RIAA curve in Pure Vinyl

205.173.24.4

Hi -- I have just been experimenting recording vinyl with the demo of this software. I have some experience doing vinyl rips with my old windows based system, using Ableton software, which I thought was pretty good. I have a Scott integrated amp rebuilt by Mapleshade, and I take the tape output and feed a Fireface 400 for the A-D part (something I guess the original builders of the amp in the 1960s never envisioned).

Rob Robinson at PV suggested sending the turntable output into the mic inputs on the Fireface as a preamp, to enable RIAA correction in the Pure Vinyl software -- he actually sells adapters that allow the proper cartridge loading in front of the A-D.

Has anybody had any experience setting up their system in this fashion? Im wondering how it might sound vs. the RIAA curve/preamp built into the Scott. Thanks. -- David

I'm doing that with the mic inputs on my Fireface 400 and I'm extremely happy with the entire setup.

  Bwb -- Thanks.My first attempt at it produced music that was bright and thin. Rob had cautioned that without the right cartridge loading the treble would be tipped up, but this seemed not good -- especially compared to the analog output from the Scott preamp. Do you use the adapters or cables he supplies for that purpose? Any other tips on making the connection with the Firface? Thanks. -- David

    I didn't use his adapters. I modified the inputs to the RME to accomplish the same thing.
    
    I am not surprised it would sound different than the Scott but are you sure it is now bright and thin or the Scott is dull and bloated. If you are used to the latter then it will not sound right to you. Perhaps a combination of incorrect loading and the sound of the Scott.
    
    What cartridge are you using?
    
    Is the input gain set properly.

      Thanks. I'll have another chance to tinker with the system this weekend and check the gain, etc. I have the Soundsmith entry level cartridge. -- David

David,

I've no direct experience but have a look in the Stereophile archives as I'm sure Mikey Fremer tried using Channel-D's own flat pre-amp with digital RIAA equalization and was very positive about the results.

I heard Channel-Ds presentation at the recent Newport Beach show and was suprised that to find out that the digital RIAA can be used in real time as well as for archiving. They used a Lynx Hilo A/D&D/A box to do this.
