  The reason why a sophisticated DAC algorithm (as with the Hugo) can have such a major effect is the need for an anti-aliasing filter – because of the sampling rate of 44.1 kHz, thus the steep low-pass filter at 22 kHz at the latest. The filter is needed to prevent aliasing – intermodulation of frequencies higher than the Niquist frequency (½ the sampling rate) with the sampling frequency, leading to mirror images. Sine waves below the Nyquist frequency would look like this without the low-pass filter (mentally replace the triangle shapes with orthogonal steps). In fact there are some filterless DACs around, and all of them suffer from a ~3.5 dB drop-off at 20 kHz, a consequence of the visible signal modulation. In turn a typical anti-aliasing filter leads to the infamous «ringing», which may be audible.

This was pretty interesting.
 
So every ifi product is a no for me, as i really need the anti aliasing thing.
 
Is there any way for me to try to make something in computer, before sending the data to x5 DAC? like a plugin or something? so that i would get better music without buying anything for now?
 
are there cheaper DAC solutions than hugo that i can consider buying? or at least, could you point me to where to look for a cheaper solution? Usual DACs are not known for having a SQ to the hugo level, and cheaper DACs are even less probable to get near. Maybe meridian young, but it needs palmer, and the setup costs more than hugo, and it needs an amp, and it is not portable...
 
 
 
 
 

  On another note:  I don't recall if I posted this question on another X5 thread, but, there's a little iten of the 2.5 update allowing the use of X-FAT formatted cards.  Is there an advantage to this?  Will the data be stored more efficiantly on the card than with FAT32?
 

If you don't have files bigger than 4gb, it is better to keep fat32. ex-fat has advantages for very big files, as fat32 does not allow, but it has the drawback of not being so compatible. i mean, consider things this way, if you will need the card out of x5 and into another device, you will need to re-format.

 
I posted on the Hugo thread that I was listening to a radio drama ripped at 128kb/s mp3.  It seemed to smoothen out the rough edges of the playback that I noticed on other devices.  Not saying it's a miracle worker, but I noticed something positive in the listening.
Guess yull  just have to break down and buy Hugo, Skerry.  Who needs food anyway?  Should listen to Stan Freeburg on HiFi.

The thing is that as far as hugo goes, i am kind of not so willing to invest money in a product that costs so much and is not going to last me at least 10 years. i do mean this, i expect that at the price it will last me at least 10 years, which i vaguely remember that it was discussed, but i do not remember the life expectancy of hugo..

As far as that goes, it better last a good 10 years considering what I payed for it.  I'll not be forced into upgrade-itus unless Rob can bring out a DAC with 500,000 taps or so.
And thanks for the answer to my format question.

IFI also has different filters to choose from so I see no problem...

i tested idsd, it does not resolve the problems, it still has exactly the same problems as x5 has with the particular files, i tested all filters, with all possible settings, the problems are not solved. 
 
Basically, i do need a DAC that oversamples, and upsamples, to satisfy my need.
 
After doing a very quick research of what i can listen and is alavaible in my country, hugo is the cheapest solution, and the only portable one...
 
either that or i settle and accept the errors with x5.

You will hardly find a DAC that doesn't oversample (which is the same as upsample) these days, as part of a standard anti-aliasing filter.

What we've been saying for about 20 pages. Glad you've gone through the proccess though.

How about a USED Hugo?

 

[Dobrescu George]

I guess that this is the road i am going to take.  I hope to fiind one for a much cheaper price, as the price was the only drawback.
 
The good part is that i already have a perfect transport for a hugo, a fiio x5.
 
thanks a lot for all the help through all of these pages, and i am sorry if anyone had to read a discussion that was not interesting, i think that discovering music and understanding it is one of the best part of this hobby.

Anyone have an idea what this is?   Showed up when I skipped from one song to the next.

 

[freddy315]

Froze and had to do a long hold on the start button to reset.

I think you just entered The Matrix, bro

It's fixed now? Looks like the Analogue theme. Did you update to the 2.5 version?

 

[freddy315]

Yes, Analogue 2.5.

 

[Dobrescu George]

So maybe 2.5 did not like something about custom UIs and entered what seems to be debug mode..

Everybody finds half the thread not very interesting.
Depends on your personal point of view!
