i own 1.6s . i am using a vtl deluxe 120. i probably don't listen as loud as you do. i average 70 to 80 db. i have no problem using the triode mode--about 45 watts.
if you want to listen at spls approaching 90 db, consider that at times you will be listening at levels which exceed 90 db. you might consider a more powerful amp.
i know, a lot of owners believe a high wattage ss amp is appropriate. i have heard them driven by a 500 watt ice power amp , as well as a 300 class a amp. since dynamics are unimportant to me, while timbre is most salient, i appreciated the ss amps at frequencies of 150 hz or less but did not like what i heard at frequencies exceeding 1000 hz.
