biamping Dunlavy v's-thoughts on tubes

have settled in on my sim audio w-10 monos(love them)- was thinking of horizontil bi- amping to bring some warmth to the tweeters- maybe using a tube to run the upper end- Do i neeed a external crossover or can this be done simply with the Duns- thanks,gary
you should be able to get away with the dunavies only since they already have internal provisions to split the signal on the two biwire posts. That said if you cross over out of the preamp and remove the bass signal pre power amp you should have more headroom on that amp since the low end, power demanding portion of the signal won't even hit the amp...that's the way i'd set up a pro audi system anyway
Almost forgot...tubes work killer with the dunlavys. i use vtl 185s
