Will KEF sell their new sound absorbing technology so others have a chance? IF it does what it says it would open up a lot of box speaker designs for me that I typically go out of the way to avoid given the options. HE was adroit enough to also appreciate Ohm Walsh speakers after all (which uses a "tuflex" block to absorb the backwave in the Walsh style driver which is itself a totally different beast from most "box" speakers in terms of how it operates.for the better I would say). On the other hand if Guttenberg says 10 versus 6.5 as he describes, that’s the bottom line. One would expect the speakers could get warm with all that extra energy converted to heat. Absorbing most of the backwave as advertised sounds really good, but would like to see some tests to confirm the effectiveness advertised especially compared to the alternatives. I was thinking of getting an external node to hook into MF, and that would have put me at about the same price as the NAD.From what I read about how KEF has always gone about applying technology very meticulously and fairly openly with the ls50s ( a big reason why I bought them ie what went into the impressive design was published and made very transparent to any interested buyer), my gut tells me this may well be the real deal and should upgrade my ls50s given the modest cost difference.Ĭould it be hype though? IT’s gamechanging technology if the hype is true. But I really wanted a two speaker outs (a/b), a headphone jack, and some more digital inputs, plus Dirac, and the integrated bluenode. I also auditioned a Musicial Fidelity 2si, and almost bought the 5si. I know I probalby could have probably gone with a little less power, but can't find the C389 anywhere yet. TL DR I bought the NAD C399 and I'm even more blown away by the sound. That got me more curious and into the wormhole. I got the Marantz 7025, plugged it to the pro-outs of the AVR, and I was inttantly blown away by how much more bass and better sounding they were. ![]() Since I listen to mostly musice, I didn't want to have the sub bouncing on my neighbor's all the time, so I started experimenting with Direct Mode, and then all the reading about how power thirsty the Metas are, I decided to add a power amp. So, my journey with the Meta's started using them with a Marantz NR1510 AVR + sub. Howdy, I bought a C399 yesterday and have been A/Bing it with some B&W 706 S2s. Interested to hear from people that have the Meta's and what amps you are using? This seems like it would be almost as convenient as the Powernode and with adding flexibility to swap out things in the future. It's my understanding the regular node can be used as a preamp for power amp. In the search for more affordable amps with more power I have come across things like: Look for an alternative amplifier for the LS50 Meta's.Keep my the existing NAD D3020 V1 with the LS50 Metas and add the node, which would still provide convenience for other users.There is still the nagging feeling of being stuck in the Bluesound ecosystem and no options to swap out or upgrade separate components if something breaks. Although a single box is very convenient and much more acceptable at home and much easier for others to use. The Node is certainly very convenient and replaces all three of the separate boxes in my existing system. Others suggest very expensive £/$1000+ amps from the likes of Nain, Cambridge, Lyngdorf, Hegal and Arcam, which are all out of my budget right now. There doesn’t seem to be much consensus online about amp pairing apart from more power being better for the Metas? But then again Steve Gutenberg mentioned that he tested them with a Rega io, which is only 30w. I need to do more listening over the weekend. I guess because these are both class D amps, although the NAD is only 30w per channel compared to the Powernode's 80w. I expected to hear a bigger difference in the sound between these two setups, There is a difference, but it's not that one setup sounds better than the other. ![]() With this combination, I'm also able to run the DSP plugin and test out the room correction. I have also connected the Meta’s to my existing setup which is a NAD D3020 V1 which is connected to a Allo USBRIDGE SIGNATURE PLAYER running Volumio connected to the iFi Audio ZEN DAC. To my untrained ears, it sounds pretty good, so it's hard to know what I’m missing. I’m currently demoing a pair of Kef LS50 Meta’ with the latest Powemode at home, but I get the feeling from my reading that this pairing isn’t really doing the LS50’s justice.
