Default CD mastering

Hi,

Does anybody have experience with or tips for equipment to be used to record (or master) CD's from analog sources?

Something like this http://www.fostexinternational.com/d...ts/cr500.shtml ?

Jan, in case you seek for highest quality, buy the equipment from Ed Meitner, EMM Labs.

Dag Jan,

I have been doing this, building my system over the years and still not where I want it to be.

After two low-end (~300 euro) PC-based ADC/DAC boxes (with mods) I am now going to buy the Tascam DV-RA1000 DVD recorder, if only to make recording from the big turntable in the living room easier.

I also looked into mid-end solid state recorders (Tascam, Fostex) but rejected them as their analogue input circuits and ADCs are built to a dreadful standard, only suitable for interviews and low-end movie stuff.

I have no illusions about the DV-RA1000 being better than mid-fi at the circuit level, but at least it is a big box with room for improvement, improvement that probably only requires ripping out most of the circuits feeding the ADC.

Just some observations:

Nearly all 1-chip ADCs have primitive half-band AA filters. Some have wide-band stop-band rejection not exceeding 70dB (!).

Record at 88.2kHz and do the downsampling after all processing in the DAW, preferrably using a downsampler of known high quality (I wrote my own routines in Matlab and now can trade aliasing versus impulse response).

If you have many dull LPs (I do), then use a really good analogue EQ between phonostage and ADC. Or modify a phonostage with a variable RIAA and use this to tweak treble.

Yeah, great stuff. Now, if I had another 20k euro laying around...
