I have just received my ADI-2 Pro FS R BE and I am finding the manual overwhelming.
I would like to be able to set it up to digitize my LP collection at DSD256 but I am struggling to be able to select it.
I can't seem too change the PCM sample rate above 192kHz or the DSD rate above DSD64.
I have tried changing the mode between AD/DA and USB but no joy.
Could anyone give me a simple step-by-step guide to set it up for DSD256 capture?
The setting is at:
• I/O / Analog Input / Settings / AD Conversion: DSD
Your recording software might need to be active in DSD mode to actually make the setting happen.
USB Mode should be the way to go.
I have to admit, I‘m not 100% familiar with it, as I avoid DSD like hell.
It‘s an end user format that was meant to be distribute fully edited and processed audio on discs.
It’s simply a-pain-in-the-a##, with all it’s limits and complications (outside a straight SACD disc).
It locks out the slightest editing, not even native volume change is possible, and by no means click removal or anything else can be done.
I‘m doing professional recording studio vinyl transfer, intended to be used for commercial re-release of recordings where the original master tapes are lost.
After checking and evaluating multiple formats (even with my clients), PCM 96 kHz / 24 bit turned out to be the way to go.
Anything higher did not result in the slightest sound improvement.
Most important for good transfer is, in order of importance:
• Cleaning of one side only of the disc, a record-washer is mandatory, any will do!
• Wet play of the disc immediately after washing, when any residue is still soaked and softened from the washing.
I mean real wet with a thin film of distilled water / isopropanol mix on on the whole disk.
Only the needle tip may dive into the water, the needle carrier and of course the pickup itself may absolutely not.
This way ALL dirt is removed, and static electricity discharge that causes clicks is prohibited.
Needle tracking force can be increased to the upper limit of the pickup’s specs, bettering the tracking.
Needle and disc wear will be close to zero in wet play.
• The used pickup, it‘s needle shape (Micro-Ridge is best), and the wear state of the needle.
Micro-Ridge has the best tracking AND doesn’t wear out, as the needle has a very fine contact-zone with a wear-margin that can wear without changing audio quality.
This means full audio spectrum even at the critical, denser and harder-to-track inner grooves.
• Pickup alignment, most important the tilting of the pickup seen from the front.
The slightest mis-align causes asymmetrical crosstalk, which is clearly audible, as crosstalk is best at -35 dB anyway on vinyl.
Next important, pickup mounting position along the length of the tonearm, as it defines the horizontal tracking error optimization.
Tonearm, seen from the side, should be parallel to the disc surface, but that’s not too critical in my experience.
Of course, tracking force should be controlled, but that’s almost a banality.
• Tonearm and disc player: I had a lot of (quality) turntables in my life, and never had the feel there was a big difference in audio reproduction, even compared to the original master tapes (I’m producing music now for decades in my own studio).
I like my Sony PSX 800 Biotracer Tangential with Dynavector DV-17D2, but my Thorens gives comparable results, and even my little Sony PS-FL-77 / Ortofon OMP-40 is great for occasional listing.
• Only after that I’d worry about the recording format, of course a good AD-conversion is needed to preserve the analog disc feel.
44.1 kHz / 16 bit (CD-format) is NOT sufficient.
If you want to be way clear of all limits, PCM 192 kHz / 24 bit is 100% transparent (meaning true to the source) by a good margin.
When using my ADI-2/4 Pro SE as a preamp just for direct listening, that’s the sample rate I choose.
It does not limit any of ADI-2’s features, like SRs above partly do, and which DSD almost completely does.
