I just rebuilt recently my loudspeakers Xover with top Cardas Litz wire,WBT connectors, and $1500 in Xover parts , no factory even at $30 k are as good , my point mfg take many shortcuts, Magico A5, Marten ,using mid grade Mundorf Parts when Mundorfs top capacitors are their Supreme line Not Evo , the A5 is the first to use their Excellent New Ultra $$ resistors which is a good start But on a $25 k speaker you deserve much more , in our group our Magico friend is upgrading his capacitirs now . My ears are not just getting used to the new parts
there is is vast improvement in imaging,soundstaging and detail
another guy has the exact Dynaudio 3.4LE speakers
and now he is saving for the same mods it was a profound improvement ,
used$3k now better then many in some respects then the majority of $10-12 k speakers . buying a Quality used component gives you great value and ability to truly raise the Audio bar !!
