Audio quality comparison between TDA7560 and TDA7851L - Android Head-Units

Although we've been told that units including audio amplifier with IC TDA7851L are supposed to be better than those with TDA7560, I've compared both official specs and surprisingly those of TDA7560 are slightly better... so I would appreciate some expert to clarify it...
TDA7560 => 4 x 30W at 10% THD (4 ohms), Max output 4 x 51 W (4 ohms)
TDA7851L => 4 x 28W at 10% THD (4 ohms), Max output w x 48 W (4 ohms)
Both include MOSFET audio power stage, according to specs sheet, but you can also read:
- The TDA7560 is a breakthrough BCD (Bipolar / CMOS / DMOS) technology class AB audio power amplifier in Flexiwatt 25 package designed for high power car radio.
- The TDA7851L is a breakthrough MOSFET technology class AB audio power amplifier in Flexiwatt25 package designed for high power car radio.
Does it means that the main advantage for TDA7851 is only to be a 100% MOSFET amp??
Which are real differences in sound between both amps in practice?? Anyone has compared both seriously??
I would sincerely appreciate your advice since I was about to purchase a PUMPKIN CN10-10301B-02A (Specific model for Mercedes A W69 and B W245)
PUMPKIN unit includes TDA7560 and seems to have better customer satisfaction and reviews than other similar alternatives that I've also considered from OWNICE and XTRONS which include the "supposedly" better amp TDA7851L...
PUMPKIN unit is one of the few Octacore units with Android 7.1 and 2 GB RAM + 32 GB ROM that I've been able to find (OWNICE and XTRONS are Android 6 units) and, additionally, it can be ordered through AMAZON prime from my city (Barcelona) with no risk, and that's something I can't do to order OWNICE or XTRONS equivalent units (Available trough Aliexpress or their respective websites).
I would sincerely appreciate your opinions regarding the audio differences and other relevant ones you may consider among these brands (Pumkin, Ownice and Xtrons).
I had previously discarded ERISIN option which seems to be more problematic and with lower quality although they provide more options than other brands...
JOYING seems another interesting option but PUMPKIN, OWNICE and XTRONS seemed better..
Thanks in advance

Hi,
As previously discussed, no discernable differences, you would be unlikely to hear any difference between these specific audio ICs and any of the MTCD manufacturers.
If you're looking at a vehicle specific unit suggest posting for user experience and searching these forums.

If you go back and scan the threads of the last few weeks or month, there is a lot of good info about this topic.
I just installed the Eonon with 5.1 Android OS in my 2002 3 series BMW. I do not have experience with these devices, so I can only comment on this one.
I really like the fit. The speed- even with a quad core 1.6Ghz CPU is not as quick as we'd like. Think Android phones from 3-4 yrs ago. Not bad, but not as speedy as a Google Pixel for example. The big change I could see is if the screen were bright enough to outshine the glare from the sun. I have ordered ant glare screen protectors. We'll see how that works out.
I have a Henharo 4.2.2 based unit. A7 processor. I have to say that unit is terrible. The screen is not bright enough, the sound quality is bad. The well known hissing noise is really annoying. GPS dies sometimes, Also there is no support from the vendor. I'm looking for a replacement. I'm not an audiophile but I like good sound. Ownice C500 looks promising, however I'm not sure about the sound chip with comes with the unit. That's TB2929. The only thing I know is that the chip is made by Toshiba
I have a MTCD made by KGL, all I can say: keep away! MTCD seems like a terrible platform, the quality by KGL is just terrible and their service non-existent.
Have to agree C500 looks very promising. Especially now that people have succeeded in rooting the device, this hopefully provides room for user mods to polish out some of the flaws.
Anyone knows how good Ownice support is.?
I just don't want to ended up with another unit without the vendor support...
You might want to look at the Joying 2GB / Sofia based units. I have had one about 2 months and real happy with it. It seems well made, fairly fast, relatively bug free. Support seems pretty good with frequent software updates, and to reply to emails.
What about the sound quality and that famous hissing sound?
There is one interesting unit I have found on their website: JY-UL135N2
. Newest RAM 2GB Android 5.1.1 Lollipop Auto Radio for Universal Vehicles
. 7-Inch Double 2 Din Digital Capacitive Touchscreen
. CPU: Intel SoFIA 3GR , 4 Cores
. RAM: DDR3 2GB, Flash: EMMC 32GB
. Resolution: 1024x600 display, support 1080P videos
. With the new developed android 5.1 system
. Support PIP, DVR, OBD2, DAB+, NFC, Bluetooth 4.0, RDS, etc.
Just the thing which bothers me is the sound quality. The unit I bought has way worse sound than the stock radio.
That Joying unit's sound processor is TDA7388 - is it any good?

It sounds good to me, much better than the stock unit that was replaced. No noticeable hissing or any issues. Only downside is no controls for the sub on the equalizer.
oh that's a problem for me. I have an infinity sound system in my car. That Android unit I got installed was just terrible. I pulled it out yesterday and sent back to the seller. I'm kinda picky in terms of the sound quality. (not an audiophile though)
Are there any mosfet based units available?
and also any word on Newsmy NR3001 unit?
@slav.z What did you end up getting?
JY-UL135N2. All works . I didn't update to 6.1 though. Not a fan of untested firmware.
Your Joying JY-UL135N2, will it support third party usb camera, and can you use third party usb camera apps with it like Carr O.
I will NEVER buy another as the SH*TS crippled Android to only work with their usb camera, and locked out other apps from using their camera.
Can you confirm open usb camera?
Hi, there, you must visit this link the site suggest 10 of the best android auto head unit, just read the full article and you will find what are you looking for
I had ok luck with Joying, sound was better than my stock unit, my only real complaint is slow boot and app launch time. 2-3 mins from power on til Spotify plays, or GMaps track my location.
UP
s190 are great imo
Startup is 25 seconds, or it can be put into Auto Sleep with instant On which says only uses 9mA

Recomendations Dasaita V Xtrons

I am going to replace the factory head unit in my 120 series 2006 Prado and would love some advice.
I have had an Erisin double din unit that is around eight years old now and has performed really well apart from the lack of memory pushing the GPS to the edge although for the most part it coped OK.
I am interested in a PX5 based unit and would prefer knob controls, but these seem thin on the ground in the 200mmx 100mm to suit the Toyota.
I am interested in the Dasaita HA2135-V840-8 due to the comments about the quality of the chips for bluetooth and radio etc, but not convinced with the lack of DVD, and DAB+ support.
The Xtrons PB78HGTP looks really good, but lists the display as 800x480 compared to the Dasaita's 1024x600.
I can't find any definitive info about Xtrons chips, but like the features of the unit more that the Dasaita's.
The Xtrons PA77HGTP has my preferred control layout, but would the PX3 be disappointing compared to the PX5 units.
I am not yet allowed to post links but they can be googled easily
Any advice would be appreciated.
Thanks

Would like your opinions regarding head units for Subaru.

Hello ))
I'd like to purchase a head unit for my 2009 subbie, and i found some head units on aliexpress. Lookin in the 300$ range, there are some decent options but nothing seems perfect.
Here is what i have found so far:
- Intel T8 platform idoing with tda7850 and nxp6686. built in DSP. low screen rez tho (1024-600P) and android 9.0 which i guess is okay - https://www.aliexpress.com/item/32950726060.html
- Same intel T8 platform with tda7851L and nxp6686. built in DSP. high screen rez of 1280-720P android 10. Seller seems a bit unsupportive by people's comments tho.. Responds fast, but ignores if you need to solve an issue. https://www.aliexpress.com/item/4000923381907.html
- Also T8 platform with tda7851 and nxp6686. built in DSP (2 channel video, 4 channel audio), 1280-720P android 10. Claims that his amplifier tda7851 provides 4x 60W (How is this possible?) - https://www.aliexpress.com/item/4000994985279.html
I know that PX6 is slightly better than intel's proccessor. Thing is the that i doesn't support dual band bluetooth and i've heard that over time Intel's overheats less. But again those are thing i've "heard".
Would like to see some more suggestions on what to buy.

Sound Quality on PX6 units with DSPs

I recently purchased a Mercedes 2005 CDI and I gotta say I love this car. The COMAND is solid but definitely outdated. I started looking around for drop-in head units and found the 2 big players Avin and Dynavin for the W211. No looking at older posts (2018 and before) i hear a lot of people beating up on the units because they are Chinese made. But present-day it seems like there have been strides and upgrades in chips that are being used. So I'm wondering is there really going to be a noticeable sound difference between a Bluetooth-connected 3.5 mm adapter going through the command and a properly tuned Avin or Dynavin unit going through a MOST adapter to a factory amp and speakers? Looking at XDA it seems like the chips used in the AVIN is TDA7851F (I am waiting on confirmation on this from AVIN). The TDA7851 is actually the same as a pioneer chip (https://forum.xda-developers.com/t/a...2171s.3891089/). The Dynavin is a burr-brown (or Texas Instrument chipset) now I'm not sure how plays with the most adapter. But in the end, it seems like the hardware is there for improved sounds. Does anyone on here have objective data to swing the conversation one way or another?
The other question is longevity, I've heard the Dynavin units generally have generally received pretty decent reviews and have pretty decent support. I have not heard anything from long-term owners of the Avin. If there are any on here have your units functioned long term?

Best amplifier chip / DSP or not

Hi,
I'm just looking for a new Android head unit for my car, and here's what I found on Aliexpress :
First one is a Seicane branded one, with AC7315 amplifier chip according to the seller, and DSP built-in
Aliexpress Link (Select "WIFI(2G 32G)H5N-RPH" )
Second one is a GiantLion branded one, TDA 7388 amp chip according to the seller but without DSP
Aliexpress Link (Select "WIFI (2GB 32GB) D")
Which one would you think has the best sound quality ? Both do have an Allwinner T3 CPU so it's identical on this point, but I read somewhere about someone having a really poor sound quality with the AC7315 amp, so I found this unit with a TDA7388 but it doesn"t have DSP, so I'm a little lost...
Thank you !
Hi and welcome new member,
Not MTCD or hardware development, requesting mod moves. Allwinner T3 CPU are not MTCD.
In reply, both would be poor, suggest avoiding these units altogether.
Take a little time to read through the forums and familiarise yourself with the forums and unit types.
Thanks for your reply !
I'm sorry I didn't really know where to post this...
I have a good 4 channel car amplifier from Blaupunkt, do you think if I hook it up to any of these units the sound would be better than its integrated amp ? Like can the RCA output also be of poor quality ?
