Can you try and see if it connects to windows 7? Thank you.
Given the amount of Win7 users in China I think the answer should be yes, but let me ask them and then get back to you.

Would this be able to power the LCD-3 fazor well?
These are the output power numbers:
32Ω 235mw
Single-ended:
32Ω: 125mw

Maybe you can check the specs of the LCD-3 to see if this is powerful enough or not.

Thank you.
Just got back from LP China. Yes it is compatible with Win 7. All you need to do is to download a driver from their website.

Hi everyone, before ordering the L&P W1 was wondering if it would be an upgrade over the Qudelix 5K and E1DA9038 that I already have, or would it be more of a side-grade?
Planning on using it with an iPhone as a source for portable listening.

It would depend on what kind of IEM/Headphones you have as well. 5k is self powered, while usb type dongles are very dependant on your source, they will play better if connected to laptop instead of iphone. I had 5k and sold it as I did not find much of the use with their EQ app, some of Lotoo S1 EQ presets where way better than what I could have achieved while EQ'ing with 5k and it's bluetooth sound did not impressed me. Purely for bluetooth usage UP4 was a clear winner for me, but I'm a fan of detailed though warmer presentation, the ones who likes analytical/forward sound signature can claim opposite. Now comparing 5k to Lotoo S1, 5k itself sounds better in usb dac mode, but against S1 and especially when S1 was connected to laptop it was game over for Qudelix 5k. Sound quality wise you will not achieve huge difference between portable dac/amps, it's more to the sound presentation, maybe 10-15% of an improvement, but for some people it could make a huge difference for their listening experience

Around $300 for the W2 is a bit high, What was the improvement again?
I think what many are missing here is the small increase in power from the W1 to the W2, which in conjunction with the dual dac, should in theory give greater control over the speakers. They are saying that the W2 is equal in performance to the L&P L4 which goes for $699, so at $290, it should be considered a steal!

Are the DAC's in the W2 a different model than the W1? some posts in this thread seem to indicate that? If so, does anyone know what DAC's are in the W2?

It should be the CS43198 chip. I believe both W1 and W2 use this chip.

For those who are interested in measurement graphs of W2~ Credited by L7Audio Lab.

DNR is already beyond the DNR of the CS43198 specs based on its datasheet. :L3000:

Thanks for sharing this!

As a related note, L&P has a very good track record in implementing certain chips/technologies. The actual specs of their DAPs usually beat the specs of the chip itself.
