The Luxury & Precision W2 is one of the better USB DAC/AMP dongles I have tried and the price/quality ratio is very nice. It also offers a whole lot of tuning options and it has a nice little screen on top of it. If you like a full-bodied sound with a high level of technicalities as well as bigger bass and easy treble, and that is delivered in a smoother and warmer way, then the L&P W2 dongle will be perfect for you. In terms of output power, the headphone amp pushes 1800mW x2 @32Ω THD+N <0.1%, 900mW x2 @64Ω THD+N <0.1% and 250mW x2 @300Ω THD+N <0.1%. The line out delivers 2.1Vrms @0dBFS with an output impedance of 20Ω. Functionality & Bluetooth Performance Pairing to the DX3 Pro+ via Bluetooth was super easy on my Sony NW ZX-300, iPhone and Pc. LDAC was selected automatically with my Sony DAP while I was restricted to AAC when using the iPhone (damn you Apple)! The Bluetooth Audio quality is fantastic, especially when using LDAC or aptX HD.

Topping DX3 Pro+ Review - Headfonia Reviews
The DX3 Pro+ bass doesn’t carry a lot of weight in sending deep notes but keeps a tight image not overly emphasized and well managed. Depending on the song, this region can get a bit unexciting although it tells how it leaves the lower region untouched if not for its slight cut-off in the sub-bass which pulls the room-filling energy of drums. I also think that the original K5 Pro wouldn't switch between the headphone/RCA outs automatically, it would just play through both, so you'd have to turn the volume down on speakers when you wanted to switch. That would be a possible dealbreaker for me, but I don't know if that was changed for the ESS version, I can't find any solid info on that.
Features & Specs
The heart of the unit is the AKM AK4493 DAC chip. This is a departure from most of the Topping DACs (and many Chinese manufacturers) which use ESS DACs. Midrange is crisp and tend’s to focus more on upper frequencies, with lower-mid being somehow undersaturated for some. Also, the focus into the upper midrange result’s in a very detailed, crisp sounding vocals. Built in screen is a joy to use and to navigate all options this small device has, whether you want to change volume, input, output etc.
DX3 Pro+, or Something Else Just For An Amp? Topping L30, DX3 Pro+, or Something Else Just For An Amp?
Usage is around 90% on PC thru USB and 10% on gaming console thru optical. RCA possibly with turntable but it would be somewhat niche activity. PC usage includes roughly equal parts of gaming, movies and music listening from a very wide range of genres.The Cayin RU7 has a tuning which is more to the neutral side, but with its full body and powerful, controlled bass impact, it is a very musical and engaging DAC/AMP dongle. Once again, the brand didn’t reinvent the wheel and took all the good points found in the basic and plus version, and polished them. Balanced circuit with a 4.4mm output, Bluetooth chipset, no more channel imbalance, and the same sound signature. Add a mind-blowing bundle with an excellent price/performance ratio. I had to turn the subwoofer gain up a tiny bit - around 2-3 degrees of the rotary gain control. The mids are more forward. Vocals, once again, are beyond imaginably good! Listening to Lindsey Webster singing "Those Three Words", it seems like she's in my listening room! Vocals are very, very smooth. Now I hear the 'velvet sound' of the AKM DAC chips in the DX3 Pro. Treble is a little further away. Pausing the music and holding my ear to the speakers and subwoofer, all are 'dark' with no interference noise. Soundstage is a little narrower than the D50 (as was the case with my headphones system), and instrument separation is less too. Overall, the sound is very musical and great for me as I work from home a lot so it's lovely to listen to for several hours a day. It's nicer to listen to for long periods - less fatiguing. In the heart of the device, there is a well-known Sabre DAC chip ES9038Q2M. That’s a change from the original model that was using AK sourced DAC chip. The amplification section is also revamped and now offers almost twice the power compared to the original. With 1800 mW into 32 Ohm and 250 mW into 300 Ohm loads, nobody should feel wanting for more. XMOS XU208 powered USB input supports up to 768 kHz PCM and DSD512 native. If you’re into wireless, Pro+ supports LDAC, AAC, SBC, APTX, APTX LL, and APTX HD protocols. Sound (Headphone Out) There is USB input of course and Toslink. For coax input, you actually get two of them! So if all of your sources are digital, you have a nice little pre-amplifier on your hands.
Great Deal
