Anyone use an AVR-520 with GR A/V-1+? (1 Viewer)

[Bob Friend]

I'm considering building a pair of A/V-1+ from GR Research. Has anyone used these with the HK AVR-520? I'm worried that the receiver can't handle the 4 Ohm load.

HKs are stable into a 4 ohm load...at least that what the manual for my 320 says

Bob,

I would not worry too much unless you want to listen Loud. I had a Yamaha 995 running some 4 ohm Kefs (before I switched to GR Research AV-1s), and never had a problem. So you should be ok.

Great speaker choice, I just love my A/V-1s and supposedly the 1+s are even better.

Thanks for the replies. This is why I was concerned (from HK's website)

However, there are some manufacturers' speakers that have a minimum impedance well below the 4 and 6 ohm nominal impedance. In this situation, the receiver will protect itself by going into standby mode.

The A/V1+ has a minimal impedance of 3.6 Ohms. That's not too low?

Bob,

I do not know. However, many speakers have a transient drop to low impedence's which is probably not a problem. If however, there is a sustained drop to really low levels, that could be a problem. OTOH, if you do not play really loud, then the demand should not be that great.

Also, my Yamaha had a switch on the back for 4 or 8 ohm speakers, does you HK have one?

George: No switch on the back of the receiver. How loud is really loud? I don't think I'm hitting reference levels playing movies.

Thanks for the input. It's appreciated.
