I absolutely don't agree regarding the Audionet Watt being close to the Humboldt.The Humboldt is in a complete different league, you get 90% of Stern-Heisenberg sound for a fraction of the cost with the Humboldt.The humboldt is uber transparent and ultra fast, you get a huge holographic soundstage, very solid bass and very smooth organic sound.It is not cold or analytical at all.IMO It is the world's best integrated up to msrp 50k period.Second place you have either the Vitus SIA-030 or the d'Agostino Momentum integrated.Third place you have CH Precision I1, Absolare integrated, and Aavik U-380.
Unless you have the budget for Stern-Heisenberg get the Humboldt.Watt and Max series is midfi compared to Stern-Heisenberg and Humboldt.Just my two cents.
