Somewhere I think in XDA forums I have read that manufacturer of phone places restrictions in their hardware or software ie., OS not to support greater than certain size of memory ie., if manufacturer specifies it can support upto 64 GB and if I insert an 128 gb memory card it is not possible to read the contents from SD card using any of the tricks or hacks like formatting SD card to fat32 etc., is it true.

They have posted that if it is possible to read 128 GB memory card on a mobile which support only 64 GB then nobody is going to buy another new mobile which supports 128 GB memory card.

Vinyl / Re: >20kHz content found in vinyl?

If your vinyl setup sucks as bad as you say, its likely that there is something wrong with the setup or the LPs you have are in dreadful condition.
He said it sucks compared to digital.   I said something similar.    And, I'd say it sucks if you're bothered by noise.

You should not be hearing any differences in bandwidth for example, nor any distortion in any passages.
"Bandwidth" isn't the same as frequency response, and there are differences in frequency response with different cartridges.   Maybe "all high-end cartridges sound alike"...  I don't know...   But I'd be surprised if that were true...

Regardless, wouldn't you also want to subtract the noise of the phono section from your results? Otherwise the measurements might be skewed. Some phono sections are -85 db and some are -55db.
How in the heck do you listen to a record without the "phono section"?  It's generally not the weakest link but it's part of the problem.

And, I believe Arny said he removes the worst ticks & crackle, so that's giving an "unfair" advantage to the record, and making the results appear better than they really are.

I'd set the bar higher...  The average record is dreadful compared to digital, and records in dreadful condition are "unlistenable" to me...   I'd rather listen to silence than to a scratchy-old record.

Xiaomi Redmis surely do - Redmi 2 was also marketed with 32GB max - and yet it could handle 128GB without issues.

Recent Androids make a big deal out of restricting write access to SD card, but there should be no problems with reading the content.
Yes, all applications ought to behave normally.

Does all Android phones supports fat32 and ext4 filesystems atleast fat32 filesystem.

Suppose I have format my SD card to fat32 and I am able to access using es file explorer on my phone does all applications like music players etc., behave same as file explorer without any errors like file not found etc.,

In terms of power consumption, it's perhaps more sensible to pair Sansa player with op-amp swapped O2 (TLE2062EP) and enjoy high Vrms out combined with sub-200mW idle consumption, something Fiio and other DAPs have yet to show.

And just in case, you may want to check the ID3 tab to make sure it's not writing ID3 tags to the resulting files? I don't recall if this is still a possible problem with EAC, as I haven't used EAC to rip anything in years.

you can see in my screenshot above that "Use ID3 Tag" is UNchecked.

What do you use to rip now?

The tests were designed to be optimistic, as the maximum recorded level was -10 dB FS. This is about 1/3 of max amplitude.

Are you saying that at 0VU (because that would be full scale) on the LP, that distortion is 15-20%?? If so, the statement is clearly false. Not arguing with the math, but sumthin's wrong with this here picture! I'm thinking the 2% at -35db is not right... 2% at 0VU would be a lot closer...

Measuring the actual distortion is really problematic. You have to remove the distortion in the source and somehow negate the distortion of the pickup and EQ (please correct me if we are talking apples and oranges). But if I recall correctly, 2-3% is an accepted norm, but with proper equipment I think you can do better than that (I use a Triplanar, which might be the most adjustable arm made).

The key to LP longevity, in this case based entirely on my own experience, is to insure that the cartridge is in fact tracking properly. This is the tricky bit as cartridges and arms are not always compatible. But if you get it right, there will be no hint of distortion regardless of the track in question. At that point you get the minimum wear of the surface as well.

I find that the biggest enemy of the LP is improper storage and a failure to handle the media properly.

How about one of their cheaper (not the loudest) product?

Battery life for smartphones can be long or short, depends on user behaviour, doing nothing but play music will have longer battery life for sure.

I like fiio but I don't think the current batch of audiophile players is very good. For example that device gives you about 7db more volume than an average Qualcomm phone in exchange for 128k mp3 playback time comparable to the screen on time of some phones. In terms of power consumption it is easily 10x worse than a decade old mp3 player.  For some people this is fine, but I don't really understand why battery is do poor.

The xudoo x3 is fairly similar (based on a similar reference board as fiio uses I believe).

IME my FIIO  X1 gen 1 equals or outplays MP3s on my Sansa Clip and my Fuse.  Its measured performance is more than good enough, and generally better than the older Sansa products. The Courier font menus are legible, but not all that pretty.

From the spec sheet, it looks like the X2 is still decent.

Every Android phone with a microsd card slot ever made will support up to the maximum size allowed by the standard, which is 2TB.

 No the statement is false because I have inserted a 64 GB micro SD card into the memory card slot of a phone which doesn't support 64 GB external memory but supports 32 GB and I was unable to access the content present in 64 GB memory card.

The above happened a number of times for different phones.

Interesting fact is that when I connect 64 GB memory card through USB otg to an Android phone which doesn't support 64 GB external memory I am unable to access the content.

This report describes a potential false negative indication.

A SD card can be too big or have the wrong format, and from the phone's viewpoint all you will see is nothing.

The "one size fits all"  solution is FAT32.

But Windows won't let you format everything FAT32, even though the device can probably support it.  Once formatted, Windows can see it, too.

To make large FAT32 volumes, there are freeware programs for Windows that will bypass the artificial restrictions that MS put in to force you into EX32 or NTFS. 

You see the patents have run out on FAT32, but are still capable of generating income for NTFS and EX32.
