Can I join you (No MQA club), it would be less expensive I’m sure (40 to 50€) and if I keep it I will not use anyway.Me too
as I only use and tested them with headphones I can not tell you about Its preamp capabilities. For me the dx5 had more "juice" so I will stay with the dx5. But I would pinpoint that difference to the dx5 achiving higher power output in the headphone amp. Besides that I wouldnt say I hear an audible difference between them. as yavormoskov said you should include the sabaj device too, I am thinking about trying it too as it is a bit cheaper and seems to have similar performance. Another reason for me to take the dx5 is that topping seems to be more willing to publish and make firmware updates available. The smsl m500 mk1 had a firmware issue that they resolved but they made it very hard to find it. Its basicaly not on their website and you have to get it somewhere online and that was a big no no for me.Hi, i'm also new around here and looking for a DAC around 350€ to pair with my NAD C 316BEE V2 and Q Acoustics 3030i. I've restricted the choice to Topping dx5, SMSL M500 MKII and also SMSL D300 so please can you share your experience with both. I think objectively they should have the same sound signature the SMSL D300 has a different Chip manufacture so don't know if it will affect sound.
It does remember volumes for each output independently.I had to google for the manual to check for that would be a bad user experience for a desktop DAC/amp: You can double-click on the volume knob to switch output. It does not say if the volume for each output of remembered, which would be nice to have.
This not a behavior I want, though, as only option.
Sorry if I'm wrong but, it looks that you only have fully access to menus by switching off and then switching on while pressing the front button. Not all functions are available through the remote. There's room for improvement from Topping, for me there's just one option I would like to have on the remote, the possibility to change between DAC and Pre-amp modes. The displays "menus" and remote control on SMSL are intuitive "more user friendly". Despite all this the construction on Topping DX5 is better than SMSL M500 MKII and D300, as they sound the same (DX5 in Valve Sound mode) I think I'll keep Topping.That's not correct. I just get DX5 and I can tell you that all settings can be changed without the remote control. But with remote control you can change the settings directly without switching on/off to get into "settings menu".
The DX5 looks great if you only have space for a single-box solution, but for only a bit more, I would consider the E50 + L50 combo. This has, essentially, the same DAC but what I understand to be a more powerful headphone amp with proper balanced output. Depending on your headphone choice, the difference could be beneficial.
I doubt that. First of all, balanced is louder and then you find that better. If you adjust your volume and do a blind test, you would probably not be able to determine a significant difference. Unless output impedance is higher at balanced. This is rather worse for IEMs.My planar IEMs definitely exposed the difference in sound quality from my dongle when I opted for balanced over SE.
The OLED displays in any of these products do burn in over time as they are left on. I have run mine on low brightness for years but it has still faded on all the text where I use it most often. It just is what it is.Do you think these people are not turning OFF their OLED display and that causes the burn-in? How sensitive are these OLED displays to burn-in? I don't think I have a OLED display @ home and so I have no experience with them.
Can you confirm if all the signal op amps are TI OPA 1612A?This is the section of the headphone amp of DX5
Signal amp is using TI OPA1612A Driver is using Ti TPA6120
Gain is switch using relay which is good
According to the datasheet of the Ti TPA6120 the resistor on the output should at least be 10ohm
But topping choose instead to go with 3.3 ohm, So it might not be a good idea to pair it with a headphone with ultra low impendence,
With a resistor if 3.3ohm in series with the output how could they specify the output impendence to be <0.1ohm ?
The rated power from the datasheet of TPA 6120 is 80mW into 600ohm From a ±12-V Supply at 0.00014% THD + N
Anybody knows what NFCA means ? I did not find any global feedback from the output

As far as I can see yes the signal OP Amp are all OPA 1612ACan you confirm if all the signal op amps are TI OPA 1612A?
As for the OPA's the marking's OVII TI 15I (if you google it) it seam's to go to TI OPA 1612A, If you look at the pictures of E50 you can see clearly the marking's of the OPA1612A.As far as I can see yes the signal OP Amp are all OPA 1612A
Have you listen to the Value and Electronic modes ? Can you describe the difference of both which you preferred and how it is different from turning off the sound mode
Yo guys!Hi, i am have issue with MQA tracks (on TIDAL and Foobar2000), then start play or scroll track it make 'clicks' then change mode from PCM to MQA, same as here https://audiosciencereview.com/foru...dac-and-headphone-amplifier.24341/post-902276
this bug or feature?)
Translation of the emailYo guys!
I was having the same issues and I sent email to topping, finally got a reply with v1.40 firmware updates, let’s check is there any improvements!
Let’s check my reply tofuI received my DX5 from Amazon 3 days ago and tested it immediately and found that there were many problems with the DX5's operation. None of PCM, DSD, MQA works properly like the E50 and DX3 Pro + I have used so far.
Pop noise caused by switching to songs with different sample rates or switching songs between DSD and PCM. Occurrence of sound interruption or pop noise that occurs several times at the start of MQA playback. In addition, the volume may suddenly drop extremely and no sound may be output from the left CH. The sound quality is good, but I am not in a state where I can listen to music with peace of mind.
I immediately learned about the new firmware V1.38 and installed it in anticipation, but nothing improved. I will investigate the symptoms a little more and then return it to Amazon.
You will hear a loud relay operation sound every time you switch songs on the DSD. However, this relay sound may not be produced at all while using it. It's a very strange behavior.
* Whenever I receive a DAC product, I use PCM 44.1 ~ PCM768kHz, DSD64 ~ DSD512, and several types of MQA files to check the operation.
