If it hadn't been for this thread - thanks nice-biscuit! - my maxed-out Supermacro (opa627) and Supermini would still be languishing in that draw under my desk. But no more! Re-charging and putting in those Enloops in both amps, hooking them up to an iPod Classic (lossless) > ALO CLAS and listening with Beyer's DT 1350s and Hifiman HE-500 (no, not at the same time!), I'm simply amazed at how a technology used back in 2006 and 2007 has such a wonderful presentation today. My comparisons are with the Pico Slim and ALO Continental V2 and Xin's two amps still hold their own. Next up will be using Xin's amps with the JH13s.
As mrarroyo so rightly says the Supermacro affords real flexibility in addition to the sound. Xin was so far ahead with his "It's ABC!" some 5-6 years ago and the options that afforded with different headphones. Given what I am hearing makes me wonder what the amps he would have built today would have sounded like. I am simply amazed at how good these two amps sound. And, yes, the Supermini can indeed drive the HE-500s! That tiny little amp in a blue plastic box!!! Makes you wonder....
Is there a portable amps hall of fame??? Xin would be in it!
I hope he's all right. Anyone hear from him?
