The A70 Pro has quite the power output and is $100 less than the A90D. Besides the more powerful headphone output how does this amp design compare to your A90D? Is this also a discrete design? It appears to have a slightly better SnR. Any advantages/features the A90D has over the A70 Pro?

You confirmed exactly what I was afraid of. I love that the SA-1 is mostly Class A, but it will get old really fast having to pickup my stack everytime I have to switch from low to high gain. I tried low gain on my Jot1 with my HD650s and it sounds underwhelming. Poor dynamics and bass...

Enjoying reading the impressions of the SA-1. I currently have the Jot1 and this would be a nice upgrade. The only thing that bothers me about this amp is the gain switches on the very bottom. I wish they would have just put the low and high gain right on the front next to the low z/high z...

Yes, Cobalt is a good choice! Forgot about their newest option as the DragonFly Black and Red series have been around for a long time. The Cobalt is going to be the best Dragonfly option with the lowest floor noise. These run $299 US. Here's the discussion thread here on HeadFi...

For portable music I would recommend you just get a dedicated DAP. I have the Hiby R5 as my main DAP and really enjoy it. It has a black background and has a very low floor noise according to a number of HeadFi reviewers. https://www.head-fi.org/showcase/hiby-r5.23884/reviews You can order it...

Never had to pay US customs Fees before when ordering from them. If there are customs fees wouldn't the US Postal Service usually charge you before they release your package once it arrives at your local post office? Not sure why there is a fee issue in China. It seems like a delay tactic to...

Is anyone having issues with their L3 order from Linsoul being delayed/held for payment? I just placed an order with them through Amazon US on 4/23 for a pair of L3s and it shows they shipped them. But when I look at the order status it says Delivery on Hold. When I look at the tracking...

Ah I see. You are talking about the fit of the tip on the nozzle instead of fit in ear. I can't find any specs on the nozzle diameter.

You may run into hiss issues with this Xduoo Link when paired with the L3's. Here's a reviewer that tested this and he made the comment about sensitive IEMs. He mentions his AudioSense T800 IEMs which are 9 Ohms impedance. Here's his quote from the article "I feel comfortable recommending the...

What is the model of you Xduoo DAC? Please note I haven't received my L3s yet from Linsoul so I can't test their sensitivity for you right now. I assume by compatible you mean it will pair/match well with the L3s? Any Xduoo dac/amp model with a headphone jack will be able to play the L3s. If...

It really depends on your ear canal and the IEM nozzle size. Everyone has different size/shape ears. Do you have Spinfits on any of your current IEMs? If you don't I would recommend you order a couple of different sizes to see what works best. I have never used Spinfit tips, but I have a...

I'll definitely let you know how they sound on the Jot through the balanced port. I had to order a new balanced cable with the QDC connector with 4.4mm Pentacon for my R5 DAP along with a 4.4mm to XLR balanced adapter to plug into the Jot. The L3 uses that recessed to 2-pin which adds a whole...

Just ordered a pair from Linsoul. These appear to be sensitive IEMs like the Andromedas. Linsoul shows the impedance at 8.6 - 9.5 Ohms and a sensitivity of 108dB SPL/mW. These could be prone to hiss if you are using a headphone amp/DAP with a higher output impedance like the original Hiby R6...

I have had my share of issues with running Qobuz on the R5. I don't have any trouble with the WiFi. Been mainly using a 2.4GHz WiFi connection. Where I have had issues is with Qobuz freezing when I first launch it and try to play a track. The app opens fine, but when I try to play a song...

When I pause the R5 and put it in sleep mode is the blue light supposed to blink? I know this was discussed earlier with the battery drain issues, but I can't find a definitive response. I've enabled all the Google Play and Services. Battery life is decent. I thought someone said the blue...

I am using the 512GB Samsung Evo Select MicroSD Card on my R5 and Galaxy S10+ phone and both are working flawlessly. No issues. You should get 476GB of usable space on a 512GB card. You lose 36GB to formatting. Here's the link of my 512GB cards...

Joe, You're the man!! I reinstalled UAPP and followed your settings instructions above and now I have full HiRes Playback 88.2, 96, and 192kHz over WiFi (green light indicator now appears). Thank you very much!! Enabling the HiRes direct driver must have messed everything up and caused the R5...

I have tried the HiRes Direct driver in UAPP and it will play a couple of songs at native 24-bit 96KHz or 192KHz when streaming Qobuz (green indicator light works on the R5), but then by the 3rd HiRes song it will start to play with annoying constant pops and hiss. As DJ Core has pointed out it...

I have the same fit issues with the Kanas Pro. The shape of them doesn't fit my ears very well. The right side is always falling out. I have tried a variety of tips and the JVC Spiral dot silicone tips (medium small) work best for me. I have tried all sorts of foamies like the Symbio W's and...

As far as upgrading your ancient Sennheiser headphones a few questions come to mind. 1. Which Sennheiser model do you currently have? If you currently have an HD600 or 650, you may want look at an open back planar that an be driven by the R5 to have a different sound than a Sennheiser dynamic...

see below

Just received a pair of AKG K371 closed backs and have paired them with the R5. Can only run them single ended as AKGs aren't wired for balanced connections. Has a singled ended 3 pin-xlr removable cable with a single ended 3.5mm plug for your source. The headphone uses a 50mm dynamic driver...

Thanks! I really like the cable. The material is high quality and flexible. It's about 5 feet long and has a very secure right angle 4.4mm connector. The only nitpick I have is the Right & Left (R & L) connector logos face to the inside rather than outside. Opposite of the Sennheiser HD...

+1 with @equalspeace on the HD6XX and R5 pairing! Got my replacement 4.4mm cable today and fired up the R5. I am at 70/100 volume steps on high gain and I wouldn't want to go much higher on well recorded material. Very impressive that this little device can output this much power on a 300ohm...

So I was all excited to plug in my HD6XX's to the R5 with the new balanced 4.4mm cable I received yesterday. I hook up the cable, hit play, and no sound coming out of the right channel. I fiddle with the cable and still no sound. Major buzz kill!! I check to make sure that the 4.4mm output...
