I love the Ethos. It's a very balanced cartridge and that's a really good thing. The sound never gets old. I also find I just like listening to it.
It's bigger and bolder sounding than my ART9 and Kiseki Purpleheart. The ART9 is a bit more polite and the Purpleheart is rounded and warm and just a bit backward leaning in its presentation. The ART9 is more conservative but equally as good. The Purpleheart is sweeter than them both--but I haven't played the ART9 right before or after the Purpleheart in awhile.
It is not aggressive or harsh. BUT its presentation is big, bold, clear and somewhat powerful. The loud end is robust and not bloated. I recommend it without reservation. It is well worth the price.
I'll say this-- I feel like I'm missing nothing but magnifying glass detail around things. The Ethos doesn't miss the detail, but rather it doesn't highlight as much as the ART9.
It's amazing you get this much good sound for the price.
PS My system has some warm components but my main speakers are horn loaded. I also like it with a set of ribbon tweeters.
