AK only has marantz of the 22xx vintage

"I am sorry if my comment was misunderstood. I was only trying to offer a solution to the concern that was raised. I agree that the lion's share of Marantz forum talk centers on the mentioned models. And if there was a specific forum for Acoustic Research, the same sort of "favorites" would get the most plaY

No need for apologies, Were Big boys, We can dish it and take it! You know.. For a Stupidhead, Your actually a Nice Guy.
 
Just in case anyone is wondering, Stupidhead (Geoff) is a friend of mine!

I don't think there's a rule, either written or non-written, that precludes discussion of any other types of Marantz gear here. It's just that it doesn't really pop up for discussion too often.

If he's got someting to say about it, let 'er rip. We're all ears.

I'm from Kuala Lumpur,Malaysia and this is my fav place to hangout.:smoke::D
And yes,I'm partial to vintage Marantz. See my signature .

I agree with you on the big Marantzs. It's not AKs fault or the people here, the US simply didn't get any numbers of those amps so they are relatively unknown on the forums. I have a PM94 and PM95 with the PM94 about to become a mosfet donor to the PM95. There's a channel out in each amplifier and I like the PM95 better.
I can help you- send me a PM.

guys put your guns down . im not trying any sarcasm . i know this is a big ol forum .and iv been on this forum for a couple of years . i enjoy it . its already a broad one with lots of variety .whenever i try googling any audio stuff , it generally brings up AK contents . that shows how big it is.
secondly , my query had been about a couple of marantzes that i always wanted to own but never found em in my market . the esotec PM 8,and PM 94 are those models . Iv found these two names very rarely making the headlines on the AK front page . Does anyone agree? . although they were best marantz models they are scarce here.
anyways .
My local audio market brought up 3 marantz pm-94s . they were in need of a number of repairs . the fried transistors being the common issue in all 3.i learnt a great deal about the 94s heating issues and its simple cure as well. but the problem with market here is lack of those MOSFETS. the amps are collecting dust in that shop from a year now and still the tech cant find the required transistors . and is simply not cost effective ordering them from abroad . it would simply be equal to the cost of the amp itself .
seeing that i wondered if 94s couldnt be restored , it would be risky to own em . and at the same time i also had sansui 907 imos limited which also is mosfet powered. and my tech says its got the exact same mosfets . hence if these ever got fried, the sansui would be sharing a similar fate as well. oh god !!!

I have to "separate" myself from you guys...

"Separate" the man from the boys.....

3 degrees of "separation"

"Separate" beds....

"Separate" but equals....

"Separate" ways....

You got to get them "separated"....
 
:lurk: Since AK is primarily US based, you'll find a preponderance of the Marantz models that were built for and sold to the US market discussed. Also, most of the older AK members who grew up with Marantz US models are more familiar with the 1960-1980 models. As Marantz got sold to Philips, a lot of the interest in later grey or black 80's models that were sold in the US or Europe just didn't generate as much interest.

However, the Esotec series, especially the tuners with scopes, and many of the Marantz home market products were still the real deal but were seldom seen in the US except for those folks who were able to catch a few Japanese magazines that showed them in advertisements.

Now that we're so much more interconnected by the internet, AK members are from all over the world and we have access to more pictures, some literature, and much more experience (aside from country specific forums similar to AK) to benefit from.

Best thing is to post you questions about the Marantz model in question, especially pictures, and we'll all learn more.

Are equivalent outputs to the PM-94 really that hard to find?

Your Sansui will not blow up just because it has MOSFETs. They can only blow from abuse, such as the heat issues the PM-94 in particular tend to suffer from (it runs in class A, which is serious business temperature-wise).

That Sansui isn't a class A amp so it's not likely to run hot at all. Also, it's not super infamous for blowing up, unlike the PM-94. :D
 
Yes, they are nigh impossible to find originals. There are thousands of fakes, with most of the fakes so good, you cannot tell them visually apart. I know, I have plenty of them along with some originals.

There was a suitable equivalent, but it's also EOLd now too.

I know of one only source for the originals and they are expensive, so I made the decision to scrap my PM94 to keep my PM95 alive (they use the same MOSFETs).

As for MOSFETs in general, I find them brilliant but brittle- they self destruct more often than they should, sometimes for no reason and when they do, they take out all their friends due to the way they fail.

The PM94 actually doesn't run that hot, the heatsinks are more than adequate, it was a combination of dry joints, multiway connectors and in my opinion, flaky MOSFETs that result in the premature deaths of them.

how about matching of various speakers with 94 . is it better than 907 at that . i couldnt enjoy 907 as much due to its sheer tightness of sound and accuracy . its almost non musical with rf3 .
 
Can't comment on the AU-D907 other than the ones I have (AU-D5, 7 AU-717 etc). I like them, but they are uninvolving and I simply don't listen to them anymore- I got bored with Sansui years ago. I spent too much time fixing other people's brown goo related issues in Sansuis over the years and endlessly replacing bulged filter caps. That's not to say they aren't wonderful amps, but they need attention more than some other TOTL amps to sound their best.
If I were you, I'd consider the 3 PM94s if you can scoop them all up for a bargain, ship them to a real passionate tech and repair them all back to full spec. Then possibly sell two and keep the prettiest one for yourself. You'd end up getting it essentially for free then.
If you can find anywhere a PM95, it is better again, that is unless you want a phono stage as it hasn't got one- it has a single crown TDA1541 Dac and class A/AB discrete switching instead of the AVSS auto switching in the PM94.
 
There is a 510 m Marantz amp on eBay right now, that is bringing some good money. $1265 with 5 days left. It is awesome looking.
 
my pm6 is back

wooo hooooo.
guys tonight my pm-6 got back .
i played it . i loved it .
needs little deoxit though . . dont have it . damn .
