Hey Werther,
That's a great question. Without copping out here's my answer. Either amp driven by the Micro-ZOTL on both speakers are superlative in their performance across the sonic spectrum ( Timbres/color, micro-details, sweet extended highs, 3D imaging, great sound-staging, and excellent bottom end performance).
The Triode Lab SET 2A3 is slightly more 'Colorful" with a smidge more of the "meat on the bones" imaging, the AricAudio SET KT-88 is faster, offers greater space around and between players, but overall is still as smooth as melting butter.
This would totally boil down to personal taste, not an objective measure.
