Absolute ease of use through the navigational menu a well as dense clarity make the Tascam DV-RA1000 a fantastic choice as a mastering/mixdown recorder. The 44.1 kHz to 192 kHz in frequency is well within the range for any type of cd production from project studio to the full range super audio demands of the most extreme audiophile. I found that the integration of the 60 GB hard drive was an excellent compliment to my digital audio transfer from my laptop to disc as there is less room for error. I recently moved a pro-tools session to disc using the DV-RA1000 and finally got the quality that I had been looking for (for a long time) in a finished product. I would definitely consider the DV-RA1000 an excellent investment and the right mixdown burner for all engineers and clients.
