Computer audio questions

March 16, 2010

To Colin Smith,

I read your first "The Digital Domain" and I admired your passion for great sound. If you have free time I would like to ask you for some advice.

I have a Pioneer DJM 400 mixer, which I connect with my stereo amplifier and my personal computer. I had an M-Audio 24/96 soundcard and now have ESI Juli@ and would like to improve the sound, but I have a dilemma. Should I buy a better soundcard or buy a DAC? Also, is MP3 at 320kbps good enough or is FLAC a better idea? I am interested only in sound reproduction, not in recording or MIDI. I am not a musician, just an audiophile. Thanks for your time!

The trouble with internal computer soundcards is that they are subjected to the harsh electromagnetic environment inside a computer and they share the same power supply as the rest of the PC. These factors can affect sound quality. A problem I'm personally experiencing with my HT Omega Striker 7.1 is that the company doesn't have Windows 7 drivers capable of 24/96 data transfer, a fact that appears to be true of all cards based on the CMI8770 chipset. This doesn't affect USB D/A converters like the Simaudio 300D I have now, which doesn’t need drivers and is plug’n’play.

As for the quality of music file formats, I think you'll find that FLAC is vastly superior to MP3. The MP3 file format cuts out a lot of music data to make small files and is like a person with no head and no feet: they might look like a person, but they don't work too well. On the other hand, FLAC files are lossless and so you get smaller file sizes without compromising performance. Try the free ripping program Exact Audio Copy and the free player foobar2000 to hear how good PC-based audio can sound. . . . Colin Smith


Gallo speaker impressions

March 5, 2010

To Doug Schneider,

As much as I wanted to attend CES this year, I was unable to. I would have gone just to hear the Gallo Reference 3.5 speakers. I heard the 3.1s for a short time and was knocked out by them, only wanting a bit more bass impact. Can you tell me how the bass sounded with the new 3.5s? I am thinking of purchasing these speakers, but am trying to gain as much information on them as I can.

Best regards,

Bill Demars

Designer Anthony Gallo drove these speakers hard for us during our CES demo and I was blown away by the 3.5’s bass depth and impact. I never expected it from such a compact speaker design. I only heard the 3.1 casually, never critically, so I have no idea how they’d compare. But the 3.5 certainly impressed me. . . . Doug Schneider
