Bottom Line:   
Anyone reading this review is probably wondering why I even bother writing about 90's era technology in the 21st century . Although the GDA-600 certainly isn't a sophisticated product by today's standards I feel that it can still compete in the 21st Century.

Given a basic digital source this product represents amazing value if it's plugged into a proper amplifier which in this case is an NAD 218 powering a set of infinity SAT 450 speakers. Musical instruments are as clear as day and you can really hear the high frequency energy decay that mediocre systems are at a loss to replicate. The high frequency information on Hotel California sounds much more lifelike than my reference desktop system which uses JBL's LSR28P powered pro audio monitors controlled by an Integra DTC 9.4 preamplifier.

This product will turn any computer with a digital output into a high resolution audio platform.

Although the GDA-600 isn't setup with any large speakers or a subwoofers the detaisl on Operation Kingfish and UBISOFT's Ghost Recon Wildlands are amazing. In Wildlands you can clearly hear all the background noises in the various scenes and the music is both haunting and eerie. Whether it be the sounds of children playing in the village or bids overhead.

Likewise all the gunshots in Operation Kingfish are both lifelike and kinetic. Not only is it possible to hear every little of what's happening but the audio resolution immerses you in the film. You're not just watching Operation Kingfish you're experiencing it.

In both absolute and relative terms this is a product that be a part of any computer or digital audio platform. Note at this time moment in time the GDA-600 would probably retail for less than $200. With the right speakers and amps the GDA-600 can help create a more intense and immersive listening experience.

Bottom Line:   
I've been using this unit to improve the sound of my Yamaha 5-disc changer. The DAC in it isn't that bad to begin with, but the Adcom definitely makes some noticable improvements. Yet, with my 'mid-fi' system (Yamaha RX-596 Reciever, PSB 2B speakers), I wouldn't call it *dramatic* change. It does do some great things though:

First off, vocals have been brought to the forefront, and are not as drown out by accompanying instruments. The bass in sub-30Hz region is actually THERE for once, which seems to contribute to increasing the size of the soundstage. Percussion like snares seem to have longer decay and sharper attack. Some sounds even have a mild reverb added to them, which I never noticed before. A sonic veil seems to have been lifted from every recording.

I'm using it connected through a Toslink>AudioAlchemy DTI>Apogee WydeEye RCA>GDA-600.

In short, if I were without the DAC, I don't think I would pay 'full' price for a new one, considering the amount of improvements it gives (it's maybe held back by my other components?), but the improvement is definitely appreciated. I've grown to like the sound so much, I don't want to part with it.

I bought this at least 4 years ago and it served me well over the years. It was used with mainly a Sony XA3ES cd player.
But Ive since upgraded to an
Arcam Alpha 8SE cd player and the digital to analog converter in it sounds unbelievable! If youve got the time audition an Arcam cd player today.

Bottom Line:   
Not very sure for the year model.
This is a very good sounding DAC with detail high, punching bass and a lush soundstage. I am using it thru the balanced input (the other input availabe are : 1 Toslink and 2 RCAs).
This is not a 24/96 DAC and not HDCD capable.

I really like this DAC. It can't be beaten for the price.

This is a great sounding unit. The build quality is fantastic (especially compared with the MSB). I'm using both the TOSLink and the Coaxial. It has really improved the sound of my Sony CD/DVD player. It has also made my AudioTron actually sound GREAT!!

The highs are really wonderful, I can hear cymbals roll off beautifully (whether it's a symphony or Led Zeppelin).

If you can find one, grab it!!
