    New Record Cards!

    Have introduced our NextGen outboard chassis version for the Nagra T-audio with the DIN high-inductance (880mH) amorphous heads, with outstanding results -I expect to have a user review as well as comparison against the NextGen equipped Studer A80 RC on WBF soon. So we can today offer a...

    New Repro cards!

    I have a stellamaster as well and I agree with you. All discrete transistor amplifier modules-making my point once again versus opamp designs (but with class AB output stage that can be simply upgraded to class A by adding a 8-10mA current sink pull down (2n5459 Idss 8-10 mA ) on the SOC outputs...

    New Repro cards!

    Jonathan: I have not heard the Sony APR 5002/3 series in conditions familiar enough to me that I could make a fair assessment of its sound, or direct comparison on the same source material against different decks; I also have NOT had the opportunity to make any technical measurements of the...

    New Repro cards!

    I also agree that on careful review of its published audio schematics for record and repro, I would expect the ATR in stock form to offer the best audio quality of any of the stock professional machines, including the various models from Studer, AEG Telefunken, Nagra, and the others I have...

    New Record Cards!

    Actually I am looking at an M15A for purchase tomorrow which I will setup for use with my NextGen outboard record/repro electronics. So I expect to perform the measurements needed to have finalized head loading, wavelength model, and the rest of the complete calibration data needed to duplicate...

    New Record Cards!

    Of course you need to grab the repro head outputs directly: typically this is done one of two ways: direct connection to the head outputs in the headblock or at the headblock connector itself; or at the audio card cage repro head connections (often removing the repro cards and using a “bypass”...

    New Record Cards!

    1. the only modification required is to bring out the repro head outputs (2 channels) using an appropriate high-quality shielded twisted pair cable per channel; generally this cable should be kept as short as practical to minimize hum pickup; we can assist with specific cable recommendations...

    New Record Cards!

    Interfacing low-inductance (I.e. low output) repro heads pose no problem for our outboards, and actually simplifies very much the shielded twisted pair output cabling from the repro head to the outboard electronics as cable capacitive is less of a concern; we have ample preamp head gain...

    New Record Cards!

    We have very successfully interfaced our NextGen outboard tape electronics with the Studer A80VU, Ampex ATR-102, and the Nagra T-Audio (including the high inductance 660-880mH repro head) at this time. I myself have always thought very highly of the Telefunken M12 and M15 engineering, and I see...

    AK (hot rodded) Ampex ATR-102's w/MR-70 Preamps replaces my Studers.

    Mike: Just to let you know, going from the Ampex ATR-102 432 Khz Bias down to 150Khz bias will increase tape Bias noise by at least 2-3 dB (due to Bias lower sidelobe and anhysteretic magnetic tape oxide behavior) which means at least 2-3 dB reduction in A-wtd SNR. This applies to recording. I...

    AK (hot rodded) Ampex ATR-102's w/MR-70 Preamps replaces my Studers.

    I wasn't trying to "plug" our NextGen A80R/C repro cards in this forum; I will gladly leave that to user comments from our customers. My interest is strictly as audiophile and engineer (I have 10 US Patents in Wireless and Ultra-Wideband Data Acquisition), and advancing the State of the Art in...

    AK (hot rodded) Ampex ATR-102's w/MR-70 Preamps replaces my Studers.

    You are absolutely right in questioning specs that bear little resemblance to what is heard or can be heard, or come at the expense of other critical characteristics not mentioned; too often specs have been used as a cheep way to hawk equipment to unsuspecting buyers, and today it is especially...

    AK (hot rodded) Ampex ATR-102's w/MR-70 Preamps replaces my Studers.

    Mike: Sorry to burst your bubble, but magnitude frequency response - in isolation - that is, without phase- or Group Delay- measurements vs frequency, or better yet full time domain impulse response and coherence function measurements along with the usual THD/IM distortion and SNR - is NOT...
