Agora amps are incredible. Makes previous gen feel prehistoric!
The Helix Stadium XL is, hands down, the most inspiring and usable piece of guitar gear I’ve owned. It takes everything Line 6 learned from the original Helix platform and pushes it into genuinely modern territory. The new agora amps have to be played to be experienced fully. They are extremely realistic and hugely responsive, this doesn’t come across as well in the plethora of youtube videos!
The standout feature for me is Focus Mode. It completely changes how fast you can build tones. Instead of menu-diving or second-guessing signal chains, you lock into one block and shape it properly, in context, in seconds. It feels immediate and it encourages you to trust your ears rather than your eyes. Tone creation is faster, more intuitive, and far more enjoyable than on any previous Helix unit.
The touchscreen is excellent. It’s extremely responsive, accurate, and actually useful rather than gimmicky. Dragging blocks, adjusting parameters, and navigating presets feels fluid and deliberate. There’s no lag, no missed inputs, and no frustration. It genuinely speeds up workflow, especially when editing on the fly.
Bluetooth audio is another massively underrated win. Being able to stream phone audio directly for backing tracks, reference tracks, or quick practice without extra cables is incredibly convenient. It sounds great and just works, which is exactly what you want.
Yes, there are some minor bugs at launch — but that was the trade-off for getting such a forward-thinking product into players’ hands early, a vote taken on line 6 social platforms. None of them are deal-breakers, and knowing Line 6’s track record, they’ll be ironed out quickly. I’d much rather have the hardware now and grow with firmware updates than wait another few months. Firmware 1.2 has already released, less than a month after release fixing some bugs and adding more agora amps. Huge work rate from line 6!
Overall, the Helix Stadium XL feels like a proper next-generation unit. It’s powerful, fast, inspiring, and clearly designed by people who actually use this stuff on real stages. Once you spend time with it, going back to older modelers feels clunky and dated. Absolutely worth it.

Brilliant User Interface & Great Sound
I am coming from a humble Pod HD 500 straight into the Stadium XL Floor - although I have used the Helix Native software a bit as well, so I wasn't completely unfamiliar with the Helix sound and effects. I must say WOW , what an upgrade that was! The sounds are of course better - I would say the biggest improvement from the HD series are the cabs section (updated for the Helix around firmware 3.5) and the fact that you can load IRs, which is of course a standard nowadays. The amount of amps, cabs and effects is also a huge upgrade from the HD series.
What's most impressive is how Line 6 has made it a fun and engaging experience to try all the different amps and effects out. They are mostly dialed in pretty well from factory (the factory presets are also mostly great), and Focus View allows you to test completely different tones easily and fast.
The new Agoura amps are impressive - I am mostly impressed with the clean amps. It's not that the distorted amps don't sound sound great as well; they do, but it is hard to beat the Badonk for metal rhythms. The Revv and Panama models are very good as well - but it can be hard to justify the extra DSP, given that Badonk is pretty light weight.
In any case, DSP can still be tight if playing with 2-3 instruments and two Agoura amps per path, so sacrifices need to be made in those cases. Choosing the Badonk instead of one of the Agoura high gain was my logical decision, and it freed up all the DSP I had the need for and probably more.
The touch screen is huge, bright and a joy to use - especially for Focus View, parametric EQ and 10 band EQ. I still have to experiment more with it for the cab block, which seems to work really well as well.
I haven't used Showcase yet, but looking forward to using it for pre-recorded bass for my band's rehearsals. Proxy is not out yet, so I can't speak about it as of yet. I can tell that I am already on the fence about it, given that Line 6 has stated that one capture block should use as much DSP as an Agoura amp. I might be mistaken, but if I remember correctly from testing out the Quad Cortex, I think the capture models on the QC use a lot less DSP comparatively speaking. In any case, I opted for the Stadium for the modelling, not the capturing - but it can still be a great bonus.
All in all I am having a lot of fun with the unit, as well as dialling in some killer tones both with the Agoura models as well as with some of the original models. It was a very expensive purchase, but I am more than satisfied with the results so far.
On a sidenote, I know that the units have come out of the factory with a lot of bugs. Luckily, I have only encountered the disconnections from the computer software - nothing major, and nothing more. Furthermore, a lot of the bugs have been fixed in 1.2.1 - and knowing Line 6's track record, I have confidence that everything will be fixed soon, and new amp models will continue to pop up regularly, which just makes this unit an extra joy to have.

Amazing!
Amazing and massive sounding unit! The Agoura amps are fantastic. I am still figuring out all the intricacies of this machine. Built like a tank!!!

I've been playing guitar for over 20 years and this is my first modeller. I've never really had a good tube amp and my sound comparison is only to my own orange micro terror and a couple of boss pedals and lots of videos in youtube. With that, I just want to say that maybe my ear is just not as tuned for accuracy as someone who owns and has played tube amps for years.
I started wanting a modeller since the quad cortex got out but for all of the big ones (quad cortex, fractal, kemper) there was always something missing.
When the stadium was announced, it ticked all the boxes in my head. Enough footswitches, good size, the scribble scripts, big responsive touch screen for easy workflow without a computed, enough i/o, line6's support history of the previous gen, and very promising sound.
For my use case, soundwise, I'm sure any of the modellers, and maybe even the cheap ones would be enough, but happilly I could afford the stadium and went for it as a gift to myself.
I've been really happy experimenting with it and really love the sounds coming from it. Very intuitive device with thousands of options.
I would recommend this thing to anyone that is looking for a modeller. Showcase is pretty cool for my, to play along songs. The only thing that irritates me is that I though the stem separation for the songs was already implemented, which is not the case, but I'm sure this will come.
Great device for creative sounds!

I love it!
So easy and intuitive to use. I get some great sounds out of this and it's so absolutely beautifully diverse in its sound pallet.
I was between the Stadium, the Quad Cortex, or the Fractal FM9. I bought this because of the showcase features and its ease of use, thinking that I may be sacrificing tone quality slightly, but this thing is fantastic!
