Each little particular is decided and cured incredibly, even the only one headphone socket! The designer (Mr. Garlaschi) tested a lot of sockets (Neutrik and others), but that he adopted has the better performance, because even this little output has a resistance and this rhodium and palladium piece has perfect in our situation.
Yesterday I was thinking that (finally) I found what I was looking for. Until the first moment I had the R10 I have believed in incredible quality and I started the long history for a amp in the same class. Now the three piece of my eq (source-amp-cans) and cables… have as characteristic to let flow the music, as you said: the R10 “disappears”, the same is for the amp and even for the source and cables… conclusion: only music is the protagonist in this headphone system.
Best to all!
