System Help

Looking for the best tube integrated amp under 2k for Sonus Faber Concertos and VPI Scout. Any suggestions would be appreciated
I'm using the Rogue Cronus - list $1895. Its 55 - 70 WPC (depending on tubes used) would drive the SF just fine. It has a built in phono amp that is adequate and a headphone jack for low impedence phones like Grados.
..just wondering why you specify a TUBE unit. Especially at that price point there are so many more solid state units that are worthy.
