Yes Canare makes 75ohm RCA connectors but IMO, it's just a marketing scam. While a commodity RCA connector is hardly precision 75ohms, NTSC video and SPDIF are at a wavelength where that mismatch for...

Not exactly quiet or good WAF, but these guys do have a huge selection. And you can always remove fans and/or replace with quieter fans provided your temps stay in range.

Of course not. But sometimes all it takes is the threat. And then sometimes your bluff will be called. So use this as a last resort.

I don;t think the input cables could damage the amp either. Unless as suggested above they are some how causing ultrasonic oscillation.

I'm missing something here:

If the OP bought the unit at a price point and understanding it was a demo unit, then I can see CJ's point.

But if the OP bought a "new" preamp then the user...

Ok yes, the HDMI cable could couple 60hz trash back to the UMIK preamp through the ground wires.

The idea also goes against another sacred audiophile rule, that is to keep the signal path as straight wire as possible. And since CD players can drive most amps to full power these days, you really...

Well to spite the seemingly all digital USB path here, the mic still has an analog front end (preamp and AtoD converter), and this is powered from the computer's +5v USB power. It is not uncommon for...

The XLR and RCA jack should have exactly the same signal as far as any processing goes.

However in properly designed gear, the RCA output is a -10 to 0db and the XLR should be at +4db which is...
