First, GFCI are generally not well thought of for audio. Period.

Second, hospital grade outlets aren't up to audio snuff either, as they are really designed to resist chemical cleaners mostly.

If you're looking for good sonics on a dime, try the P&S outlets and look for the recommendations here.

If you're willing to spend a bit, try the Furutechs, and beyond that are the Oyaides.

All up to your ears and your budget, but GFCI and hospital grade are not what you need to look at at all!!!

Balanced power requires GFCI protection. The 2Q has all other outlets wired downstream of the GFCI, so it protects all outlets.

I plan on using Furutechs for the other 4 duplexes, but I do need a GFCI. :)

  I guess I just thought I knew what a GFCI receptacle looked like - my Furman IT-Reference 20i has 8 balanced power outlets and 4 non-balanced amp outlets, all of which use standard orange Hubbell CR5352IG (I think). These definitely are not GFCI receptacles and I don't see a GFCI anything anywhere. I only see a run-of-the-mill circuit breaker (push button) on the back. What am I missing?

    I would say the push button is a reset for overload current protection as well as GFCI protection.

    - I should add..... - jea48 07:50:59 09/22/08 (0)
      If the push button is also for GFCI protection you should be able to push the button to test if the GFCI is working properly.
      GFCI should be tested to make sure they are operating properly.
      
      Best way to test is with one of these. (Open in New Window)

    I don't see a GFCI either. That's odd. Perhaps Furman is using some other method to detect ground leaks?

      Usually by the power inlet of equipment you will see a UL or UL/CSA label.
      
      Do you see the label anywhere on the unit?
      
      If not, good chance, the unit is not UL or CSA tested for safety in the US or Canada.

      It does say "GFCI Protected" on the back panel (see your picture) - don't know how...

        I saw that right after I posted. :)
        
        I just checked out the manual:
        
        Though virtually all domestically produced electronic equipment is designed to detect electrical shorts and other potentially
        dangerous equipment problems in the Line lead referenced to its Neutral, this is inadequate when power is symmetrical. With
        the IT-Reference 20i, both neutral and positive legs contain 60 VAC relative to their Ground tab. This is not a problem or safety
        hazard, unless there is a defect in either the IT-Reference 20i�s transformer, or the power supply of a connected component. In
        this instance, we need to assure that safety is always maintained. The solution is our GFCI (ground fault circuit interrupter).
        
        The Furman GFCI detects any imbalance in the current flowing in the two hot legs. The missing current is presumed to be
        flowing through the ground conductor (the round pin on an AC outlet). Ground current often indicates a dangerous partial
        or full short circuit. If an imbalance is detected, the GFCI will trip the main circuit breaker/power switch. To restore operation,
        correct the fault and turn the unit on again. 5 mA of current is enough to cause the GFCI to trip; to troubleshoot this type
        of problem, start with nothing connected to the IT-Reference 20i. Then, add each piece of equipment until the GFCI trips.
        Contact the manufacturer of the suspect unit for possible solutions.
        
        Apparently, a button on the front tests the GFCI. Furman might've designed their own GFCI, but I'm not sure. Can you open the top and take a look inside?

        To remove the "top cover", I will have to unplug everything and move the unit - all 85 lbs of it - to a table as the cover is one piece for the top and the sides and is removed by sliding it off the back of the unit. I will try it as soon as I can.
