Does anyone have one, or know much about them?

I looked over at avsforum, and there was a 200 and something page thread about it, and honestly... I did not feel like reading 200 pages worth of responses....

Thanks

Dak, I don't know anything in particular about the 7005 except that it looks a bit overpriced to me. Even if you're looking for a pre-pro, it would seem to be more cost effective to buy one of the Denon or Onkyo factory refurb receivers in the $1000 area.

John, one requirement is balanced outputs...

Denon's processor has balanced outputs, but it also costs 7,000$... and i am not going to pay 7,000$.....

I liked the Marantz, because it was under 2k$.. somewhere under 5k$ is my budget for a new processor when i upgrade.

Okay, if you really need balanced outputs, then the Onkyo 3008 or Denon 3312 that I had in mind wouldn't be suitable. What's the specific reason balanced is a must, since generally it doesn't seem to be of significant benefit in ordinary home environments?

I noticed a large difference in my house, originally i was running RCA's to the amps.. However there was noise.. When i switched to balanced the noise is canceled out due to the 3 wire system of a balanced cable. The processor i currently have is a very good one, and there are copious amounts of filters ect to eliminate any noise.. So i don't know why i had noise on the line.

i also had a ground loop problem as well, The axoim ground loop isolators fixed that... The house was built in 75.. So it could be the wiring in general, i don't know for sure. however, i will be sticking to balanced outs on my main system.. My bedroom system is using rca's to the amp.. But that system has speakers similar to the M2's so any noise in the signal isn't as apparent as it is with the Vp-180/M60's

Loc: Texas(DFW)..that country to th...
I don't know about the 7005 but a few weeks ago I bought a Marantz Sr-6005. It is now on it's way back to Marantz for a refund. I bought it to replace my 4 yr old Onkyo (which has been great). I took a chance on Marantz because of all the reviews touting their build quality. There were several things wrong with it: 1. There was a startlingly loud pop every time it was powered up. I went through and disconnected my sources one by one but it still did it with no sources hooked up. I still don't know the reason for the pop. 2. One of the analog inputs didn't work. 3. I didn't like the user interface (maybe I was just spoiled with the excellent one on the Onk.). 4. The strangest problem was that when it was in Pure Direct mode with analog out from my Mac Mini using either Decibel or Audirvana or Itunes music players the Marantz would not respond to either mute or voulume control from neither the Marantz remote nor from the Harmony one. But if any other programs were opened on the Mac Mini it would work. However, it would respond if it was in any other listen mode other than pure direct. I'm still scratching my head on this one. If anyone can enlighten me...please do.

I took the Marantz out and put my Onkyo Tx-Sr 706 back in and all was good again. I will probably get the Onkyo Tx-Nr809. My current Onk 706 has been a work horse (used as a HT pre amp).

The Marantz felt like a light weight compared to my Onkyo and Denon. My perception was that the build quality (both inside and out) was not any better than the Denons (two older units now used in bedroom system for the kids) or Onkyo that I own. Maybe even slightly less. Just my opinion but I'm no expert. I will say that the Marantz was pretty.

i have a 2 months old SR5005 and use it as a pre-pro.
i do have a medium loud pop when switching the thing on.

i wrote to Marantz and they said this:

Hello Jacques,

I would say that issue does not fall under normal operation as our 5005 here does not perform that way when using the pre-amp hooked up to an external amp. I would recommend you have an authorized technician look at the unit to properly diagnose a physical issue or being that you recently purchased it, please check with your retailer's exchange policy.

Thank you,

******************************

I got the sales manager on the phone at the store where i bought it and he said that it is normal to have such a pop.
what i must do is switch on the Marantz first, and then the amps".

this is just sales talk from someone who does not seem to know that repair does not cost the store a cent, it's under warranty.

i will not have it repaired or exchanged, because it does not bother me to switch on the pre-pro first and then the amps; i've always done that...

but it could be a problem when it's used as a receiver, as the amps can't be switched on later, after the preamp has stabilized.

hope this helps. :-)

Hi,
I have a firend who also uses the Marantz SR5005 as a preamp/processor and it does the same thing. The remedy was to turn on the Marantz first. However, I recently installed a trigger on for his power amp which is initiated by powering the Marantz and it works without inducing the "POP" irritating noise.

That's because it's turned on after the prepro. I do this without any problems, which should be the norm without the trigger.


I actually turn the volume right OFF before I shut the system down, then when I turn it on....no wear and tear when you fire it up.

I have found that if you are using separate power amps it helps to have some device that will have a "delayed-on/off" capability(a power center or equivalent device). This eliminates the "pop" in the speakers from the amps. It is not the AVR, its the amp.
