It is such a blessing to be here on Head-Fi to briefly share my thoughts on the QP2R, especially when comparing it to the QP1R, and sharing my opinion(s) if I believe the QP2R is worth it over the QP1R.
Disclaimer: I received the QP2R for free for exchange of my thoughts about the product.
The QP2R utilizes one Micro SD card slot so the player can accommodate the Balanced connection. Purchasing as large of storage capacity card as possible shouldn't be too big of a sacrifice of the second Micro SD card slot the QP1R utilizes. Also, the internal memory of the QP2R is 64GB as opposed to the QP1R's 32GB.
The QP2R charges via USB-C, which means very fast charging (charges in at least half the time it would take to fully charge the QP1R via Micro USB).
Adding and deleting tracks to the QP2R are the same as the QP1R (just like a USB thumb/hard/SSD drive).
Navigation is a bit easier with the QP2R, and I personally keep my player on High Bias and High Gain for best results. I usually don't listen to very sensitive IEMs with the QP2R such as the Andromeda (even though it sounds heavenly when it's Balanced) - however, most headphones are powered with plenty of aplomb, especially Balanced. More about power and power comparison(s) later.
Make sure to take care of the Questyle players, keeping them in the 1st party or 3rd party cases, and try your best to never drop them.
The build of the QP2R is similar to the QP1R, with an extra Balanced port, one less Micro SD port, and a USB-C port replacing the QP1R's Micro USB port. The wheel and buttons of the QP2R are very similar to the wheel and buttons of the QP1R. The Gorilla Glass of both the QP1R and QP2R are quite the looker.
I'm currently using a QP2R Dignis black leather case that came from Final Audio - make sure to inquire with either Dignis and/or Final Audio to obtain that particular case.
With regard to UI Navigation, the QP1R shows:
Play by Category > Songs, Album, Artist, Genre, Playlists
The QP2R shows:
Category > Track, Artist, Album, Genre, DSD
Playlists > Favorites
Browse Files > Internal memory, TF card
QP2R navigation: Going into "Genre" will take you to a song/track list, just like the QP1R.
The sound of the QP2R is very good, better than most DAPs, aside from the QP1R - in SE mode.
I paired the QP2R with a couple of the latest headphones in my stable: the Massdrop X HIFIMAN HE-35X and the Massdrop x Beyerdynamic DT 177X GO.
Here's my brief thoughts of the Massdrop X HIFIMAN HE-35X:
Massdrop is rolling out a new pricing structure. Paraphrasing from Mr. Fernandez: "We are doing this to reward members that support products early by giving them a price break before a product goes into store.
For the HE-35X the product is available at a special launch price until April 18 or until the first 750 are sold.
We want folks to know about this new pricing plan which will apply to future Massdrop Made headphones."
Here is the link that talks a bit more about the pricing:
With regards to my thoughts about the HE-35X, it is everything you would want, and then some.
Compared to the original HE350, the HE-35X has more palpable bass, at around +5db to my ears. The upper bass and subbass is a bit more visceral than the HE350 with modifications such as the paper towel mod and Brainwavz Angled Pads (BAP). Smoother rumbling than the mods, with comforting touches to your head as the tracks play on.
The HE-35X has a toned down midrange compared to the HE-350, and is buttery smooth.
In the HE350 review, I stated "treble may sound bright to very bright"; the HE-35X has treble that is smoothed and as a result, a joy to listen.
Soundstage isn't as expansive as the HE350, but having a bit more lower register, with a smoother midrange and treble is a good compromise to embody, in my opinion.
With regards to headphone comfort, the HE-35X feels as good on the head as the HE350 with modifications.
The total presentation is that of an upgrade of the original HE350, the result of the reviews and owners' feedback.
The HE-35X is a audiophile value if you choose to purchase the headphone.
One of my current favorite pairings is the Questyle Audio QP2R with the MASSDROP X BEYERDYNAMIC DT 177X GO (I'll call it the DT 177X GO from now on). You are able to listen to the headphone Balanced, but I didn't try it out yet - hopefully I can borrow a mini 4-pin XLR Balanced cable to try it out with the QP2R in the near future. My thoughts are about SE, not Balanced (to think the audio may sound more amazing Balanced!) The sound of the DT 177X GO is what I would like to call musically neutral. The entire spectrum is very clear and holographic. Not a lower midrange and bass/subbass presentation such as the TH-X00 series, but a champion when it comes to immense clarity and neutrality. The comfort of the headphone is very comfortable as well - the velour pads are soft to the touch and feel like an ear massage acoustically and physically. This is a headphone that can easily be used for mastering, or listened to while relaxing with your favorite beverage of choice.
My sister's husband Christian (XAVR), who is a singer/songwriter, and uses mastering headphones offers these thoughts:
"Sounds very good. Has a flat sound, and gets really loud. I really like the shell - it seems like it makes the audio sound better. I like the velour pads more because they attribute to a warmer sound."
This collaboration headphone marks a point where a neutral-based headphone can sound amazing to the ears and feel great as well. For those that have tried it to really enjoy the collaborative headphone is awesome, in my opinion.
Here's my thoughts about the DT 177X GO:
The bass is not overbearing in the least, and is nice and controlled. No huge spikes or dips in the subbass and midbass areas to my ears, but just enough for you to be adequately satisfied.
The midrange is clean, almost sterile, yet musical in its own right.
The treble is methodic, and not sibilant. The upper midrange into the treble may be the star(s) of the show, where you may not be searching for a thumping subwoofer feeling, but yearning for a sweet, clinical mid to upper register. The DT 177X GO delivers this and a whole lot more, in my opinion.
The soundstage and detail are very good, especially emitting through a closed back headphone.
The DT 177X GO is an excellent buy if you are searching for a true content headphone.
Where the QP2R really shines is Balanced. You've got more power, overall clarity, separation, and detail when it comes to Balanced of the QP2R compared to the SE of the QP1R and QP2R. If you are seeking overall sound quality, go for the QP2R Balanced, but if you want a bit better sound quality SE, go for the QP1R.
Which brings me to the main question: Is the QP2R worth it over the QP1R? I would unequivocally say yes. Main reasons:
The QP2R overall sounds better than the QP1R. The QP1R is currently going for $749 while the QP2R is currently $999. The around $150 price difference is worth it for the increase of overall power, better UI navigation and better sound quality in comparison to the QP1R. You can purchase both from T.H.E. Source AV, or Moon Audio.
