It's been a long time since I was really impressed by some DAC products after 9038pro and AK4499 came out and flipped the desktop DAC market. Yeah, for the portable side of the game, an implementation based on CS43131 is also a significant improvement but somewhat underwhelming without reaching the threshold of theoretically comprehensible optimum. Kudos to L&P for striving above and beyond, even doing their own SIP to present the best CS43131 implementation with a measured SINAD of over 119 dB.
P.S. The leather case is kind of underwhelming compared to the device.
First, the shipping via DHL is escellent.
And, now, via Iphone+Roon ARC, the sound of a 300 ohms earbuds is perfect to my ears, at the good level.
The L&P sound is there !
I own the LP6ti7AE and my listening pleasure continues with the W4.
The same universe, analog and bright, precise and harmonious.
Stellar spec'ed dongle and MusicTeck shipped it to Europe really fast.
I am big fan of a good sound on the go in a small form factor.That's why I decided to buy another USB dongle. Before I had Lotoo Paw S1 and L&P W2.The first one was quite weak for the sound I was looking for but the W2 was a great success.
I am saying that I was, because now I have purchased from this great website the flagship L&P W4.
This is 10% or more better then the W2 in every single aspect including instrument separation, details, soundstage, sub bass.
I can't compare it with the other high end RU7 as I haven't heard it, but the W4 is very detailed, neutral with a black background, it uses very little battery power from your phone and is very powerful for it's size.
I really recommend it to anyone that is interested in quality powerful sound in a small device.
