I just got the 100 Delux mk2 a week ago still need more break in sound getting better after a week pass by,it similar to my Aleph 3 almost like my Almarrow 318B in midrange.
I don't have anything that I don't like accept a little hum at the speaker but you don't here in few feets away,over all good detail,midrange,air and bass and in my system with Hyperion938 the amp have to play at lease 10.30 O'clock to get good sound not like Almarrow only 9 what a powerful 18 watt class a tube amp.
Good Luck it a very good amp.
