In my case I use a Zhaolu D3 with great results. The opAmp in mine were not Lt-1057 but Lt-1028. The 1028 are single type opAmp. I replaced them with BurrBrown opa627 with greater results !
And I am waiting to receive Burson 'discrete components' module that will replace the opa627 ... -- Acme ------------------------------------------------------------------------ Acme's Profile: http://forums.slimdevices.com/member.php?userid=13875 View this thread: http://forums.slimdevices.com/showthread.php?t=39892 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
