Replacement for a Marantz SR-5000

[jspenn]

I purchased a five CBM-170, one VTF-2 system and was running it with a Marantz SR-5000. About six months after the purchase, the Marantz fried and I had it repaired. About six months after that, it fried again. So instead of fixing it again, I'm in the market for a new receiver.

I think I had problems with the SR-5000 since the CBM-170's have 4-ohm impedance and the high current flow was more than the receiver could handle. So, what are some midrange ($400-$600) receivers that are specifically designed to power low-impedance speakers? I'm considering the H/K 525 (if i can find a deal) and the Outlaw 1050 (what is this about a 1070?). I've heard NAD is good, but I think they're out of my price range. Any other recommendations? Has anyone else had a problem with the low impedance?

The average impedance of the CBM-170 is 8 ohms.......any AVR in your price range should not have a problem with them.

I am partial to HK and NAD, but many people have had great success with Pioneer, Onkyo, and Outlaw. The Outlaw 1070 is the replacement for the 1050, but I do not know when it is due for release.

I loved my HK 525.

The CBM-170's are actually rated for an average impedance of 8ohms. Though by the spec charts they certainly look like they dip into the 4 ohm range a lot.

I run 170 mains with an Outlaw 1050 and love it. No problems since getting the 170's 3 years ago(+/-)!

The 1070. I suspect, will be here shortly. Look for it after the NY CES show.

Expect it to cost around $800+.......just a guess.......as the 1050 was $599 new, and then went down to $499 when I bought mine.

Oh, I was mistaken. If not the impedance, what could have been causing the SR-5000 so many problems? What should I look for in a new receiver that might keep this from happening again?

Try to get a receiver that can handle down to 4 ohm loads. Even some of the lower end Sony's can do that, though there is a switch on the back that needs to be thrown. Heck, even my Denon 3803, which was a $1100.00 receiver when it was new, is not made to handle 4 ohm loads, and there are plenty of warnings in the manual about it. Though I have not had any problem running my 340's and 170's on it.

What exactly did the repair shop say they had to replace?

It is possible that you need better air circulation around your receiver. Where is it installed currently?

If I recall correctly, they had to replace a few transistors. The receiver was installed on a counter with nothing on top of it, so it was getting adequate circulation.

Maybe I was just running the Marantz too hard? If so, are there any affordable receivers out there that would support my desired power output (comparable to what the Marantz could handle, but hopefully a little more) and work well with the 170's? I think the SR-5000 was rated at 70Wx5 continuous.

People run the 170's with 8ohm rated receivers all the time. Also, 70W per channel is plenty of power. Something else is at work here. How loud is the music at your listening position and how far away from the speakers is it?

I never listened to music too loud, but for movies I did. The room is about 15 by 15 so I'm about 10 feet from the speakers. At that distance, the volume was considerable. I don't know decibles, maybe 105 or 110. Enough that you had to yell to be heard during action scenes.

I would check your speaker wire for good clean connections and no frayed ends, at the speaker and receiver.
