What a fellowship of harmony it is! These discrete designs from Orange Amp just BARELY fit side by side in the Creative ZXr.
Initial Impression: I heard an obvious tone change around the mid frequencies and possibly a sharper roll off for the top-end (less sparkle). Needs way more testing before I can be sure of that.
Stay tuned for my reviews coming down the line. I have Burson Audio’s “RCA-to-RCA Cable+” up first and then I will dive into the head-to-head battle for top discrete op-amp!
