Fiio K5 Pro vs Topping DX3 Pro

Show
I bought some HD 800s, found out my ROG throne doesnt have the right size headphone jack for both the cables. I know I could get a cheap adapter, but id thought I would use this as an opportunity to get a proper amp / dac for them.
The problem is I dont really understand amps / dacs. Could someone recommend me for around $500 aud or less some hardware to properly drive these cans? This is the website I use. It will be used with my PC
Thanks so much
With your budget, and what is in stock on the website, I suggest these options:
I have deliberately not made suggestions towards the upper limit of your budget should you change your mind and are outside the returns window. The depreciation on audio gear is high. Just check out second hand prices online. Or retailer discounts / customer returns sections Oooooh look over there

What made you go for HD 800S?
Is your main problem that your current setup has a small headphone connector and your headphones have a large connector? If so, then do try an adapter. I use these all the time without issues.
On the other hand, if you know that your current rig doesn't give you the sound you want, then look at the recommendations from @Steven.
As you live in Australia, you might consider contacting a dealer as well. No experience with them personally, but Addicted to Audio carries Topping, Fiio, Lake People, Schiit, and iFi. All good brands. Given current supply shortages, ask if desired items are actually in stock.
In this review, I’m looking at the TOPPING DX3 Pro+ Bluetooth DAC/Amp. The DX3 Pro+ is an updated version of the DX3 Pro and comes with an ESS ES9038Q2M DAC chip and Bluetooth 5.0 with LDAC and aptX HD support. The DX3 Pro+ comes with a host of improvements, including lower THD+N (DAC), 85% lower THD+N (HPA), more power and lower input impedance. Let’s dig in.

TOPPING DX3 Pro+Product features
Packaging & AccessoriesThe DX3 Pro+ comes in an understated, clean white box that’s almost bare apart from the TOPPING logo on the top. Inside the box, the DAC/Amp is seated securely in a soft foam insert with an additional foam pad on top. Here’s what’s included in the package:
DesignThe TOPPING DX3 Pro+ is available in either black or silver. It has a rectangular chassis with gently curving concave sides. It’s a fairly small unit, with dimensions of 6.5” x 4.7” x 1.5” (16.5 x 12 x 4 cm). On the front panel are the 3.5mm headphone jack, large OLED display and volume knob/multi-function button. On the back panel are (from left to right): Left and Right RCA outputs, dual coaxial inputs, optical input, USB input, Bluetooth antenna mount and DC15V power socket. The display is large and easy to read. The selected input mode is shown in blue and everything else is a warm orange colour. In terms of what information the screen shows, it tells you the currently selected input, the output mode (headphone amp, headphone amp + DAC, DAC, and preamplifier) the volume and sample rate. The front dial/button controls the volume. In addition, a short press on the button cycles through the input modes and a long press powers the unit On or Off. All of the other functions are only available via the included remote control. Using the remote, you can mute/unmute, change the volume, cycle through input modes, select the digital filter mode, set the gain mode, change output mode and set the brightness level of the display. InternalsInternally, the DX3 Pro+ is centred around the ESS ES9038Q2M DAC chip. An XU208 supports up to PCM32bit768kHz and DSD512 native via USB. For Bluetooth 5.0, the DX3 Pro+ utilizes a Qualcomm QCC5152 chip with support for LDAC, aptX LL and aptX HD. Unlike a lot of Bluetooth DACs, the built-in DAC on the QCC5152 is bypassed and the signal is decoded by the ES9038Q2M. There are 2 gain modes available (+6dB/+19dB) making the headphone amplifier suitable for anything from sensitive IEMs up to demanding full-size headphones. When it comes to output modes, the DX3 Pro+ can be used as a headphone amp, headphone amp + DAC, DAC, and preamplifier. This gives it a lot of versatility for the desktop, letting you drive not only IEMs and headphones but speakers as well. 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 PerformanceThe DX3 Pro+ is basically a plug and play device with both MAC and Windows computers. However, some ASIO functionality requires the installation of the customized Thesycon ASIO driver for Windows. Basic functions are easy to operate using the multi-function dial on the device while everything else is simply done via the remote. 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. SetupGear used for testing includes: For my testing, I had the TOPPING DX3 Pro+ connected to my Windows 11 PC via USB. The KALI LP-8’s were hooked up via RCA to XLR cables. I played a variety of FLAC and DSD files with JRiver Media Center and Foobar2000, along with some playlists on Spotify Premium. For the majority of testing, I left the filter at its default setting of 3 (Fast roll-off). SoundFor a long time now, it’s been hard to fault TOPPING DACs when it comes to digital to analogue conversion. The measurements such as THD+N just keep getting consistently better over time. But thankfully, that doesn’t mean that DACs like the DX3 Pro+ lose any musicality or sonic character. The DX3 Pro+ sounds cohesive and expressive whether you’re feeding it absurdly large DSD files or streaming from Spotify. Obviously, you need to use high-quality files to get the absolute best fidelity from a DAC like this. But at the same time, you’re not going to feel disappointed if you’re streaming files via Bluetooth. Either way, the DX3 Pro+ will impress. As indicated by measurements directly from TOPPING and third-party testers, you can expect the DX3 Pro+ to have a wonderfully neutral and distortion-free sonic presentation. And that’s exactly what I hear while listening to Aaron Copland’s “Quiet City”. The dynamics are powerful – the details and subtleties are all revealed. The soundstage is concise and precise – paired with the Kali Audio LP-8 speakers, I’m surrounded by the music in exquisite detail with pinpoint instrument placement. It feels grandiose and spacious; almost as if I were sitting in a grand hall instead of my small room. Firing up The Pineapple Thief’s “Tightly Wound – Acoustic Version”, shows that along with its neutrality and transparency, the DX3 Pro+ is also a master of timing and timbre. The piano notes are crisp and resonate with a natural decay. Each note of the acoustic guitar reveals both strings and the body of the instrument with lifelike density and airiness. The tentative vocals are presented with clarity and vulnerable purity. Speeding things up a bit, when playing “Harridan” by Porcupine Tree, the DX3 Pro+ flexes its ability to drive rhythmically and react swiftly to pace changes. The electric guitars bite with a gritty power and distinct leading edges while the manic drums of Gavin Harrison beat with tidy precision. CompatibilityWith its low output impedance plus high and low gain settings, the headphone amp section of the DX3 Pro+ is a great match for a wide array of headphones and IEMs. Listening on the Hifiman Sundara, the DX3 Pro+ is dynamic yet subtle, detailed but smooth. There’s gobs of power available and I found myself listening at around -25dB in high gain mode. Levels on the DT990 Pro were about the same, maybe a couple of notches higher at -24dB to -23dB. Plugging in the Moondrop KATO called for low gain mode and I spent most of my time between -38dB and -32dB. This is a wonderful pairing, resulting in a clean, dynamic and punchy sound brimming with musicality and detail. Switching to the FiiO FH5s reveals even more details and a wide, expansive soundstage. ConclusionThere are few DAC manufacturers that I hold in as high regard as TOPPING when it comes to delivering high-quality affordable DACs. The TOPPING DX3 Pro+ is a perfect example of why that is. You’d be hard-pressed to find another DAC/Amp in this price range that can express itself so effortlessly with such transparency and musicality. Oh, did I mention it’s also got Bluetooth? Yeah, this one gets recommended.  Specifications
