Does anyone have a preferred Bluetooth solution?
So far I've only tried the UP5 and the W2 with the m0
UP5 is convenient. LDAC, 4.4, low latency, gets me 7-8 hours
W2 and m0 sound so much better, LDAC 4.4, but only good for barely an hour.
maybe LP need to provide a w3 with bluetooth and the sound of w2.

but to be honest, I am not sure why you need Bluetooth with w2, I always put it with my phone. If you really need something with a bluetooth, how about a small mobile phone just for listening. My friend use his w2 outsides, then he bought a second-hand sharp R2C just for w2. Maybe you can take a look on a small phone with the usb-c.

just preference:) ive had it on my phone for the first few months, but my usb c port on my note 20 ultra has been finicky lately, I also like having the phone free from cables now that I've tried it using Bluetooth, especially when working or when I'm out and about.

that's a good idea I'll take a look :) thanks!

So this just in, I've been eyeing on the W2 for a while and was about to buy one. L&P just announced this today, supposedly a new revision of W2 called W2-131 being released but using CS43131 instead of CS43198 due to the chip shortage? So now I'm not so sure about this one, whether this is better than the current W2 or not since it uses an "inferior" DAC (CS43131)?

今年年初发售的乐彼旗舰级小尾巴W2,一经上市就受到广大烧友的喜爱,但,受到全球芯片紧缺影响,W2长时间面临「产能困难」的问题,如今CS43198芯片告急,W2也即将售罄。为此,我们在确保W2 CS43198版少量货源正常发售的同时,也通过CS43131芯片研发出全新版本,希望能够『榨干』这块旗舰DAC

L&P released it's flagship W2 USB DAC dongle early this year, and it's has been well received by many audiophiles. However, due to the global chip shortage, W2 production capacity has always been limited. With CS43198 DAC chip supply getting scarcer and scarcer, W2 is getting harder to produce as well. While we are still trying to produce as many originally CS43198 based W2 as we can, to address the chip supply issue, we have developed a new version of W2 based on CS43131 and hopefully we can maximize the new DAC chip performance as much as possible.

I am wondering that new W2 will have one CS43131 or two, but I think it is more likely to be two chips, or they should call it W1-131.

How about the CS43131, a flagship? better than CS43198?

Exactly my thought, hopefully someone can chime in and provide us with some insights on this. Otherwise, I would stick with the OG W2.

Thank you for the info. L&P also released this OTG cable. I couldn't find much info but it seems to be priced at around $100.

When I saw the info about the chip change, I was glad I already got my W2. (Just 3 days ago.) Not that I have any idea what the effect of the change might have, cause I don't, but I like it so much the way it is. And I really like the c to c cable that came with the W2, which is now black and has a usb logo on one end, and L&P's logo on the other. The connection at both ends is very tight and very stable. No disconnects as yet. Could change though. And $100 for a 6 in. usb cable is definitely a bridge too far for me.

Spec difference between CS43189 and CS43131 are actually very small. Most of number are basically identical between the two. The difference is really in that CS43198 is a DAC only chip while CS43131 is a DAC+amp chip with built in headphone amp section (though the built-in amp is pretty weak). However, it is likely L&P will add extra buffer stage to CS43131 to increase its output power. Remember, L&P actually managed to push W2's performance over than of CS431978's official published spec, so they might just as well push W2-131 over CS43131's official published spec.

Maybe now we can "triple-amp" it... :wink:

The chipsets are pretty similar and have identical specs. Difference is the CS43198 is a stand alone dac and the CS43131 is a Dac/amp combo.

Now obviously you have more control over the sound with using your own amp setup with the 43198, especially with an experienced dap maker with talented engineers. The flip side is usually amps that are combined with the dac are very efficient because they're designed by the dac oem.

The LP team achieved higher parameters then even the theoretical ceilings from the 43198. Givin the architecture of the 43131 I don't see how that's possible 🤔 but I'm not an audio engineer 😉

Not that any of it matters as the numbers are already well beyond the limits of human hearing. Like when somebody says a 768 kHz file sounds better than 384 kHz sampling lol.

The real important numbers to me are imb+noise and image rejection and power swing under load snr. Those ultra crazy numbers dap makers post like snr of 131db are without load.

Pretty meaningless. However the good news is W2 performs great under load.

Ha ha I was typing basically the same thing while you were.
