Thx for your response. Unfortunately I need everything. I stream tidal. I have multiple headphones, from Clears to hifiman ed x, no iem. Need Bluetooth with my Bose. Also play a dap through my marantz reciever in a small listening room with nice speakers. So I guess it would be the best all arounder. From what little we know. Which dap might be the best all arounder?
I think you have to look at what is important to you when trying to choose a DAP that's best for you.
The Hiby R6 Pro has a lot to like. They've demonstrated to have one the most responsive user interfaces in the industry. Hiby is going to perform closest to a modern day Android Smartphone. So if that snappy user experience is important to you then Hiby is a solid choice.
Some Hiby R6 users have experienced WiFi signal issues. We'll see if the R6 Pro has fixed these poor signal strength problems as users from their user group have reported. We'll have a better idea once its released and more people start using the R6 Pro.
The R6 Pro had impressive balanced output power with 750mw per channel. That output will sufficiently drive a wide variety of your full size headphones vs other current DAPs in the market.
Now for all the great features the R6 pro has I think the DX220 has some as well.
The DX220 has the swappable amp modules. So depending on your output needs you have a wide variety to choose from. As they release new amp modules you can upgrade the amp stage without having to replace you whole DAP. Power wise I think the 4.4mm AMP8 with the 6.2 vrms output should give you a similar power output to the R6 Pro's 4.4mm balanced output. iBasso doesn't publish output power measurements under a certain load (32ohms, 300 ohms, etc) like a lot of other DAP makers, so it's hard to compare. The new AMP9 with tube stage should also be a great match for high impedance/power hungry headphones. As far as Power output I think you'll be covered with both of these DAPs. iBasso gives you more flexibility with its variety of swappable amps. They are the only ones besides Fiio and their flagships that offer this future proof option for your amp stage.
I think iBasso has the better hardware controls layout vs the R6 pro. It's personal taste, but I like volume knobs. Hiby unfortunately doesn't have one. I also prefer headphone outputs on the bottom vs the tip of the device. Others may disagree or not care, but these are small things that make a difference in overall owner satisfaction.
I think iBasso does a better job with customer service than Hiby. I had hardware issues with my R3 that I won't get into, but it was a hassle to get it fixed. iBasso is more responsive in fixing hardware and software issues from what I've seen on their forums. Hiby needs to work on taking care of their customers after the sale. They still leave a lot to be desired when it comes to responding to issues. Simple software issues seem to go unanswered and unfixed. On their R3 DAP, I have pointed out several small interface issues that they have yet to fix. The roll out of their Android 8.1 Oreo upgrade for their R6 customers was a nightmare. In contrast iBasso had a much better upgrade process from Android 6 to 8.1 with their firmware update for DX200 /DX150 customers. So if customer support is important to you, I think iBasso is the better choice.
As far as connecting to your Marantz receiver both have line outputs on their amps. IBasso has some modules that don't, but their current stock AMP1/AMP6 modules do that ship with their current DX200/DX150s. I am assuming the standard amp module they will ship with the DX220 will have a 3.5mm line out.
Both devices have standard built in line outs for digital coax. So no major advantage there to either.
I'm not going to give one a leg up in sound quality as everyone has their own preference and I haven't heard either device yet. Both companies have been praised for their sound quality on their current devices by lots of HeadFiers and reviewers.
Hiby has their MSEB EQ tuning which a lot of people like.
Others on this forum can probably give you their sound impressions of the current DX200.
IBasso had initial lag problems in their UI when skipping to and playing tracks in their early release of their DX200/150 models. I think they've addressed this on their firmware releases and with the help of Lurker. If they can come out of the gate with a snappy UI that is close to Hiby's R6 and keep the price under $1000 they'll have a real winner on their hands.
A Google Playstore preinstalled would be really nice for those that aren't savy enough to load Lurker's firmware. We'll see how this all plays out. I think we have a real battle on our hands between the DX220 vs. the R6 Pro. If you are patient and don't need to purchase right now then you'll have a lot of options come this spring. Of course you could always just purchase both! Best wishes in your decision.
