Knghifi,
Unfortunately, I had to sell the Gamut to get the funds to purchase the Rowland - and therefore never heard a direct comparison. And, since the Andras are "warmer" than the Eidolons which are driven by my Spectral gear, I really can't paint an accurate picture of the difference there either. Perhaps I should switch the amps around in my two systems. It would be easy to put the Rowland into the Eidolon system but more difficult to put the Spectral into the Eggleston because I would have to switch interconnects and speaker cables - due to the Spectral requirement for MIT only.
Based on what I know to be true about the Rowland vs the Gamut, I would expect your assumption about the Rowland being a little warmer to be valid, but having never heard a same-time direct comparison I can't really say definitively.
I do think that the Rowland does a better job than the Gamut on powering the Andras to their full potential on orchestral crescendos etc. because of its huge power reserve. Detailing, resolution, soundstaging, are all exemplary.
I am quite pleased with the Rowland.
