If I buy dueling, is it still 10 ohm?

 
Yes, you can buy them from Parts ConneXion. They are suppose to be the best resistors for
crossover networks, very expensive.

Here's some discussion about them from agon.

I use 10ohm resistors in parallel but not the 25ohms. In this amp, I soldered the resistors between the speaker terminals inside the amp. The 10ohm resistors provide some protection too since it absorbs most of the power.
that's mean need to put the resistor inside the amp? Thank again for your hep.

If possible show layout how to put the resistor, thank.

I have to say I feel the bass on the Master-6 is stunning. Absolutely not laid back, but maybe that's the difference between the NFB-7 and Ref 7 dacs.

 
Could be, a freind of mine tried the Ref 7.1 (coming from W4S DAC2) and said he found the bass laid back.

Yes I don't think the Sabre32 chip does laid back bass

It's a good thing that you couldn't hear a difference.  That's even more of a reason to leave them on.

I know where you're coming from, but I use this amp to power my speakers too, so it was a pain to swap the resistors in and out.

Rather than solder the resistors inside, why not just get some stackable banana plugs like this: http://www.amazon.com/Ocelot-Banana-Plugs-Plated-Connectors/dp/B003BKW2K2
stick the resistors between one pair, then daisychain off that? Then to switch back to speakers, just pop out the resistor set.

In my case that amp is a small tube amp that I only use for my HE-6. I can snip them off anytime. I don't like banana plugs, they can't be tighten like spades.

If I could find a cost effective pair in copper I would.

The RSA Intruder portable balanced DAC/amp was very nice with the HE-6 at RMAF, and a step up in bass weight and impact over my stock RSA SR-71b.  I was surprised, because the HE-6 can sound thinner and brighter when underpowered, and they do exhibit some of those traits with the SR-71b, but not with the Intruder (nor with EF6, Emotiva BPA-1, Marantz 2240, etc).
