Review: iHiFi 812 v2 portable player - an interesting "budget high-end" portable - Page 5

post #61 of 88

Maybe someone here can help me?

 

I got IHIFI 812V2, and at first was extremely happy with its sound. And then I did something really stupid and upgraded the firmware using this file (which is supposed to be for both 812v2 and 960): http://www.i-hifi.com/hd/960/ihifi164.rar

 

Now, after the upgrade, it seems like something is wrong with it. Everything is working, but it just sounds wrong. The sound is clean, but thin, and the highs are far too excessive, to a degree it hurts my ears listening to it (both with my earphones and headphone). I wish I could revent back to the original version, but I cannot find it. Tried to contact them, but faced some language barriers.

 

Did anyone else here faced the same problem? Or maybe others here are just smarter than me and know better than doing unnecessary firmware updates? Does anyone happen to have a file with the older firmware, or at least can tell me whats the version number you your device?

Update: Problem solved by cleaning the internal memory of the device, and flashing the firmware again. Now it's working flawlessly.
 I am not as experienced as some of the other participants in this thread with high-end equipment, but in comparison to any equipment I have in the past, this thing sounds amazing, IMHO. I used it with my modded Fostex T50RP, I tried it with my IEMs, I tried it with my M-Audio BX5a speakers, and it was a huge improvement wrt to anything I connected to them before.

I just bought one of these from szclever88 on ebay so thought I would add my opinion into the mix.

 

I use the player with a pair of AKG K550 headphones and mostly listen to FLAC files. I am very impressed with the unit, there is a maturity and authority to the sound which puts it in the league of high quality domestic hi-fi rather than the compromised sound I would usually associate with a portable. The sound is just a little on the warm side, but in a good way, it does not mask detail or sound soft in any way and the audio quality from "line out" makes a domestic CD player redundant in most cases.

 

There are a couple (well, perhaps more than a couple) of minor idiosyncrasies with the UI; does anyone else find that the "Freq Chart" always appears after the player is restarted even though the option says "Closed"? And what does MSEQ do? I can hear no difference at all. I should make it clear that I don't care about either of these things, I'm just interested in whether this is the same for all units.

Thanks for posting. I agree with your thoughts on both sound and the UI. 

 

Another device called the HiFi ET MA-9, which runs a nearly identical UI, has a Rockbox port that is almost complete. I wonder how tough it would be to apply it to the iHiFi models? That would be awesome.

I have no idea what the MSEQ is either.
post #66 of 88

I had thought that the answer may be found within the DAC or ASRC datasheet, as I can't think of anywhere else where these preset EQ functions could be easily implemented, but there appears to be no mention of them. The exact same set of EQ options appears to be common to some other portable devices, though.

I think the MSEQ must be a function of the Rockchip SoC on board this device. It's definitely not something with the DAC or ASRC. 

post #68 of 88

Yes, I think you are correct, these EQ functions appear to be common to Rockchip equipped devices. I can't find any datasheets for Rockchip, they seem to be very protective of them.

post #69 of 88

Following a System Restore, MSEQ is now working; "3D" provides a bathroom acoustic and "Bass" sounds as though the next-door neighbors are having a party. So, both completely useless. LEQ does something, but I'm not entirely sure what.

 

This player does sound great, though. I have never been a fan of headphone listening but I can listen to this for hours without fatigue or boredom setting in.

I'm researching which player to get, this one is at the top of my list. How much better is it than a fuze with custom LOD with O2 amp?

Haven't tried a Fuze in that scenario... but the DAC section alone of the 812 is quite a bit better than Fuze. So there's definitely potential.

project86, did you listen to Hisoundaudio Studio-V 3rd Anniversary? If yest, can you compare it to the 812?

Currently I'm considering changing my source from DIY iPod Video Mod to something else like Studio, 812 or AK100 (although I would prefer to pay less), but I'm not interested in Dx50 or X3. New DAP will drive my new CIEMS Cosmic Ears BA4r (which I bouth actually due to yours review project86, thank you).
post #73 of 88

There's a new model they came out with just recently, though you won't get many comparisons to the 3 Anniversary  there unless you are lucky. Maybe someone has heard them both.

 

It's smaller and a bit more refined looking than the 812. Same price-range as the X3 and D50 I believe also.

 Can't hurt to look at an extra option.

Pairing with CIEMs should be your first question though.

Nice update apparently Rockbox works for this, and the 760 and 960. I assume the 960 files were used for this 812v2. ( yes this is confirmed )

 Read a few posts up as well for the file links and thread info but here is the link to pictures of it working

By the way this player is incredibly good. It really is like carrying around a fullsized doemestic hifi thing...

 The right headphones and you can sit back and get lost for hours. First night I had it on for 5+ hours with Fostex T-10.

Boy this 812v2 thing, where to start.....it is realllly good. So good I can't stand using anything else now. The non-portable fullsized amp is sitting there getting mad at me now making me feel guilty for ignoring it.

I keep telling people it is like it grabs your headphones, scolds them for misbehaving,  and puts them in their place  like it is exercising complete contol over them. Don't know how else to describe it. The internal amp is something else quality wise.

No need for any extra amps at all which is exactly what I was after.

 

Interface is ridiculously easy it took about 10 seconds to figure out the buttons.

Nice that it shows a whole pile of albums on screen at one time rather than what i was used to on the C3. Going back to the C3  while this is charging, well it's not that fun.

 

There was mention that this digs deep without being overbearing and pulls out some of the smaller stuff in tracks, yes it sure does.

Been using this during a ridiculous amount of T50rp mod tunings, and at low gain setting with volume near max it is just fine probably just at the edge of that zone where you shouldn't listen that loud for too long ( if you  are responsible that is :ph34r: ).

Normally I use a fullsized Victor/JVC A-X55 Dynamic Super-A amp for mod tunings but the sound on this I would say is at par with that or so darned close I can't tell offhand here. A direct A/b is in order

. That's why I am confident in using it during various trials. This was also mentioned before in here but i really think it needs reinforcement on that aspect of sound quality.

 

 I really have no need of all the fancy extras on the 960 but if it is slightly better in the sound department then it's going to be hard to refuse that next no-brainer step "up".

 

If you are simply interested in sonic ability and have decent headphones ( some do not show much obvious difference, most of mine do ) and iems , and do not mind a simple ui with just the right amount of basics this is something you need to at the very least explore as an option.

Anyone used to a C3 functionality will find this so much more easy.

It is also a fair bit lighter than it looks :bigsmile_face: and speaking of looks i enjoy the utilitarian/industrial style in this build here. Awesome.

No problem sticking it in a jacket pocket ( the included velvet pouch works great also ).

 

Going to pull out the insides next and apply a Screenpatronus silicone screen protector.

 

Now to see about that 960.

 

Appreciate all the insights in the thread so far, this has been one of the best audio purchases I've made in my entire time in this place.

 

Big thumbs up to project86 and everyone else here.

Thanks so much.
