Going from memory the ADI's I've worked on were the 48 k version.
The converters were AKM, but not their best stuff.

AFAIK:

ADI-8Pro uses AK5392 (116 dB, 48k)
ADI-8DS uses AK5393 (117 dB, 96k)
ADI-8AE uses AK5383 (110 dB, 96k)


AK5393 was "their best stuff" several years back when the ADI-8DS was
designed.



the Alesis HD24XR 96k. It uses the same A/D's as the $13k Radar
96, and I like the AKM 5393 D/A converters in there better than the
rough sounding Analog Devices AD1855 dac's in the Radar. $2500 for 48
channels of 96k converters, oh, and they throw in a hard drive
recorder in for free!

Have you modded one yet?

The converters were AKM, but not their best stuff. The M-DAC's used
for gain adjustment cloud the audio as well. I know the Myteks as I
did some analog design for Michal, they are top notch, but expensive.
If I were in the market for any of these, I would rent them all and
line them up. If you're looking for good quality converters in mass, I
like the Alesis HD24XR 96k. It uses the same A/D's as the $13k Radar
96, and I like the AKM 5393 D/A converters in there better than the

Jim,

Simply using the AK5394A converter chip won't cut it. A significant
impact on the sound quality comes from the clock as well as the
quality of the surrounding analog components which can be quite pricy.
Also, RADAR is designed to double as an external converter with two
simultaneous 24 channel digital I/O and digital pass through mode.
Many of our customers buy RADAR for its sound quality and only used it
as an external converter for Pro Tools or other DAWs.

That RME uses run of the mill 24 bit AKM stuff, ok, but not steller.
The Lucid 2 channel AD 9624 uses the Crystal CS5396, still the best
sounding A/D chip that includes very cool noise shaping options. This
is the top-o-line converter chip used by Apogee, Mytek, etc. I also
mod the lucid as well as the RME, the lucid offers higher performance,
best for critical acoustic work.

Yes, as I own one. It has the 33079 opamps replaced with the best 14
pin sm quad opamp, the BurrBrown OPA4134. The coupling caps are
replaced, high voltage film caps are installed in the switching psu, a
low noise fan and filter foam was installed.
I ran it up against a stock Radar 96 recording a Drum Workshop kit
with modified AKG mics, Kimber silver wire and Audio Upgrades High
Speed Mic Preamps. The Radar sounds fine, but the Alesis had better
top end detail and microharmonics, and the low end killed the radar
for depth.
Enjoying the $10,500 I saved.... Used it to buy Nuendo 2.1 so I
won't miss anything about the Radar's editing capabilities.

TTBOMK, my ADI-8 DS was the first RME mod Jim did. I had him modify two
channels and then send it back for listening--the difference in sound on
HF transients was quite obvious to my ears, so I sent it back to have
the rest of the channels done.

Thanks...

I am wondering if the Alesis AI-3 has similar quality converters?
This would be nice because you don't have to pay for a hard disk
recorder.

Fill in the blanks.

1. What year did the AI-3 come out? _______________
Hint - it was before 2000

2. What year did the HD24XR come out? _____________
Hint - it was after 2000

Any more questions?

Can the HD24 operate as a converter set? That is, can you route the
analog inputs to the digital outputs and the digital inputs to the
analog outputs at the same time? This would allow us to use it as a
front end for, say, Nuendo.

Is the only difference between the normal HD24 and the HD24XR the
addition of the EC-2 I/O upgrade?

I greatly enjoyed my time with the RADAR24. The RME ADI-8 DS which I now
have may also be used as an external clock master or slave.
