HE-500, LCD2, D5000, DT770, SR80, on a speaker amp (Emotiva mini-X A-100) Project - Page 76

Brio-R was too aggressive on the volume knob for HE-6. Wouldn't use it for HE-500 myself.

Edit: ...according to a local head-fier.

Okay... As long as 9 o'clock matches my normal listening level I'm okay with it. Else I could get attenuators from my DAC to a potential amp. Might try it in a shop.

Sorry, what is amp having a "common ground"? I may use a HE 6 adaptor or 4 speaker wires connected to the amp and terminated with XLR. Thanks.

Common ground is when both channels are connected to the same ground circuit. Some dial mono (internally bridged) amps have each channel connected to a different ground circuit. If you put a multimeter on the outputs the meter should show 0 or close to 0 resistance across the outputs.

Thanks. Would it affect my situation if I use the emotiva mini amp with the HE6 and the adapter (4wires to amp and the other side XLR terminated?). What if I use HE6 adaptor box or 4 wires to amp with 1/4" headphone jack adaptor? Thanks.

I think I need a picture here, you have me confused a little.

There is a little more info here.

Here is what Chris Maritns has to say.

Hi donunus,

The HE-6 uses a two-piece cable assembly where there is a "Y-cable" that connects to the headphone earpieces and that terminates (at the "Y-junction") in an XLR connector. From there, you can plug in a variety of amp cables to connect to whatever amplifier you use.

The HE-6 ships with two amp cables, one for use with traditional headphone amps, and the other for use with full-size integrated amplifiers or power amps.

The traditional headphone amp connector cable provides a 1/4-inch phone jack on one end and an XLR connector on the other (which, of course, clicks into the provided Y-cable).

Alternatively, the power amp cable provides two pairs of color coded banana jack connectors on one end and an XLR connector on the other. Thus, you simply plug the banana jack connectors into the speaker taps of your full-size amp, cautiously turn up the volume, and enjoy.

To see a photo of the HE-6's standard cable sets, check out page 2 of the posted review. The power amp cable is pictured on the lower left of the image frame.

Best,

Chris Martens

Thank you C Martens. I will carefully read the information you directed me to and see if it makes sense to me.

On another matter - is there any risk of damage to the Grace Design M903 if I were to use the HE6 with it? My emotiva mini amp isn't here yet so I thought I would try it out with the M903. Thanks.

No, the warning is only for people using the 1/4 TRS (single-ended) to 4 banana/spade. If you tie the ground of an amp that doesn't share ground, let's just say bad things will happen.

No risk.
