Monoblocs to Stereo Amp

I am thinking about moving from Marantz Reference monoblocs to a high quality stereo amp due to the space constraints of my listening room. The Marantz's sound great with the rest of my system: Magico V3's, Esoteric C-03 preamp, Herron phono pre and Basis 2500/Vector 4 table--gives you an idea. Thinking of very high quality, newer but used Gamut 200i, Esoteric A-02 or Pass 350.5, or maybe the Evolution Krell 302e. The V3's like high current solid state amps. Am I making a mistake? Any advice as to the named units? Budget is up to $7000.
