I found a single thread on computer audiophile from elberoth, I guess that is the one you were talking about, he says that he prefers the AP over all others he's tested, including the Offramp. Most people disagree with this though. Anyone else?
Audiophilleo vs Empirical audio offramp
I currently have a metrum octave DAC being fed by an Audiophilleo 2 converter. I've been thinking of replacing it with an Offramp 4 or 5, but am not sure if it is worth it. Has anyone compared these two directly (doesn't necessarily have to be with a metrum DAC)? Most say that the offramp is slightly better, but does this increase in performance make it worth 3x the price (since you will also need to buy a SPDIF cable for the offramp). Let me know what you think.
