Questions to Klipsch Heresy IV owners

@deadhead1000
If you don’t have tone controls or an equalizer the best speaker choice seems to be high sensitive speakers.
My 89dB sensitive Tannoys are not sensitive enough. Not for low level listening and not for my 12 w tube amp.

@russ69
They are not sensitive enough for my 12 w tube amp. Unfortunately.

@czarivey
Many says that tube amps are the best choice for Heresy IV.

@simna I agree with you. Also you can try a Class A amp rather then tubes, a good substitution if the price of a higher watt tube amp is not practical. I’d still go for the tube and Heresy if it’s practical for you. Similar to you, I heard Harbeth and a good class A was magical, and it is for my listening habits. Hope the tube and Heresy do it for you. 

Hmm... not many Heresy IV owners in this forum.

Many horns tend to sound good at low levels. And break-in is subjective best to just use and hear improvements. I haven't owned the smaller models just the top 3 from Klipsch. But have heard many other models in a good num of systems.

Thanks for your opinions.
But I really need to know the differences between Heresy III and IV. Heresy III I thought was too shouty and harsh. At least with those amps and in those two rooms I've heard them.
