I love this reference from the Torii owners manual:
"You can't spend enough money on a source to hear how good the amplifier actually is, so each time you upgrade your source the amp will blow your mind all over again."
This is 100 percent true!
I upgraded my source with the Audiophilleo 2 + PurePower. I am feeding it with a SBT + EDO into an Anedio D2 Dac which is feeding my beloved Decware Torii MKIII and Zu Soul Superfly's.
There is an excellant Audiophilleo thread on HeadFi where I posted my briefimpressions:
