klipsch heresy 1 versus zu omen mk2

Haven’t heard either speaker but have heard the Heresy III and Zu Dirty Weekends and preferred the Heresy III’s. The DW’s are good speakers, especially for the price, and I’m not sure how close they are to the Omen but I’m thinking if you like the Heresy sound the III’s would be a nice upgrade from everything I’ve read about those who moved up.

I did hear both the III’s and DW’s with tube amps so not sure if that’s something you might consider down the line but Klipsch definitely respond to a good tube amp.

No experience with the Zu, but another upgrade option for your Heresy I speakers is to upgrade or replace the crossovers and tweeter with replacements from Bob Crites.  I did this to mine recently and am very happy with the results.  The parts in your crossovers are probably 30 or 40 years old.  Mine were all dried out.  The tweeters Bob offers have more extended range and add more detail without being "bright" or harsh.  Cheaper than buying new speakers, relatively easy to do, and a nice sonic improvement.

Have not heard Heresys (would like to) but I love my Omen DWs.  They are not the best speaker I have heard, but they are the most fun.  Big, dynamic, engaging sound.  I play mine with both tubes and solid state amps, so your Wyred amp should be fine.

Differences between Omen DW and regular Omen are minimal:
- Fancy backplate with ZuB3 cable hookup inputs
- Zu Mission cable harness instead of plain hookup wire inside
- ClarityCap filter capacitor instead of PulseX (which you can upgrade easily later or at order time for $100... I recommend this)

I can't answer your question of will this be an upgrade or not, but Zu gives you 60 days to compare them to your Klipsch, so you have nothing to lose.

Have heard great things about Zu but you already have some nice speakers.
I’ve done the Crites upgrades to KG2.5 (crossover kit and titanium tweeter) KG4 (crossover kit and titanium) , and Forte II (replacement crossover and titanium but later put the original diaphragms back). Crites is a pleasure to do business with and they make quality stuff. Highly recommended.
I’m looking for my next Craigslist vintage Klipsch to try it again.
