Nordost QB8


QB8 owners:

What configuration do you use when plugging your gear into the QB8?

I've got good results in the following order, starting from the end of the QB8 where the mains power cable plugs into the QB8:

1) Meridian MS600 streaming endpoint/DAC
2) empty
3) empty
4) Primary Earth Socket - Simaudio P8 pre-amp
5) Simaudio W8 amp
6) empty
7) empty
8) Simaudio 650D Transport/DAC

I have the QB4. I used to plug the amp into it but now it's straight into the wall. Your configuration seems to be good. You could use QV2's in an empty space or all of them, but I wonder if they really work especially at 350.00 each. Good luck.
Can you share the configuration ordering which your equipment is plugged into the QB4? Did you notice differences in the sound after moving your amp from the QB4 to the wall socket?
There is a big difference if you ground QB4 or QB8. I use Acoustic Revives ground conditioner rgc-24. I have also heard nice results using the grounding equipment from Entreq.

The difference is anything but subtle.

I also use QV2 but recommend that you be carful and use one at a time and listen as you use more of them.
Im using only two QV2. It can sound a bit too forward and bright otherwise .. a better option is to use QX2 or QX4 then the QV2 is not necessary.
I plug the preamp (power supply) to the primary earth and the TT, CD, and Tuner the rest of the way. The QB4 plugs into one socket and the Amp plugs into another. No difference plugging the Amp directly into the wall, it just frees up one socket on the QB4 so that the TT is not plugged into the wall. PC's are Nordost Blue Heaven LS. To be honest, the QB4 makes no difference in sound either. I have one because I got it for 200.00 and it looks to be close to new. Retail? Forget it, you're wasting your money. The PC's do seem to help some though.
I would second the advice about the QX4 or QX2. I can not think of any "tweak" that was more beneficial to my system, in terms of lowering the noise floor, increased dynamics. I had 2 and just sold one. Two are better than one, but not much. A single QX4 is a no brainer IMHO.

I feel the QV2 works well too, I havent compared the benefits of QV2 to QX4. If anyone has, I would be greatful for any observations
