First, a big thank you to Andrew for his patience and advices. I already own the QDC Anole VX and was looking for something new. As my budget was limited to a certain sum I finally decided to go for the Mezzo LE. Already on first audition I was blown away by the resolution, Instrument separation and huuuuge soundstage. The DD bass is phenomenal and listening with Mezzo is like being live in the studio/stage. Everything was a step better with the Athena cable. Up to now I did not try to use the tuning control. I am enjoing a lot the Mezzo, highly recommend.
