ตัวหูฬังสวยกว่าเดิมมาก เสียงดีกว่า
เสียงดีจนมีคนบอกว่าใกล้เคียงกับ LFF Paradox, LCD3
บางคนถึงขนาดบอกว่าชอบมากกว่า JPS Abyss ซึ่งราคาต่างกันประมาณ
สิบเท่า (5000+$ vs 600*)

The first area I felt was improved was the comfort. Even though the AD is slightly heavier, they actually felt lighter on the head. I believe Dan said the added comfort is a result of the sleeker more optimized cups and the new ring mechanism that he developed for the Alpha pads. He showed me the ring that the Alpha pads slip around and it truly makes for an easy way to swap pads if the user so chooses. I've had my share of problems with swapping pads in the past and this is by far the easiest it has been. Kudos to Dan for creating a mechanism that makes swapping pads easy. I'm sure many modders, etc. will be happy for the improvement. Another improvement I experienced immediately was the new cable connectors. My pair of MD 3.2 is still the standard configuration that requires the right-angle connector, and for those owners that like to upgrade to aftermarket cables, it was somewhat of a pain. Although I'm not completely enthusiastic about the angle of the connectors (similar angle to the Audeze offerings), but I do like how they are now easily swappable and popular enough configuration to have no problem finding a suitable replacement.



So how did they sound? Well, I may not be experienced as some of the beta testers, but I do know what I like and have a firm grasp of what I don't like. I can safely say that I came out of the listening session with a new feeling about closed, full isolating headphones. The AD not only isolated just as well as the MD, but after hearing it I'm still amazed at how open these closed headphones sound. They retain all that is good about the MD, and improve on those things that were somewhat lacking. I'm talking about the slight congested sound, smallish soundstage (in comparison to all headphones), and the of course the lack of air. The AD almost sounds like a completely different headphone, and dare I say closer to the technical prowess of the HD800 than remaining the same MD. Not to put down the MD, but it was clearly not as technically proficient as any of TOTL offerings.



What really boggled my mind was how open and airy these closed headphones sounded. The soundstage is wider, and a tad deeper, and the imaging is more accurate. Instruments, especially piano and violin were very impressive. The natural timbre of this headphone is only bested by a select few that are x2, x3, even x4 times the cost. Vocals were also very natural and realistic, and never sounded harsh. The neutral-like sound signature of the AD helps with more complex music and definitely is a step up from the MD for those that listen to classical, orchestra, etc. -esque genres. As some of the testers have said already, these headphones are incredibly fast. This area in the headphone market is very sparse and not very many headphones have me grooving and air drumming to the beat, but these had me going wild. I've heard a few of the Audio-Technica ADXXXX variants and these remind me of the speed of those headphones.



The general sound signature of this headphone is quite neutral. This is something that can be loved or hated. Some people may find the AD to be too "bland" for their tastes; others will be jumping for joy for something that is truly reference. Reference, in my mind, is something that can be used in a recording studio to mix/master music. It is a sound that has no emphasis anywhere in the spectrum and lays out the layers of music very well. While not being quite (and I do mean quite) there at the HD800 level, at half the price, Dan has something seriously game changing here. The AD is a woman you can marry and have a nice life with (kids... white picket fence... whole nine). I truly believe Dan has something special here that will really turn heads. I hope the fat cats out there in the headphone industry are reading this thread because they should be pissing their pants. This should scare them, because I think this headphone will become The Reference for many, especially those that are on a budget. I want to thank Dan again for the listen and I hope him the best with this venture and future ones.



I encourage everyone that has heard the MD and is looking for that extra push to go out and try these. If you can’t, take the plunge, they are definitely worth their asking price and then some.

dBel84 ก็ให้คำวิจารณ์โดยละเอียดไว้ดีมากเช่นเดียวกัน ตัวที่เขาฬังเป็น prototype แต่เขาก็คิดว่าคงไม่ต้องเปลี่ยนแปลงอะไร
Appearance:

Shape of new cups is very slick - they had not yet been painted .

Connectors are much sturdier feeling than than mini xlr

Pads - they are very snug, i personally prefer more space but i understand they play an important role in the sound presentation and have been custom made to achieve the isolation they offer.



Comfort:

actually very comfortable , weight well distributed, Tight clamping force but not uncomfortable even after quite a session this evening. Internal pad volume is small , this probably contributes to a narrower soundstage/soundfield.

leather headband really makes a difference, no ache on the top of the head as with stock T50rp



Sound:

Initial listen - just flicking through several favourites = very pleasant , nothing stood out as offensive, good detail and the most balanced bass I have heard on the MDs.



More critical listening:

Again very pleasant to listen to. The following is real nitpicking for your feedback Dan - take it with a pinch of salt.



Bass. Good weight and sense of layering, never overwhelming and I feel this has better balance than the MDs you had at ChiUniFi. Some of the subtle upper bass / lower mid layering is lost - probably due to a slight bump in mid presentation. Never congested, but not as detailed/layered as I am accustomed to hearing.



Mids: I feel the mids are a little forward with a very slight upper mid etch. Really nothing to write home about and it gives a sharp horn blow a bit of bite. Unfortunately some piano keys are also a little on the sharp side but never wincingly so. Just settling into the music , the overall impression is a fairly even frequency response. It is just when you choose music to emphasize certain traits that it sticks out. My impression is that there is a wide , inoffensive hump at about 3K. No ringing and non of the funky mid troubles that the stock T50rp have.



Highs: great detail and separation, not as much air but very focused.



soundstage: very good and realistic but not as wide as either of the other T50rps I have. I suspected this while listening, it never sounded narrow or cramped, but it did not sound as wide as the paradox or RDs modded T50, so I pulled them out when I was done just to confirm my impression.



just to finish up , i ran the stereophile test disc and noted the following

- there appears to be a 125Hz resonance with pure tone : I do not hear any evidence with music

- frequency sweep , remarkably smooth . I do hear a little more prominence 2K-4K and again at 8K ( the slight mid prominence I heard with music but I didn't hear any offensive representation at that higher 8K point. )





My take : a job well done. I don't think I would really want to change anything with the way these headphones are voiced. I think they will appeal to a wide audience and offer remarkable performance for a closed headphone.





bear in mind that these were preproduction impressions and Dan was still tweaking things , I did not play with the bass adjustment which was not the same screw mechanism as in the final version.

มีขายแน่ๆๆครับ เดี๋ยวผมเช็คข่าวคราวให้ทุกๆๆท่านอีกทีนะครับ 555

ทำราคาไม่เกินเมืองนอกนี่ตัดสินใจไม่ถูกเลยนะครับ 901 หรือ ตัวนี้ก่อนดี....

จะถามเรื่อง adapter ด้วยครับคือถ้าไม่ใช่ 4 pin xlr แต่อยากเอามาใช้กับ 901 นี่จะมีทางไหมครับ. หรือแปลงจาก xlr to trrs , xlr to single end, trrs to single end

ขอข้อมูลขั้วสายด้วยนะครับว่าเป็นแบบไหน ใช่แบบ HE500 หรือไม่ครับ

คิดการใหญ่แล้วครับ ขอข้อมูลนิดนะครับ อยากลองวางแผนดูก่อนครับว่าจะจัดชิ้นไหนก่อน



ขอบคุณครับ

นอกจากคุณภาพเสียงที่ดีมาก ที่มีคนบอกว่าใกล้เคียงกับเสียงของ Sennheiser HD800 ซึ่งแพงกว่ามากกว่าหนึ่งเท่าแล้วยังมีความสวยงามเช่นเดียวกับ Fostex TH900 ซึ่งราคายิ่งแพงขึ้นไปอีก

อ้าว!!!ยังไม่เปิดรับจองเลย

ได้ข่าวว่าสามารถเทรดกับ Mr Speakers Mad Dog ได้ด้วยโดยเสียเงินเพิ่มไม่มาก

และสามารถเลือกสีได้ด้วย (อันนี้ยังไม่ยืนยันจากบริษัท) ถ้าอย่างนั้นจะน่าสนใจมาก
และคนที่เพิ่งซื้อ Mad Dog ก็ยังไม่ต้องประกาศขาย ยกเว้นแต่ว่าได้ราคาดีกวา

พี่ตอยจัดไปคิว 0 เลยครับ

Purrin (Marv) ได้ให้ความเห็นเกี่ยวกับ Alpha Dog ไว้ว่าแตกต่างจาก Mad Dog
และใกล้เคียงกับ Fostex TH600 หรือ Fostex TH900 ซึ่งตัวหลังราคาแพงกว่าสามสี่เท่า
และมี screw สามารถปรับระดับเบสได้ให้ได้ใกล้เคียงกับ TH600, TH900 (บางคนว่า TH900 เสียงเบสมากไป) โดยไม่ต้องใช้ EQ ช่วย เขาบอกว่าลักษณะเสียงเป็นแบบอ้างอิง เป็นกลาง รายละเอียดดีและตอบสนองฉับไว

While the MD can be described as with a touch mid-bassy or dark tilt. The AD are not that all all. You will be best served by the TH600 or TH900 depending upon your budget. As Dan even says on his website: "Reference sound quality; neutral, detailed and fast"


It may be possible with the screw adjustment, you can get a mega-bass version. An alternative is to use EQ and boost up the bass 5-10db. That should get you TH600 or TH900 bass. However the quality of the bass, especially the low bass may not be that great. The T50RP driver is small, and as a planar, does not have much xmax (diaphragm movement) compared to the larger area traditional cone / voice-coil and increased xmax of the T600/900 driver, which would lend itself to cleaner loud bass.

ถ้าลักษณะเสียงแตกต่างจาก Mad Dog หรือ modded T50p ตัวอื่น ๆ เช่น Smeggy Thunderpants, ZMF modification, Paradox version (LFF) ก็น่าสนใจมาก คิดว่าเสียงคงใกล้เคียงหรือดีกว่า Paradox แต่ราคาถูกกว่าและสวยงามกว่าเพราะมี
3D printing ตามรูปข้างบน

รีวิวครับ น่าสนใจมากๆ

Sound quality:



Haha, here's the juicy part. I did write that these sounded "unbelievable", right? I meant that in a good way.



Test setup is as pictured. Burson Conductor or Schiit Lyr and Bifrost were the primary sources here. Dan wasn't cheating with $2000+ amplifiers. You can get amazingly good sound out of the Alpha Dogs with a <$1000 setup.



But if I just did a plain listening test, then it wouldn't be cool. So Wolfetan44 helped me out. He and I brought our own headphones over for a bit of fun. Paradox T50RP and Audio Technica ATH-W1000X.



Please note that the ATH-W1000X is very close to my personal reference sound signature because I modded it, and I'm very familiar with it, so it'd be an unfair comparison for the Alpha Dogs just on that point alone.



How did the Alpha Dogs fare against those 2 headphones?



Pink Floyd's Money - Dark Side Of the Moon (HD quality): this was one of the tracks that Dan had on his computer. I have heard this song probably no less than 100 times. And I have heard it out of a lot of headphones. Up to and including the SR-009 and Abyss.



Paradox T50RP: a bit narrow and claustrophobic to my ears, but good clarity, good details, and very good depth and layering ability. Despite having smaller soundstage than the other 2 headphones, this one held its own.



ATH-W1000X (modded): expansive and very good soundstaging, very good depth, layering, details. Like I said, it's very close to my reference sound signature, so almost nothing is lacking to my ears. If upper midrange was a bit more subdued, it'd be perfect.



Alpha Dogs: surprisingly, soundstage is almost as big as the W1000X. Details are a bit more subdued than the other 2 headphones to my ears, but smoother than Paradox. If my W1000X was at stock, I'm sure the Alpha Dogs would decimate them. As is, I think the Alpha Dogs is a better value than the W1000X just because you don't have to fiddle with mods and so on to get them to sound right.



Eric Clapton's Lonely Stranger - Unplugged: this was my own music. I couldn't find this track on Dan's computer, but he allowed me to load my own music. So I went to town with the "authority" that was just granted to me. (sorry, Dan! I couldn't resist it!)



Paradox T50RP: being that this is a live recording, the Paradox did a good job with instrument separation and layering. Details were simply amazing. However, there was still that claustrophobic feel. Midrange was fairly good, but not as liquid as the other 2 headphones.



ATH-W1000X (modded): huge soundstage. It sounded like I was sitting there on the stage. Midrange was a tad more forward than the other 2 headphones, so it was quite weird... given that the soundstage was so huge. Otherwise, very good details, very good midrange presentation, and overall very pleasing.



Alpha Dogs: soundstage a bit lacking compared to W1000X. But. But. BUT. Okay... BUT the overall presentation was more pleasing and natural than the W1000X. Why? Because of that midrange emphasis on the W1000X. ADs don't have that midrange emphasis, so they sounded more natural. The presentation is obviously more colored with the W1000X. ADs presented a far more natural and linear presentation. Even though I said that the W1000X was closer to my reference sound signature, I was leaning toward Alpha Dogs with this song. That's a huge feat for the Alpha Dogs.



E.S. Posthumus' Ebla - Unearthed: this was also my own music. This track was solely there to test imaging and soundstage performance.



Paradox T50RP: again that claustrophobic feel. I think soundstage is inherently a weakness with this headphone. Though the layering ability was just amazing. I also loved how details were rendered.



ATH-W1000X (modded): crazy expansive soundstage. Unnaturally big. I'd only heard bigger soundstage from 2 headphones... the ATH-AD2000X and Sennheiser HD800. Due to the midrange emphasis, imaging was spot on, and I could almost pick out individual voices in the choir. This was probably an unfair fight for the other 2 headphones, or so I thought until I heard the Alpha Dogs.



Alpha Dogs: very good expansive soundstage. Not as big as the W1000X, but again, more coherent. There wasn't that much of a midrange emphasis, so vocals took a backseat, but it made the soundstage more natural. I didn't expect to, but I think I enjoyed the Alpha Dogs a lot with this song. Best of all, I remembered there was a cavernous feel to the soundstage when I was listening to this track with the Mad Dogs. There was no cavern with the Alpha Dogs. They sounded truly like "soundstage" of an open-backed pair of cans.



E.S. Posthumus' Nara - Unearthed: the next track in the same album. I often used this track to test bass performance.



Paradox T50RP: soundstage notwithstanding (I don't think I need to keep whining anymore), bass was pretty well-rendered. I could use a little bit more of it, but it sounded pretty good to my ears with this headphone. And it never bled into the midrange. However, due to the soundstage, bass felt a little more... one-directional. Like it came from just one source instead of multiple.



ATH-W1000X (modded): directional information is recreated very well. I could clearly hear where bass is coming from, and whether it was from a small or big drum. However, it felt like sub bass rumble could be a little bit more pronounced.



Alpha Dogs: surprisingly, again, these came out on top in a track that I didn't expect them to. Impact was lacking compared to the W1000X, but bass sounded very linear. Sub bass rumble was well on par with the rest of the frequency response, and soundstage was just lacking a tiny bit behind the W1000X. Needless to say, that means they were better to me than the Paradox.



Overall, I'd say the Alpha Dogs was the most well-rounded of the three headphones mentioned, despite the fact that I own and really like one of the two that I compared the Alpha Dogs to.



If I have to pick a headphone out of the three, the Alpha Dogs would be the obvious decision. It was more comfortable than the other 2 headphones, it isolated far better than my W1000X (the W1000X is actually semi-open rather than fully closed like the Alpha Dogs), and I wouldn't have to apply any further modification for them to sound great.



And yeah, that was how the Alpha Dogs sounded unbelievable to my ears. I came into the review expecting them not to be able to measure up to my W1000X, which... if I have to add, I do prefer over the HD800, LCD-2, HE-500, and TH900. No joke. All 4 of those headphones were available at the meet for me to demo and compare, so it wasn't like I just pulled that out of nowhere.



I think the Alpha Dogs are clearly the best closed headphone under $1000. Bar none. And that's because the TH900 exists. And technically, I think the TH900 does have slightly better imaging compared to the Alpha Dogs. Just like how my W1000X can still beat out Alpha Dogs at certain things.



But... this is a big but... the Alpha Dogs is priced at $599. The TH900 new is $1499 even after the recent price drop. You're paying more than twice the price tag for something like a 5% improvement.



My modded W1000X is probably a better competition at around $499, but... I put in multiple hours tuning the sound, the ear pads were swapped (the L3000 ear pads are like $100 a pair!), and I had to put in a lot of things afterward (felt, dynamat extreme, etc...). The actual value of that W1000X is close to $800 - $900 not even considering the hours I spent trying out different things that didn't work, and I don't think I can replicate a second pair that's even close to that. And even after all that, it's still not as comfortable as the Alpha Dogs, nor does it isolate as well as the Alpha Dogs.



Additional note: after hearing the closed-back Audeze prototype, I still maintain the above sentiment... that the Alpha Dogs are the best closed headphone under $1000. But that's not because I know anything else about the prototype (other than how it sounds like), but because I think the Alpha Dogs still offers something unique for the money
