I may have paid $200, I can't remember.  Last weekend I noticed that CompUSA is stocking a 24/96 manufactured by Creative.  It was well under $100, but I have no idea if it's a quality item.  The MIA is killer.  Also, I am definitely *not* one of those wackos who thinks he can hear a difference between different kinds of speaker cable and interconnect.  But the MIA has these giant 1/4" inch connectors that are absolutely beefy, and I definitely observed a noticeable improvement in sound quality when I swapped out the interconnects between my MIA and my amp.  This is the first time I've ever noticed an improvement in sound based on such a small change.

 

BTW, I didn't buy the new interconnects because I was trying to 'tweak' my system.  I actually bought them because the interconnects I was using with the MIA originally were grafted together, as it's hard to find a 1/4" to RCA cable.  I found these at Guitar Center, they're very nice.

Hi John,

I wonder where did you get Echo Mia for $150 from. The best price I
was able to find is $190 at "The Midi-Store".

Thanks,

Yura.

I'm glad to hear that MAD sounds good on your PC.  You stated that you were
closer to audio nirvana because you had bypassed the DACs in your SB Live.
While improving DACs is certainly a good thing, note that this doesn't
eliminate what is potentially the biggest problem with digital audio,
jitter.

A definition of jitter:
http://www.feurio.com/English/faq/faq_vocable_jitter.shtml

I have a box that re-clocks the digital signal, a Monarchy Audio Digital
Interface Processor.  This seems to restore the pace to music, and also
smooths out the treble.  I used to use it with my desktop PC, but found that
their was a greater improvement when I hooked it up to my laptop.  This is
primarily because my computer's audio colletions is mostly on my 60gig hard
drive, whereas I listen to MP3 CDs on my laptop almost exclusively.  And of
course, a hard drive would have *much* lower jitter than a CD-ROM, because
it's a much more stable mechanism.

One of the big problems with the SB Live is that it outputs a 16bit, 48khz
signal.  So it's doing some really weird resampling in real time, even with
44.1khz audio.  I used to use a SB Live, but I found that a cheap $40 Maxi
Sound Fortissimo sounded better when using the SPDIF output.  The Fortissimo
lasted about a year, but I replaced it four months ago with a Echo Mia,
which has 24/96 output.  For $150, the Echo Mia sounds stellar.  Even
without a outboard DAC or any kind of re-clocking or upsampling, it sounds
excellent.  In some respects, I find that MP3s played on the 24bit Echo Mia
actually sound superior to CDs played on my Harmon Kardon CD player.  Must
have something to do with the low jitter and the exceptional DACs in the
MIA.  Amplification is tubes.

Bottom line is that your MAD setup may sound good now, but you'd be amazed
how much better it CAN sound.

John

P.S.  If I can find a few minutes, I'm going to try upsampling a CD to 24/96
bit wavs using Cool Edit 2000, compress the wavs, then play the 24/96 MP3s
through the MIA.  That should really give my CDs a run for their money.
Another thought is to do something similar with the audio track of a DVD.

Mad + mpg321 just became my mp3 playback tool of choice based on output
quality alone.

FYI, my setup is a dual-boot RH7.1/Win98, with an SB Live and the optical
i/o daughtercard, feeding into a JVC RX-1028V A/V deck.  Under Linux that
optical S/PDIF output seems to be a nearly-transparent passthrough,
meaning it isn't mixed. I'm not sure if it's the card or ALSA doing the
sample rate corrections. Probably the card.

This has yielded what I believe is the cleanest possible pathway for
digital audio, because it's using the much higher quality DA's in the JVC
stereo unit. I believe that for a digital recording, the only point of
significant signal loss is the MP3 encoding and decoding. Thanks to MAD,
the vast majority of that is now the encoder.

Which leads me to the reason for posting: this implies that much of the
perceived fidelity loss of MP3's involves flaws in soundcard DA's getting
tickled by something in the MP3 algorithms.

I'm available for whatever testing anyone can come up with.
Keep up the good work!
