Update on my “endgame Onkyo A800 setup LOL”. I added the LOL at the end because with the Onkyo A800, there is no limit, thus no endgame. The only endgame with the Onkyo A800 is your imagination and resources. If you got a lot of imagination and resources, you can easily take the Onkyo A800 to the next galaxy and beyond.
I know my previous post, I said I pretty much quit headphones because the Onkyo A800 + Allnic HPA-5000XL is all I need. That is true so far, but I found some new magic on the Onkyo A800. So I basically quit collecting headphones to focus more on my 2 channel speaker setup. I bought a Supratek Cabernet DHT with EML 45 Mesh Tubes and a Schiit Vidar 2 for my Polk Reserve R200. Sounded amazing as I knew it will be. Obviously going to upgrade the Vidar 2 to a Tyr when I got more funds and either upgrade the Polk R200 to a L200 or something else. But enough of this speaker talk, back to the Onkyo A800.
So, back in November 2022, I had a gut feeling with 45 tubes + Onkyo A800. Gotta say, it feels good to be right on my gut feeling

. Through sheer curiosity, after using the Supratek Cabernet DHT on my speaker setup, just did some quick connecting to the Allnic HPA-5000XL. Then proceeded to connect my Onkyo A800, turn the volume up and press play… I am glad I moved on from headphones, because the Onkyo A800 is truly 1 of a kind. And this 1 of a kind headphone will always be my favorite experience in headphones. The Onkyo A800 is already known for its natural timbre and it’s ability to replicate the artist tone. We all know that. But imagine, with the power of 45 tubes and just any 45 tubes, but the EML 45 Mesh Tubes and what you know with the Onkyo A800 natural timbre and it’s ability to replicate the artist tone, the just DOUBLE IT! Oh my god, it sounded so real, it just feel so unreal. Does that make sense? I just couldn’t believe what I was hearing. What I thought I knew about acoustic/electric guitar, vocals, snare drums, and bass guitars, the 45 tubes + Onkyo A800 will give you a reminder of this is what it’s suppose to sound like. It’s just so authentic and natural, it actually spoil me with my other headphones. Onkyo A800 and speakers is all I need. I knew the 45 tubes was going to be good, but I didn’t think it would be this good. It’s so shocking how magical the 45 tubes are in the midrange and how crazy good voices sound on these. Not to mention clarity gets another buff and clarity on my setup right now is just too insane, I think anything will sound clear on my setup. Bass hasn’t been affected negatively, I believe I got a good buff on it as well as I feel the bass tighten up a bit thanks to the Supratek Cabernet DHT. It could be all placebo, I’ll still take it because I am one happy camper. The Supratek Cabernet DHT + Allnic HPA-5000XL + Onkyo A800 is a fantastic combo. Supratek Cabernet DHT preamp for its magical 45 tubes and huge buff in timbre, Allnic HPA-5000XL for the minimum distortion thanks to its all nickel core transformer for a more clean sound output, but still has a little more musical sauce with its tubes, and then the Onkyo A800 being the main star of the show with its one of kind experience that you will not find in any other headphone with its natural sounding beauty.
This might be the last update since I move onto speakers, trying to search for the Onkyo A800 of speakers AKA a speaker that sounds natural and can perfectly capture the tone of the artist. If I found anything cool with the Onkyo A800, I will try to post something here. But I doubt it, this might be the last post for real this time. Just in case you do not here back from me, a little bit of parting words. To me Onkyo A800 is THE headphone for realism and it’s ability to replicate sounds to sound naturally. There will a better headphone for bass (which will be hard against the Onkyo A800), clarity, soundstage, and whatever is your cup of tea. BUT, if you are looking for Natural sounding headphone for your acoustic instrument music or a headphone that shreds in rock music or a headphone that perfectly capture the beauty of the human voice. Look no further, the Onkyo A800 cannot be beaten. And if you own a Onkyo A800, you owe yourself a favor and trying the Onkyo A800 out with 45 tubes in a DHT preamp or amp if you could find one
