If you feel that your speakers are neutral and that the amp also is classified or perceived as neutral, there might be a potential for trouble. Nevertheless, Neutral+Neutral does not have to equal ultra neutral or sterile. I have read a review of a pair of Avalon loudspeaker paired with Spectral gear, amp and preamp. By themselves, they all were described as neutral sonically, but when they were paired, they actually complemented each other's sonics very well. It was in Hi Fi magazine, a UK based periodical. But, if they get there and do sound a tad too cold or sterile, you can always add a tubed preamp and some copper IC would be able to tame the neutrality to make it livable. What sort of pre are you planning to use?
