*Warning
After rereading this, I feel like I got off-topic and just really reviewed my headphone collection. I don’t know how to really give an impression on an amp. I wrote a lot, so I don’t want to just delete this… If you want to read it, appreciate it, if not, understandable. I just wrote what I feel like the Allnic HPA-5000XL offer to my setup. I got about 123.5 hours into the Allnic HPA-5000XL amp in this post. You need about 300 hours to fully burn in the all-nickel core transformer, or so I heard…
Current Setup: Roon > Pi2AES Black Plexi (Ropieee) > [Wireworld Chroma 5 Digital Audio Coaxial Cable] Mojo Audio Mystique EVO Basic > [Audience Ohno XLR] Allnic HPA-5000XL > Onkyo A800
I tried RCA with the Allnic, but I feel like the Allnic sounded boring without XLR interconnect. The XLR interconnect provided a lot more juice and songs felt more exciting to me. I also tried to use only 6.3mm and no XLR since my other amps only use 6.3mm jacks. I also feel like SE output and balance output are the same. Input-wise, I would recommend going with balance cables.
Impression Post
All right, I said I was going to listen to my La Figaro 332C and then listen to the Allnic HPA-5000XL. The whole point was to remember the “tube sound” and wanted a bad example (La Figaro 332C) vs a good example Allnic HPA-5000XL. I also listen to my B22 amp to gather more characteristics from other amps as a reference. Before I have gotten to the 100-hour mark on the Allnic HPA-5000XL, out of the box the Allnic HPA-5000XL had great clarity. Besides that, don’t remember anything else being impressive. As the amp continues to get more hours in, the sound from the Allnic amp slowly becomes more and more impressive. I think the soundstage really opens up after the 100-hour mark and clarity also got a level, but not too dramatic compared to hour 1.
My brain started to think more of the Allnic products thanks to the Allnic interview video hifiDJ posted earlier in the thread. In the Allnic interview video, the founder/engineer Kang Su Park described the Allnic tube amps to be very special compared to the current day tube amps. 1 thing that makes Allnic Tube amps more special compared to their competitors is that most of the parts are made in-house, including the all-nickel core transformer and their signature attenuator. The reason for making in-house parts is that Kang Su Park wasn’t really satisfied with the parts offered in the market to him, so he just made his own parts. The whole goal for the Allnic amps is to have minimal distortion, musicality, and speed. Why didn’t Kang Su Park just create a solid-state amp instead of all these tube amps? Not too sure, but I think it’s probably why many of us own tube amps. Because that “tube distortion” just sounds so good. In my opinion, tube distortion help gives the body and texture to the music, and that helps the music sound more realistic to me instead of sounding thin like talking to someone over the phone vs real life. For tube amps, Kang Su Park like to use the OTL/OCL design. He stated in the video that both the OTL/OCL design is the best design for tube amps to let you hear the tubes without the unwanted distortion and unwanted artifacts. So in other words, he wanted to provide the purest form of music to everyone in the world. In order to do that, you will most likely have a vinyl setup using an all-Allnic setup.
I think with the Allnic HPA-5000XL amp, Kang Su Park successfully succeeded in a pure form of audio in a shape of a headphone amp. Listening to my La Figaro 332C on low volume, the resolution was pretty good for the $100 tube amp, but it was probably because I am using the Mystique Evo (basic) DAC. When I turn the volume higher on the La Figaro 332C, I notice a drop in resolution and the audio sounded more distorted to me. Switching over to the Allnic HPA-5000XL, the resolution was a lot better, as it should be, and consistent. As I slowly turn the volume up on the Allnic HPA-5000XL, the resolution still remains crystal clear. No hum, no hiss, solid black background on the Allnic HPA-5000XL. When I first got the Allnic HPA-5000XL, I heard some noise, but later found out it was my computer noise. Switching to a dedicated streamer, I can truly appreciate a true black background from the Allnic HPA-5000XL even when using the most sensitive headphone like the Onkyo A800 (32 ohms).
Comparing the soundstage with the Allnic HPA-5000XL with the B22 and La Figaro 332C, I feel like the Allnic HPA-5000XL help push for a more 3D type of soundstage like the music is being played around me rather than in front of me. I especially felt that with the ATH-L3000 headphone and even on the D8K Pro LE on certain tracks like Sing This All Together (See What Happens) by The Rolling Stones.
Bass on the Allnic HPA-5000XL is clean. That’s a keyword for pretty much all the sounds coming out of the Allnic HPA-5000XL, clean. For bass, I really like the Onkyo A800 > ATH L3000 > D8K Pro LE. I mostly use the Onkyo A800 for the bass test since its pretty good for sub bass and bass. The Onkyo also has that visceral sub-bass effect as well. I used the song Dove by Cymande and I was just jamming the whole time. Let me quote a fellow Redditor on how clean a bass guitar should be, “No rattle, no fret buzz, no compression twang, no distortion, no extra notes ringing, no amp hiss, and no hum.” That was really clean and I am not sure if any other amp could get cleaner than the Allnic HPA-5000XL at least under the 10K mark. For Rap songs with clean bass, I use Break the Bank by Schoolboy Q. As expected, the bass in that song was clean, not muddy at all, just very clean as it should be. Subbass rumble was tamer in the Allnic HPA-5000XL and didn’t really overpower the music. The Allnic HPA-5000XL had a nice balance of sub-bass rumble while making sure the songs since had a nice amount of clarity. I use the song Brambleton by Pusha T. Subbass had more rumble in the B22 amp, but it muddy up and can overpower the rest of the songs. That is why I found the Allnic HPA-5000XL perfect for my favorite headphone Onyko A800. The Onkyo A800 actually has a good level of clarity. The Onyko A800 clarity will get overpowered if you cannot tame the bass. The Allnic HPA-5000XL does exactly that with added benefits. I’m glad I actually chose right on the first high-level tube on taming the Onkyo A800, only had to spend a big 1 time on my perfect amp for my Onkyo A800.
Mids on the Allnic HPA-5000XL just sound so sweet to my ears. For Mids, I had to go with my Sennheiser HD580 Jubilee. At this point in the stage, I am pretty tired lol. I listen to the 2 Cellos, “Let There Be Cello” album. Cover songs were Hallelujah, Perfect, Vivaldi Storm, and Whole Lotta Love/Symphony 5. I feel like the Allnic HPA-5000XL helped push the Sennheiser HD580 Jubilee on how a Cello should sound, sweet, rich, and exciting. I had to do at least 1 female vocal, so I chose Stellar Stellar - From THE FIRST TAKE, Hoshimachi Suisei. Oh my lord… geez, this is where the tube sounds really help in my opinion. I feel like tube sounds really help recreate vocals in becoming more “real” and it really feels like Suisei is really singing in my ears. Her vocals sound organic like her vocals had more body, weight, and soul compared to all the other amps I heard with the Sennheiser HD580 Jubilee. Hearing her pause to catch her breath, the Sssss not hissing on me, the minimum distortion Allnic HPA-5000XL was truly magical on her vocals.
Treble on the Allnic HPA-5000XL. I forgot that song my co-worker introduce me to. It was a jazz song with high hats with a “delicate” touch. I remember sharing some DAC and he didn’t like it because the high hats sounded more aggressive vs what the artist was known for, a delicate high hat touch (If you know what I am talking about, a reminder of the artist’s name and song would be great). Whatever, I’m using the D8K Pro LE to test out treble and the song Wicked World by Black Sabbath. High hats . It didn’t offend me, it didn’t screech my ears, and had a nice decay.
I didn’t mean to write all this . I think I ended up just reviewing my headphones lol. I don’t really know the best way to give impressions of an amp other than it drives my headphones well. I feel like the Allnic HPA-5000XL drove the dynamics headphones to their max potential. I heard a few people, like maybe 2 or 3 say that the Allnic HPA-5000XL is really meant to drive headphones in the impedance 30 - 50 and some planar headphones to their max potential. I feel like that is true as I don’t think I ever heard any amp drove my Onkyo A800 (32 ohms), ATH-L3000 (45 ohms), and others to this level before. I am not confident in saying the Allnic drove the D8K Pro LE to its max potential because I think the Onkyo A800 and ATH-L3000 sounded more amazing when I was driving the Allnic HPA-5000XL. I even liked the Sennheiser HD580 Jubilee more compared to other D8K Pro LE to be honest when I was driving it with the Allnic HPA-5000XL. Hearing the D8K Pro highly rated by many people, I’m sure I am probably missing something to drive the D8K Pro LE to the max potential. But I might be just extremely biased towards my dynamics headphones lol. I think the Allnic could bring out high impedance headphones potential at a high enough level. Probably not the best, but I really like how the Sennheiser HD580 Jubilee sounds when using the Allnic HPA-5000XL. Overall, the Allnic HPA-5000XL is definitely probably the best amp to drive your low-impedance dynamic headphones to their max potential with its pure audio and low-distortion design. You have to be a nutcase to spend over $5000 on an amp for dynamic headphones. But that’s a given that I lost my sanity when I picked the Onkyo A800 as my favorite headphone. The Allnic HPA-5000XL amp is not even fully burn in yet and I still think this amp kick ass lol. I can’t wait until I get to that 300 hours mark . I also like to burn the amp while listening so that my Allnic adventure ending will taste even sweeter rather than taking the shortcut of just leaving my amp on all day. Plus, I don’t think its a good idea to leave a tube amp on all day.
