Excessive hiss with AV channel on Nait 5i
Posted by: Flame on 17 November 2007
Hi all...
Today I connected my Nad T753 to my Nait 5i's AV channel and had the "unity gain" enabled. I will be using this setup to watch DVDs.
I was surprised by a pretty loud hiss from the two front speakers (the ones powered by the Nait). No his is present at the center or rear speakers which are driven directly by the NAD. Hiss is present regardless of the source feeding the NAD. I switched to a different power outlet in the wall (for the NAD) and things didn't change. The hiss only goes away when I "mute" the NAD or bring the volume down to -infinity. The hiss doesn't increase with volume increase either. I got my dBl meter about 2 feet from the speakers and the hiss is registering 55dB. Kinda loud ain't it?
Anybody has had similar issues? Oh by the way, connection between the two is via Chord Cobra 3 RCA cables. Didn't have the same problem last month when I was trying out the Nac112 with 90.3 But then the connection was made to the DIN AV input (with cobra 3 custom interconnect). Dealer will visit this evening but your input is (as always) very helpful. Thank u all

Check this out guys;
Dealer came. We played around with the connections. First of all my Naca5 cable with "F" speaker ends sounds amazing. Much better than the chord cables I had. As for the hiss, Thomas (from mate Hi-Fi) was pretty surprised. Moreover, I was surprised when we found out that the hiss was only present on the AV channel. We connected the NAD's pre-out to the tape-in and tuner-in on the Nit and they didn't exhibit the same hiss. Actually, they were extremely quiet. We don't know where to take it from here, but for sure things are gonna get interesting

huh?! Slug???? 
Nait5i has been picked up by the dealer. email sent to Naim. Most likely, a 122x/150x is arriving in a couple of weeks (will be significantly poorer
