I don't know anything about the particular devices you mention here. But my experience is that power supply upgrades are almost always a nice improvement. So it's not surprising that it helped with this transport.
SMSL PL200T AMAZING POWER SUPPLY UPGRADE
I had repeated issues with my Shanling ET3 remotes being extremely fragile, breaking at the slightest fall on a hard floor (a non issue for desk top users). Worse, replacements are hipping from China, in my case 3+ weeks, so I bought a SMSL PL200T, which has a USB input for an outboard power supply. I opted for a $119 iFi which was a very nice upgrade with 30 day money back from Amazon. As the free return was about to run out I saw they also have an Elite PS for $299, and curiosity got the better of me. If you can afford it go for it. Best $300 if you're serious about improving CD playback. I'll get into it later, just wanted to get this posted
