So on the recommendation of @Rikudou_Goku, I bought the $30 KZ DQ6 because I was disappointed with the way the Blessing 2 didn’t have enough “presence” for me.
The DQ6 stock are already shockingly good for the price. In particular the separation and imaging are really surprising, easily besting things that cost hundreds of dollars. Compared with the Blessing 2, the B2 has far more detail and speed, you can hear the texture of each note in a way you just can’t on the DQ6. But the DQ6 has none of the issues with “presence” I had with the B2, settling one question: I definitely prefer dynamic driver headphones. The DQ6 are just more fun to listen to, especially for rock music. They have impact and slam in spades. (Comparing these two, it’s also kind of funny that the silver color DQ6 I got looks exactly like a cheaper version of the Blessing 2; they both have a clear plastic housing so you can see the components underneath, but the B2 has a shiny metal front plate while the DQ6 has a silver colored plastic one.)
The main problem the stock DQ6 have is that they’re a bit shouty and harsh in the treble. I especially had a reaction on the song “Royals” by Lorde which has a snap sound all the way through which was much too present and harsh. So I tried the filter swap with the Tanchjim Tanyas recommended by @Rikudou_Goku. The new filter completely fixes the issues with the treble to a shocking extent, and makes these just sound good especially for the price. The only real issue is that, if anything, the filter tamps down the treble a little too much, making the it a little veiled. It’s not necessarily bad, if anything it reminds me a lot of my HD 6XX. (The HD 6XX sounds very different in other ways, or course, especially since the DQ6 is v-shaped while the HD 6XX is mid-focused.)
In fact, comparing the DQ6 to the Blessing 2 gives me flashbacks to my 6XX vs. Sundara comparison, but the differences here are even more extreme. Blessing 2 has better detail retrieval, speed, and clarity by far than the DQ6. It’s not even close. But I put a rock song on with the Blessing 2 and I think “that sounds really nice”, and I put the same song on with the DQ6 and I start bobbing my head and dancing around the room. It’s just a more pleasant experience. Obviously this isn’t a perfect comparison–the Blessing 2 isn’t the Sundara and the modded DQ6 isn’t the 6XX–I just find myself having a similar reaction to them.
The Blessing 2 also scales with my RebelAmp vs. the Qudelix 5k a whole lot more; you can really hear the improvement in quality on the desktop amp, while the difference is much less noticeable (but still there) doing the same comparison on the DQ6. In fact, the improvement of the Blessing2 on the RebelAmp is dramatic, where things that sounded merely good on the Qudelix taking off on the RebelAmp.
And so, ironically, the DQ6 made me rediscover my love of the Blessing 2 with the right music and amp. For example Hiromi’s “Silver Lining Suite” on the Blessing 2 with the RebelAmp just sounds astonishing, in a way that the DQ6 can’t touch. I had a similar experience with “Cables Rewired” by Bill Lawrance & the Untold Orchestra, which just sounds magnificent on the Blessing 2; classical music and film scores yielded similar results.
But for rock music and Jazz with a strong backbeat, the DQ6 wins for me over the Blessing 2, and it doubly wins when compared on the Qudelix. Also the DQ6 is just a better walking around on the street headphones, where ambient noise can cut out details anyway and the extra bass can help the music come through. They’re also much more forgiving of bad recordings than the Blessing 2 is.
I kind of can’t believe how cheap these are for the kind of performance you get. Separation, imaging, impact, slam, and fun. What a great set!
Based on how much I’m trusting RikudouDoku’s taste after my experience with the DQ6, I still kind of want to buy the FD5 in hopes that it’s like the 660S sweet spot was for my headphones (compared to the Sundara and the 6XX), giving me the detail of the Blessing 2 with the presence and impact of the DQ6. In any case, I’ll be keeping both the Blessing2 for the music it shines with and the DQ6 as a rockin’ beater.
Thanks again for the recommendation!
