The Project II card has a DSP as well. It's for driving the I/O, making that sound go into your computer with as low latency as possible

I see differences on AMIIIvs001
001 has a motorola XC56301PW80, an ALTERA FLEX (DSP FPGA I think), and a own digidesign chip. Some Esi cristal CS8403A'CS and CS8414

AMIII can run old waves plugins (motorola 56k coded) that 001 could not. Also Arboreturn runs in AMIII and not in 001.
 I think AMIII is the first "LE" system. It is almost TDM without TDM power but TDM chips... And the first one to not need 88x, control24 or ADAT bridge.
In 1999 Digi001 changed the music industry (again).

Oh My God! The DIGI 001 pci card form above has been modded! The ecliptek ECX 1427 for the component on Y2 is not a clone of Y1 ecliptek ECX 1548. I  guess is for 44.1 kHz clock...

I bet those older 16bit 888s don't sound too bad, probably just about the same as those 888|24s. Or am I mistaken?

they sound totally different, and maybe even better, especially when you clock them from a big ben.

but i think i dont need to explain you why 16 bit recording also has great disadvantages. you might have analog limiters for a bass and ffor micropühones, but do you have a total of 24 channels analog limiters? and if yes, how much noise do they produce?

I LOVE how AMIII sounds. I like how Digi 001 converters sound 24 bits bla bla bla. But AMIII at 18 bits sounds more musical to me...It is something really hard to explain, but really fast to listen and notice...
I run the "Be There" from PT5, and "Meant to Be" from TDM PT6 on both sound cards in OS9 and prefer AMIII sound. Digi001 converters sound "cheaper" and lots of users take advantage of rosetas in LE systems. Also lots of AMIII users bought RME ADI 2

one thing to note about RME is they are consistant..they dont pull their products from their product line like tascam and all these other fly by night companies that keep trying to win the audio market lottery by inventing the next big product... changing their product line every 3 months.. and the RME ADI-2 is still for sale in 2015!!! http://www.sweetwater.com/store/detail/ADI2
i saw some articles just now comparing the ADI-2 to a lynx pci product the L22 http://www.ebay.com/itm/Lynx-L22-Two-Analog-I-O-192KHz-2-Digital-I-O-96KHz-Card-/371048972093

what other high quality 2 channel DA-AD converters are there?

http://www.soundonsound.com/sos/jan09/articles/daconverters.htm
this article mentions the apogee mini-dac .. when the mini-dac came out much earlier.. like in 2002 or 2003 i think!!
so apogee is another company that sticks with its products?
this video shows it has a firewire port too.. so i think u can power it by firewire to connect it to a g4
[youtube]http://www.youtube.com/watch?v=dRzE649kAtk[/youtube]
but unlike the the RME ADI-2 it doesnt go both ways.. (A->D, D->A)
so i guess i should have been talking about the rosetta by apogee
http://www.sweetwater.com/store/detail/Rosetta200/

but wait
http://www.soundonsound.com/sos/jun03/articles/apogeeminime.asp
this is the thing i was thinking of.... it looks similar but its a different product
i must have got them two confused.
[youtube]http://www.youtube.com/watch?v=Rstm1h3S-1c[/youtube]

also just saw this option from cambridge audio
http://www.sweetwater.com/store/detail/DacMagicPBk
never heard of this one but its only digital to analog aswell similar to the mini-dac

this idea of using higher quality more modern conversion equipment connected to legacy/retro pro tools hardware
it intrigues me, but by doing so, wouldnt you be bypassing the "magic" quirkyness of the old analog filters that defined the type of sound from that hardware?? like u said u preferred the sound of the AMIII to the DIGI001.... u are really talking about the analog converters right.. using both the digi 001 + amIII with digital converters via ADAT + S/PDIF would basically eliminate any of the known character from both of these pt interfaces, right?

Yeah, but the Jitter is there https://en.wikipedia.org/wiki/Jitter

Best converters/price today... Prismsound http://www.prismsound.com/

I compared the outputs of 192 I/O vs Focusrite LS56 vs Presonus Central Station.

To my ears, the LS56 was the better, but Presonus was close. To my ears, the 192 sounded "worst"

But to my master engineer friend, the better was the presonus, them the 192 and last the LS56.

Also tested Motu 828 mk2 vs FS LS56. In a light test, you couldn't notice what was connected.

I didn't see the 1622 mentioned yet?

Mix core cards act the same as Mix farms when used in the second slot.

I also did not see any mention of the midi options. I personal am using the Opcode Studio 4. I got it for $1 on ebay and it is like new. to make this work you will need to have the modem din cable input on your G4, and make sure if you buy one to get the cable otherwise you will have to build your own. I have the schematic for this.

I am using an Apogee Mini Me preamp as my main Mic Line pre connected via digital coax to my 882. This thing rocks. I also use it via USB with my mac book totally plug and play awesome, great built in head phone monitoring, built in comp limiter, and it will run on batterys for field use. 

Speaking of 882's dont buy the old version with the external power supply they die and then you cant get a replacement, get the newer version with the internal supply.

hey there RTIInstaller
midi options are discussed in other threads at long lengths if u look on the board index (be sure to check teh "stickied" threads at the top? in the gear section http://macos9lives.com/smforum/index.php?board=42.0)

Just a quick interjection, there are other factors that will "color" a sound that have nothing to do with the converters.   The op-amp (Operational Amps) are probably the main culprit in the input stage that will lead to a noticeable alteration from the source (perceived as a EQ differences and variations in the harmonics of the original source.

The better the interface, the better the op amps.  "Harsh" sound is usually perceived from a 'low quality" input stage that has already thinned out some frequency ranges (before you even get to the A/D stage).

Another factor, a common misconception, is the someone will say that the interface "colors" the sound and that it is "muddier" when in fact this is just a shitty internal clock (as discussed before in other threads) and is not a colorization at all... it is merely a high jitter ratio on the captured samples and thus the sound is perceived as "thin" or "colored" or "muddy" due to variations in the sample clock crystal (NOT the A/D at all)

Let's also remember, the D/A also has Op amps (separate from the input stage) and if you are monitoring via your interface, some colorization will take place at the output stage.  A test I use on other peoples tracks, is to listen to the tracks back via SPDIF (lightpipe) thru a few interfaces to get a better idea of the sound of the actual tracks.  By doing this, you can at least go digital directly to a few different monitor sources, without added coloring.

I would say that the 'warmth' I heard in old Apogee interfaces were a combination of great Op amps, good converters and a solid external clock.  So when I think back now, the sound wasn't "colored" to sound warmer, it just sounded better because the smearing, and muddiness was not present... so in fact, it was just that it sounded closer to the source, not that it was colored.

I have an audio alchemy series 2 DAC which is a pretty darn good sounding DAC I connected it to my system via dig coax, I A/B ed the heck out of my system, honestly the difference was very slight versus using the stock analog outputs. I don't even use the DAC now as its just not great enough of an improvement to justify using it.
