    How Many Inches?

    I'm currently using Heritage Linton's (8") and now some JBL 4312G (12"). Both equalized to the same curve in DIRAC (but slightly less low extension on the JBLs), the JBLs definitely have more slam, which is what I was after. I have a large room (>8 x 12m).

    NAD 50 Anniversary C 3050

    Yes you could do that. Probably better that the second amp has a fairly high input impedance so the pre-out isn't taxed wrt current too much. Preout output impedance is 439 ohms so it won't be an issue re any response variation or voltage drop. (i.e. even if both amps had a 10k input impedance...

    Measured effect of op-amp rolling on a phono equalizer input-shorted noise

    Noise maybe dependent on source impedance though, depending on the opamp. I did something similar on a similar phono amp (but two stage RIAA) . I used representative carts attached and measured the noise but calculated the S/N for representative input levels (5mV mm, 0.5mV mc) for two opamp...

    Woah. It must sound awful through those PA style horns.

    Turntable gift from the US to Australian Prime Minister

    What model VPI is the gift? Seems bespoke as it doesn't resemble any of the current product line.

    Turntable gift from the US to Australian Prime Minister

    He has the nickname "DJ Albo" but I have no idea whether he already has a turntable/s or not.

    Turntable gift from the US to Australian Prime Minister

    Anyone with any more detail? Likely a VPI of some sort? He has been known to do some dogy DJing, not sure a VPI would be any good for that! "President Biden will gift prime minster Albanese a custom signature turntable from a family-owned American audio manufacturer that includes a special...

    Introducing the Phono Cartridge Measurement Library

    I will try side 1. I can't remember which one I used for the older post.

    Introducing the Phono Cartridge Measurement Library

    I put my 2M Blue back on and set it up again. More top end lift but still not the same as the other measurements. Side 2 first track.

    NAD C3050 LE Measurements

    I'm enjoying using it and its flexibility means I use it in a number of ways: - LP with mm cart into phono input - LP with mc cart via a step-up transformer into phono input - LP via phono stage to line in, or to optical in via RME ADI-2 PRO ADC - Using the internal amp or the pre-out to my...

    Introducing the Phono Cartridge Measurement Library

    Similar to my (first cart attempt) measurement but with more droop after resonance on mine. As you said in your first measurement, sensitive to setup.

    Help: NAD C3050 paired with KEF R3's

    The initial firmware, at least for the LE version, had a max preamp gain of 0dB. This was subsequently changed to +12dB. It may be the same in the non LE version, despite the lack of BLUOS. Try a manual firmware update and see if it appears louder afterwards. The UcD amp modules cope with 2...

    Let's stop calling Class D amplifiers "efficient" when they are not.

    My NAD C3050LE integrated with all of its DSP and Hypex UcD modules, consumes: ~ 0.2W in deep standby ~ 2W in normal standby ~15W on but with speakers "off" ~ 23W on with speakers set to "A". The last two are interesting, as it seems it is doing something a bit more than operating a relay when...
