Integrated or Receiver?

That is the question.

As my luck would have it, my near 30 year old Denon PMA520 integrated amp is apparently on its way out.  I've already spent $150 to fix one problem only to have one channel all but vanish (can hear some high end audio but it is faint) and the other channel cuts in and out.  Since I had the unit cleaned just a few weeks ago and the noise that had cropped up in deep bass, I would have to believe this is another problem and would require additional servicing at additional cost.

The way I see it, this is throwing good money after bad.  Will probably scrap this thing and will buy something new.

Since my budget is going to be under $400 right now thanks to a slew of other expenses that take priority, I am wondering if I should just settle for a basic entry level amp like the Yamaha 301 or Onkyo 9050 or purchase a Receiver from Yamaha or some other company that is fairly inexpensive and use that for a couple of years until I can buy a better integrated amp when I should have more money to budget for it.

Any thoughts on this?

Difficult to find a budget integrated amplifier that will effectively drive 2 pairs of speakers at the same time. Both speaker pairs would have to be 8ohms or better across the frequency range. Few are. Many would have connections for 2 speaker pairs with a selector that would allow you to choose a speaker pair to listen to individually.  My cambridge Audio 540C will allow this. I would not rum 2 pairs at the same time however. 

If an integrated has pre outs you could run additional amplifier to the 2 pair of speakers. If the additional amp has gain controls you could then adjust the output of the 2nd speaker pair relative to the 1st pair.

Thanks for the added info on the subject of running four speakers.  Got away with it on the Dayton amp but won't even think of trying it now with the real amps.

Oddly enough, I just got home from work and plugged in my headphones into the Denon PMA520 and started to play a cassette tape.  Suddenly it is functioning perfectly again.  Last night and yesterday afternoon I lost one channel but the other worked and then later in the evening I lost both channels.  No audio at all.  But now this evening it is working perfectly.  

Weird.  Will still shop for a new integrated or receiver but will hope in the meantime this Denon will last at least a few months.  It would allow me to save more money and budget more for a better amp.

Yes, I am looking at the new Yamaha stuff now.

One problem I am running into is trying to find a amp or receiver that will allow me to Biwire my 6 ohm Mirage OM 10's.  Every amp or receiver I've looked at can't handle the lower impedance except when the OM 10's are not Biwired.  My Castle's are 8 ohm and don't present that problem

The Yamaha can handle it. I've used both sets of terminals to bi-wire 4 ohm speakers and it didn't break a sweat. In fact, you want to leave the impedance switch in the 8 ohm position when running such a configuration.

And this one:

BTW, the amp section is essentially the same between the 501 and 801.

helomach.  Thanks.  

I've read a number of reviews where people claim the newer Yamaha amp's sound bright.  What is your opinion of this?

Mesch mentioned Cambridge Audio but upon review and reflection from a previous Cambridge amp I owned, it was too clinical for my taste.  A bad matchup with the Mirage speakers.  The sound was not really neutral and grated on my ears every bit as bad as the Yamaha A500 and Klipsch Heresy combination I had in the 1980's.  

I would prefer to find a neutral or slightly warm amp vs. one that is either bright or clinical sounding.  A wee bit bright probably would not present an issue but one that is heavy on the bright sound won't work.

Just checked the manuals of a couple of Integrated's.  Looks like Onkyo amps need at least an 8 ohm speaker for bi wiring.  But Marantz says  a 4 ohm or higher will work.  Same with Yamaha.  That is good news.

Will hope the Denon can last a few months until I can come up with enough money to get a pretty good integrated.  Should be able to spend over $400 if I don't have go and get one in the next month.
