Marantz SR4001/5001/7001/8001 - Page 91

post #2701 of 2839
well, just in case anyone is interested, I asked Marantz about why "stereo" mode with no EQ sounds different than "pure direct", their answer:

It is always likely that you will prefer the sound from Stereo than Pure Direct. Because in Stereo there is still some processing done by the receiver, where in Pure Direct, it is playing what it gets from the source. Many times what a recording engineer has laid on a track may not sound good as "raw" information in Pure Direct. While using stereo basically colors the sound.

It's the bold print that I wasn't crazy about. So Marantz does in fact use somewhat of a "house curve" as I like to call it. There is some level of EQ'ing even with no EQ. They're "juicing" their gear. Not the answer I wanted to hear. Oh well. It does sound good. If I ever get my turntable situation worked out (which is another headache altogether), I'll find out how vinyl fairs.

Thanks.

A lil late for this but I had the same problems. My 8001 went dead on me 2 times (serviced twice)... and this time around, it started to act up again. I called Marantz before the warranty went out in 2 days. They agree to sent me another refurbished 8001. I've just received that today. It came with the newest firmware h.55. I've been playing with it for 8 hrs... so far so good...

Give them a call if you haven't already done so...

Al,

Al,

My 7001 is in the shop for the first time for exactly the same thing. Hopefully, they'll get it corrected.

I hope it wont happen again after the repair for you like it did for me. Marantz did take care of my problems but everytime it went dead I have to send to NJ for repair. The process took about 3 - 4 weeks. That's like almost a month without music/movies. So this time around, I biatched at them and they agree to give me a replacement instead. They also said that my unit tested okay. There's no sign of "protect" mode on or power problems. They blamed on my system instead but still gave me a replacement. The thing is I have no issue with my Pioneer receiver prior switched to the Marantz receiver.

Good luck on yours. I hope everything works out good.

Al,

I didn't know so many folks were having issues. My SR8001 shuts off at random times. It has been in and out of the repair shop for the last three months. Currently it is on its third visit to the repair facility. Hopefully, they will send me another unit.

I wouldn't say it "many". Yeah, it happened to me, you, and a few others... but that's not many compare to the amount that they sold. Anyway, in your case if it happens again after the third repair, I would talk them into giving you a replacement. They won't say anything unless you request a replacement. It has to go to a supervisor for an approval.

Al,
post #2707 of 2839

True.....I'm sure they have sold a lot of units.

Initially they were trying to blame the issues on other components, but, when I informed the repair facility that I had purchased a new NR1501 and it was connected to the same equipment in which it didn't have any issues they went back to work trying to find source of the problem with my 8001.

On the last go, I thought everything was working good with the 8001, so I sold the NR1501 (I would have liked to keep the NR1501 and sell the 8001 but, the 8001 powers my speakers and room better while watching movies). Oops....I should have waited.

post #2708 of 2839
I hope they don't try to blame it on my system, since the 4001 that preceeded it and the Onkyo 707 temp replacement had and have no problems. It also stayed in protect with no speakers connected. Speaking of the 707, I really want the 7001 back. Even though they both have Audyssey Multi-EQ, the 7001 sounds so much better than the 707 with my Polks.
post #2709 of 2839

I'm glad to hear that you perfer the 7001. My dealer closed....so no free loaner for me....

Like you, when I got my 8001 back the second time, I did not connect it to any equipment. I simply had it plugged into the power strip and within fifteen minutes it shut off and would not power back up.

You guys are scaring me. I am still so pleased with my SR7001. I dare say it has truly been a dream audio product for me the past 5 years. It doesn't get the greatest ventalation either and it gets pretty darn hot if I screen a couple of movies in a row for sure and I am not even using the L/C/R amps at all right now.
post #2711 of 2839
Called the shop this am, although they didn't specify what, parts are on order and I should have the unit back at the end of next week. I'll try to find out what the problem was and report back then. JOHNnDENVER, I use a Antec AV Cooler on top of mine and it keeps it nice and cool.

I suspect that most units do function like yours, flawlessly. Personally, this is the first time I've encountered a problem with an AV receiver. All my previous Marantz, NAD, and HK's have worked perfectly. All of my receivers, including the 8001, sit in a rack with excellent ventalation.
The 8001 is a really good sounding receiver with a ton of excellent features. Now I just hope that Marantz will take care of my issues for good. I don't want to have to send this unit out a fourth time.

Where did you send the unit for a repair? Marantz paid for the shipping on my unit to United Radio in NJ for a repair. Supposedly they did all kind of testing and updated your firmware before sending it back to you. That's what it said on my repair report. They even list out what components they replaced/fixed. They supposed to do the "current" test for a few days to make sure everything works okay. So for you to just power up the receiver and got the same "protect" mode shut down within 15 minutes then that repair center did not do their job correctly. Talk to Marantz about your problematic receiver and state your frustration/inconvenience for you to keep doing this... Demand a replacement unit for all the troubles you've been through.

I've got the replacement unit for 3 days now. It works flawlessly so far (knock on wood). I'm enjoying music/movies again This 8001 receiver put out some beautiful sound... I'm loving it

My 8001 went to Northridge Electronics, CA. for the first two repairs. It is currently at Service Wide Technologies, IL. for it's third repair. If it is not fixed this last time around, I will be requesting a replacement unit from Marantz.

I'm glad your new receiver is working good. I hope you have no future issues.

Likewise with my 8001 - I had 1 issue at the start due to the voltage sensor being too sensitive for Aussie 240v and once replaced it has been flawless.

I would like to upgrade to an 8002 for the THD & DTS-MA decoding tho.

Player decoding not cutting it for you? Right now I see no real advantage for it is all.

My Oppo 83 has excellent decoding but the HDMI + LPCM Jitter issue seems to render the sound a little lifeless in comparison to bitstreaming to an AVR (a mate has a 7002 and a similar setup to mine).

I got my SR8001 back. They replaced the amplifier block. It has been running for 48 hours straight without any issues....an improvement over previous repairs.

Don't forget that speaker and room configuration usually make a much greater difference in what you hear than the electronics does. So if your friend's room is different, what you hear will be different. Having the sound level very slightly higher also makes it seem to sound better.

True, my litmus test is SACD's which both my Oppo and AVR can decode natively and DSD straight thru to my AVR has far more life than decoded to PCM by my Oppo.

Owners of the SE Oppo (same decoder, different analogue stage) report that the DSD decoding of the Oppo is superb and lacks nothing via analogue but decoding to PCM over HDMI is lifeless - the common denominator is HDMI which reportedly due to the way PCM is transmitted between the video data (jitter).
post #2721 of 2839
Got my 7001 back from the shop today. The problem was a defective heat sensor was triggering protect mode. Hopefully, the replacement corrects the problem. I was happy to see all my settings, etc... still stored in the setup menu. I'm even happier hearing it.
post #2722 of 2839
I wonder if manufacturing date has anything to do with it. My 8001 has been going strong for over 2 years and it was new "old stock" from secondact... maybe one of the last new ones built? Came with h.52 already loaded. The only issue I had was going into protect mode with "dirty" power, but an AVR UPS (SUA1500) fixed that and it hasn't happened since.
post #2723 of 2839
My refurbished 6001 had the same problem when I first got it (going into protect mode and finally not coming out) - I ended up sending it to Service Wide in IL and I've had no further problems. The guy that I spoke to indicated that it was a defective heat sensor and said that it was a "known issue" with these units. I'm not certain whether this means just the 6001 or all of the x001 models.

How do you find out what version of firmware you have on the 8001?

By pressing simultaneously Pure Direct, 7.1CH input and MultEQ Buttons for 3 seconds. These buttons are on the receiver and not the remote.

In Service mode pressing enter shows version numbers for different components.
post #2726 of 2839
I've been reading this thread and the SR7002/8002 thread, and I'm wondering if the 001s had the so-called "-9db Audyssey subwoofer" bug? I haven't seen it mentioned here, but it seems odd that a bug would be in the later models but not the earlier. Anybody know?

So you don't use Audyssey? With the 8002 you can use one or the other, not both at the same time.

Actually I do but iirc you cant use Audyssey on 7.1ch LPCM with an 8001 either as it's disabled in that mode.

I did not know that - thanks. I assume that you can with the 8002?

The only differences between the 7/8001 and 7/8002 afaik know is the HDMI chips are v1.3 and the audio decoders have been upgraded to decode DTS-MA & Dolby True-HD.

The limitation is caused by a lack of DSP power preventing Audyssey being applied to high bit-rate codecs.
