Marantz av10 and amp 10

[Simon1234]

I've just upgraded from my old denon avr 4520ci to the marantz av10 and amp10 and I have questions I'm hoping someone may be able to answer. I'm currently running 9.3.2 but will be adding in ceiling speakers within the month to go full 9.3.6.

My questions mainly are about the amp10.

When connecting the speakers I have connected channel 1 as front left but then I connected channel 2 to say the surround back right. I did this so it's unlikely channel 1 and 2 that I hear share power will be active at the same time allowing greater pull of power to that channel. Does this affect the imagining in stereo mode or put strain on the amp being different loads?

Secondly I've noticed especially on the floor standers that at all levels there is a slight static/ white noise coming from them. I don't remember that from my old denon. Now while I'm just being picky and honestly it's not obtrusive and cannot be heard unless you put your ear right up to the tweeter I just wanted to see if this is normal.

One last question about Dirac. I'm waiting for my inceiling speakers to be fitted before I calibrate using Dirac and wondered if anyone could describe how much better if would be?

System:
Marantz Av10
Marantz Amp10
Focal 836v Fronts
Focal 800c Centre
Focal 816v Surroumd backs
Focal sr800 Front height
Focal sr800 Front wide
Focal sr800 surround
3 x Focal 800 subs in FL/FR/Rear

4x Focal 300 ICA6 inceiling being fitting in 2 weeks.

I would just keep it simple and not worry which speakers you connect to which terminals. There is only one power supply and the unit is only 200 watt per channel, two channels driven.

There is one power supply, so if that fails all channels go down. The amps are arranged in pairs on each board, but they are discrete on the boards.

This is not the sort of unit that would tempt me, as you could easily lose all amps in one point of failure on the power supply board.

I just had a five year old Marantz 7705 AVP fail after five years. Turns out there are no parts available after phoning two authorized repair centers. So I bought a 7706, my dealer was good to me a gave me close to a $1000.00 discount. So, this sought of attitude to service is not good enough.

I use just two channel amp, nine of them for 18 amp channels. They are all Quad.

I would personally not risk 14G on an amp 10 and AV10. For that money there should be cast iron guarantee of service for at least 15 years or replacement with current model.

The (slight) hiss you hear ear-to-speaker is common with high sensitivity speakers like focals. It can also be increased by a higher gain between AVP and your external amp. If it bothers you and the amp10 is within the return period you can swap it out for another amp which might not have a hiss. Or you could try a less sensitive set of front speakers.

Thankyou, that makes sense.

I have floorstanders front and rear. They seem to hiss louder than the surrounds and centre. I swapped around the channels on the amp10 and it didn't chamge a thing so it must be just super sensitive speakers.

It doesn't bother me and it sounds incredible so now i know theres nothing wrong I'll probably leave it. I may play around with the gains from the av10 l, bring the whole system down a dB or two see if that makes a difference.

This is NOT true as you can see in my review. The amp will deliver 200wpc with 1 or 7 channels driven into 8 ohms. The supplies are tightly regulated so there's no sag.

Marantz AMP 10 200 Watt x 16CH Amplifier Review!

The Marantz AMP 10 is a 200 watt x 16CH amplifier utilizing the ICE Edge Class D topology with a custom built SMPS power supply. I put the AMP 10 through exhaustive bench tests to gauge its performance.

I run all Perlisten speakers (90+dB sensitivity) and hear no hiss and certainly no static from my AMP 10. Are you using XLR or unbal? Make sure the input gains for each source on your processor aren't turned down below their default dB setting. The AV10 and AMP10 combo produce incredibly low noise and distortion so what you're experiencing is very atypical even with high sensitivity speakers. Swap the channels on the noisy speakers and see if it improves. If it does, it means your amp might be faulty.

Thankyou gene, it was your review that prompted to purchase this combo.

I have swapped channels and no change, the focals front and rears are 92db sensitive. And the hiss is from the tweeters and you can only hear when your ear is within 30cm. I'm running rca connections but oddly enough when tested in 2 channel stereo there is still a hiss from the rears indicating its more likely the amp10. This hiss seems to be across all channels.

I'll be contacting marantz customer support to get some feedback.
