BDP 93, ROTEL RDV 985 and Focal Chorus 706 speakers

Those iFi units are quite good for their price. I think you’d have to step up to something much more substantial to beat it. I’ve had good luck with them powering my DACMagic Plus, tube preamps, miniDSPs, etc.

To answer your question YES - a better power supply will definitely improve the performance.  The sBooster made a noticeable increase in SQ in my system  -increased bass, soundstage and imaging were immediately noticed, along with increased clarity in vocals ( words to well known songs that had been uncertain before were now becoming recognizable). I got mine from Upscale Audio here in California, ~ $400. I had reservations about spending $400 on a dac that cost $550 when new, but not after it was in my system. Try it out, Upscale offers a return policy if you are not satisfied. Order it specifically for the DacMagic Plus and it will come with the necessary adapter. 

My system: Sony C222ES to DacMagic to Rogue Pharaoh to Martin Logan Montis via Black Cat coax, Darwin Ascension + and Goertz Veracity cabling, respectively
