Question Marantz av7202 mk 2

[yorkshire rose]

Hi I am looking at buying this amplifier, to replace a pioneer lx85 amp. Would it be a straight swap or would I need to buy other devices for it to work? Thanks

Hi,

'Presuming' you've made a typo with the model number and you mean the AV7702 ?

If so, this is a Processor and won't directly replace your LX85. You'll need a multi-channel amp to go with it.

Yes it was a typo, so would the marantz 7010 be a direct replacement! Thanks

 

[DodgeTheViper]

Yes it would

If I bought a 7702a amp what else would i need to buy? Thanks

A power amp(s) covering the number of speakers you have.

A power amp(s) covering the number of speakers you have.

I want to have 5.1.4 surround sound, do I need to buy a power amp for each channel, this could get very expensive!!

 

[stevos]

In a word yes.

So you need 9 channels of amplification.

You could buy for example a 7 channel power amp and then a stereo power amp for the missing channels, or you could go for two 5 channel power amps (1 wasted channel but haho).

Alternatively you could buy something like this, which has 11 channels, so you could go 7.1.4 or just bi-amp your front speakers.

Is keeping the lx85 an option? Does it still work?

It has multi-channel input and 7x amps that you could utilise for surround / height channels. This would reduce the number if power amps you need immediately and you could replace it over time if desired.

 

[stevos]

A pretty good idea. Going with a decent 3 channel power amp for the front channels would be a pretty upgrade. Surround sound channels are less important.

Hi, thanks for the replies, unfortunately I got rid of the LX85.

Is an all in one like the Denon X7200WA the way to go or would the Marantz 7702A with the necessary power amp be a better sound quality. Albeit this route would probably cost twice as much.

 

[stevos]

It depends on your speakers, if they aren't of the same level then your wasting money.

I've recently made the move from an AVR to separates (Sherbourne PT-7030 + Emotive XPA Power Amps). Logically and practically, I find this much more sensible and flexible. When all the hoo-ha over height formats and HDCP and HDMI versions settles down, I'll upgrade the processor and keep what are fairly fine amps that work well with my speakers. I expect to keep the amps for years to come.

If purchasing all those over amps seems daunting or expensive, go for a really good stereo power amp (or mono blocks) for your front L/R and pick up a second hand receiver for other channels. It doesn't even have to be modern - you only need multi-channel input capability - it doesn't even need to have HDMI so you can go back many years and get a real bargain.

Good luck!

Hi, is there a sound quality benefit of the 7702 mk2 or the avr7010.they look pretty similar on paper!
