    Buzz/Hum Issue from Preamp?

    I have a similar issue with OP. I haven't had a chance to fix it yet but it's irritating me lol. CA 740A integrated amp input into pre out of NAD AVR. Using HT bypass (fixed gain) for 2 front L/R speakers. I can hear like a whine/buzz from front left speakers when CA and NAD switched on. Can only hear it up to 40cm from speaker. I set the CA to a fixed gain of -8dB. If I turn this down more and more the noise goes lower. I haven't changed power cable from NAD to test yet. I have changed Analogue interconnects but no difference. When using other inputs like my CD player in the CA, no buzz at all. Only when selecting the HT bypass input. Any ideas?

    Budget around 2k. Don’t see any used version 3 around. Maybe too new.

    I want to have both good 2 channel and HT but in one box if possible

    NAD 758v3 or something else?

    Thanks. What if I purchase a 2 channel or 5 channel power amp and use that with the t758?

    NAD 758v3 or something else?

    Thanks. Do you mean the bigger difference between the NAD avr and integrated amp would be pre amp section? Or the power section? Or both?:)

    How does this receiver perform in 2 channel compared to say entry level to mid range integrated amps? Say Rotel, Cambridge Audio type of integrated amps. 70W-100W X 2

    HT Bypass issue

    Thanks. I don’t have any keyboard or mouse connected to it. I use the built in IR to control. The weird thing is I don’t think there was this sound when I used the Pioneer AVR but maybe I wasn’t looking for it! I will connect another htpc to it and let’s see if it makes any difference. Not a big deal as I use the oppo for playback of media files too.

    HT Bypass issue

    I only have one power supply for the nuc. It doesn’t have optical out. Only hdmi.

    HT Bypass issue

    Ok update. I removed all hdmi from NAD and whining interference sound is gone. I plugged in 1 by 1 and the intel nuc was the culprit. Not sure how to fix this? I tried different hdmi cables and also used the same cable as Apple TV 4 which did not make a whining sound but when used on the nuc it produces the sound. Any ideas? I don’t mind not using the nuc but would like to know why.

    HT Bypass issue

    Hi all, Has anyone used the pre out for the main Front L/R speakers on the NAD T758 AVR? I tried it connected to my Cambridge Audio 740A integrated amp which has HT bypass via fixed gain to make use of the power section. When I set it loud enough on the CA my main speakers have like a high pitch whining sound. You can hear it about 1 meter back. But when I switch to another input with no fixed gain setting just regular CD on the integrated amp it’s fine no matter what volume. I had a Pioneer SCLX71 AVR before this and no issues. Using same cables etc Anyone know what’s going on? Note: mine is the original t758 with the am100 and vm120. Thanks, K.
