XIO Soundbar

KEF XIO hands down. But a bit out of budget unless you can stretch it. Listened to it personally at KEF Music Gallery and was blown away by movie experience but most of all music performance. Very high quality product though at that price you might be better off looking at a high end stereo system instead.

I had the Ambeo Max and currently have the KEF XIO, agreed. Technically the KEF XIO pushes more watts but since the drivers are smaller it’s probably a wash.

I was on my 3rd Sennheiser Ambeo, all of them bit the dust; First one had audio dropping out and crackling, second one had a literal puff of smoke when the center channel went out, and most recent one was failed boot loader message scrolling on the front display (inoperable). Factoring in the cost to replace and the experience I’ve had since I bought the original one in 2019, I didn’t want another one.

Just the issues I mentioned above, mostly. The first 2 I had creaked quite a bit in use (the chassis) but the 3rd not so much, and I didn’t have connectivity issues for HDMI, sub, or airplay. The HDMI ins are old (not 2.1) for the Ambeo, and the most annoying regular issue was it would freeze up every 2-3 weeks requiring a hard restart. Since there is no switch that physically cuts the power and the power cable is hard to access on the Ambeo, it was easiest to reach behind the tv stand to physically unplug and plug back in.

Currently I am enjoying my XIO Soundbar with the Kube 12 I already had. The Bass is already great without the Sub, but for the real low depth with mainly Movies/Series it enhances it further. It surpasses any Soundbar I've ever tried and it surpasses all "main" brands in terms of bass and full body sound without the Sub. But adding the Real sub, not the dinky Soundbar Subs most brands have, there's no competition. There is proper channel separation and also with a really wide sound when you use the built in DSP and Upmixers. You can still choose to use it in "Direct mode" but it doesn't sound that great that way. It's just ok and still better than other Soundbars that rely heavily on the Subwoofer to deliver any mid and 'bass' sound. Even during heavy action scenes with Dolby Atmos movies, I can still clearly hear the voices. Yes it gets real loud, haven't used it above 55% volume yet, as that's already really loud.

It doesn't sound anything like the Devialet in a positive way. And to me it doesn't look alike at all, otherwise many soundbars look alike 😅. Not much variation you can have with the boxy "bar" look. There are several others that can be wall mounted the same way. If you check the pictures of the inside the speakers are completely different and the specs are different as well. I don't use Roon, I use Music Assistant with Deezer as source. Currently I am enjoying my XIO Soundbar with the Kube 12 I already had.

Also had the Sony SA-RS5 as Rears and Atmos, but the only advantage was that they are wireless, as I can't put wired speakers behind me. So eagerly awaiting the update to move one of my LSX II sets as Rears. As it was confirmed to me all W2 model speakers will be supported as Rear speakers with the firmware update this Fall. Already have 5x KEF LSX II and 1x KEF LSX II LT across the house for mainly music. One set with a Kube10 and one with Kube8. Rest without Sub.

What source are you using? Is it sending the signal with Passthrough so the full decoding happens in the Bar? You can check in the KEF Connect app which Codec is received over eARC. Keep in mind that Direct mode might not sound great if the source is only Stereo. Standard mode is advised + Calibration for the best Surround experience. You can select either Dolby Virtualizer or DTS Virtualizer. Do keep in mind if the source is Dolby it cannot use DTS and the other way around. This is a limitation enforced by Dolby and DTS. If your source outputs LPCM it can use both. I haven't had mine above 55% yet and I thought that was already too loud for heavy action scenes in movies. Am normally between 25%-45% depending on the source of the material i'm watching. I've heard noises coming from all around me with Dolby Atmos movies from different Streaming services like Disney+ and Netflix. I've had the Arc in the past and that sounded like shit compared to this. Very thin center channel, without adding a sub bass to the center channel it sounded way too thin. While with the XIO all the voices are clear and full directly from the Bar.

The neutral sound profile does but the separation still isn't that great. Might be a different story when they release their rear speakers and there's also talks that they might allow fronts as well. Currently it's a bit buggy and a bit light on creating a nice bubble but I'm sure Kef will sort it out. Sony Bravia quads are still leagues ahead if you don't want to go wired.

I got a XIO and set it up today. What are your thoughts on the sound profiles and virtualizers? I find direct mode more natural sounding and DTS virtualizers sound better than Dolby. Dolby is very soft vs DTS virtualizer.

Hard to answer a sound question as I don't know what you are hearing and what you are expecting. Out of the box mine was noticeably better sounding than the Sonos Arc it replaced. In respect to the virtualizer I noticed DTS is louder in my testing but honestly I would like more information on the virtualizers.
