Questions to Klipsch Heresy IV owners


I like to listen to music at low volume. But I think my current speakers sounds boring and lifeless when I turn the volume down. So I’m considering buying Klipsch Heresy IVs, but I have some questions.

Which speakers did you have before and how did the listening experience change?
Differences in soundstage? Not only width, but height and depth too.
What amplifier do you use?
Do they really need 500 hours of burn in to sound their best?

I’ve seen some calling Heresy IV a more “even” and “smooth” speaker” compared to Heresy III. And being a little less a “rock’n’roll” speaker, but instead a more “allround” speaker.
Can anyone confirm that?


Triangle loudspeakers in your price range play really well at low volumes, way better than my Heresy IIIs. Also, they are an easy load to drive, my 25-watt tube amp was perfect.

Class A SS amplification is the best for low volumes practically with any speaker even with lo efficiency.

my vote is for a high quality SET, autoformer passive pre, and single driver speakers ie Omega if your preference is lower volume listening 😃

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.

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

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.
