Some time has passed since Audio Note OTO SE Signature took over the amplification task in my audio system, and as it usually happens when a new component of higher quality has been introduced, some deficiencies intrinsic to other links in the audio chain are being revealed. Armed with some new knowledge, obtained during the communication with Peter Qvortrup, I went through a process of system optimization evolving around this single-ended amplifier with the main goal to bring the best out of it. I am glad that the end result is a level of enjoyment that surpassed anything I used to know.
