Cheap - effective A/D converters?


Recently acquired a EAD DSP-9000/III . Very satisfied with the sound of this unit - but it has left me with a connection quandry. The EAD is a all digital till the output.
I have developed a short term kludge to feed analog signals into the digi inputs of the EAD.I put my Marantz Dr-700 CD burner into record analog inputs - pause it ( you have to put a CD-audio disc in for this to work) and presto-gizmo I've got 44.1 digital coming out of the marantz and into the EAD. A niles AXP-1 used backwards allows me to manually switch between my TV and Tandberg 3001A tuner.

Rest of system consists of Paradym Studio 20's ,Hafler DH-120, dirtball Technics CD changer run into the EAD via TOslink ,Garden variety phonix gold interconnects and Kimber 4TC speaker wires and some video stuff that isn't important to me .

While I am inordinatly proud of my kluge with the Marantz - I've been looking for a more straightforward A/D converter.
In the semi-pro areana - I've looked at the M-Audio Flying Cow A/D -D/A converter. These run around $250.00 for a stereo unit . Anyone got any experience with these ?
Any suggestions for other cheap alternatives ?

Eventually when I get my ADC B-100 pre-amp and LP-12 up again i may be interested in higher quality A/D conversion - but for now the bucks are important and the analog sources are not of suffecient quality to merit any great expenditures.
Appreciate the help.

M_Audio SuperDac is inexpensive and has an excellent reputation. Details in user group at

M-Audio is better with an OADE mod. The Flying Cow is alright. I would suggest you visit www.taperssection.com I believe some one has an Apogee AD 1000, DA 1000 and it's power supply for sale for $450. Also, look at MSB, I think they have a decent AD for around $450, too. Of course Apogee's Minime and Grace Design's Lunatec are about the best but the cost much more.
Sorry

Couple of months ago I replaced the OE wallwart with a DIY power supply unit. That brought about a major leap in performance.
