Marantz 2325's interaction with 4 speakers/load?

Rich, that the 22XX series could handle 2 sets 4 ohms speakers may be true in its first years of life, but as Jea48 mentions, the "old faithful" is going on 30+, so I don't want to press my luck. I'll use the 2325 for the Thors only, buy a second Marantz(not sure which, maybe the 2265) as a biamp for the W26's. Thats probably what I'll do. I'll follow up on the links, thanks for the links. Funny how the more things change, some things remain the same, The Marantz 70's quality still shines, as witnessed on the reviews. I'll keep everyone posted on the results. I think the Thors will take a toll on the Jadis, as I need to put the treble all the up for proper dynamics to come in on the Thors, without music on, vol up all the way+treble up all the way, I hear a pretty loud hum comming from right channel. Not sure what that is, believe it started with the Thors last month. I'll have a tech ck it out.But as I say, with treble down alittle, the hum fades greatly. The tone controls on the Jadis are not like those on ss units, basicall its an on/off setup, with no gain increments.

You will have no problem running your Thor`s with the 2325.It will easily handle the 4 ohm load.

Thats great news. As i say, back in 1975, all I could afford was the Marantz 2015, since I was only making $250 an hour clearing window air conditioners down here in New orleans during the summer. I totally forgot the Marantz amps, as I was searching Audiogon for a reasonably priced Elecrto, then the idea hit me , the old Marantz's. There's quite a few on Ebay, all models. I'll certainly keep everyone posted as to the meeting of the great from the past(2325) and its showdown with a great in the present, the Seas'. If the Marantz made all those BOMB speakers sound good, you know the ones we all had and thought sounded "far out man", just think how she'll do with the Seas'. Gonna be exciting. Now I fully, completely understand what folks were telling me about getting the right amp for the Seas'. These 4 ohm, 87db Thors work better with ss amps. Like everything in audio, there's a tradeoff. If you have a power hungry speaker, you may do better with ss amps. As much as I like tubes(will get the Cayin 500MK in future), the Marantz may be just the thing to unlock the dynamics in these Seas'. Cheers

Do not connect 2 sets of speakers at 4 ohm or you will blow your output transitors, I know I have done it. The Marantz 22/23/44/43 or any were not designed to run at 2 ohms because you sacrifice Fidelity. The best sound is acheived by running in 8 ohm; 4 ohm kills headroom oh 8ohm amps and 4ohm speakers don't keep the electricity in the coil long enough. The last statement was told to me by a the smartest man I know of he has a PHD in several fields(electornics,Math,ect) and designs Flight simulators for fighter jets.

Well, even if the 2325 is powerful and resistant, I wouldn't try to connect such low load (6+4 in //) expect if you promise to listen at very low level (ambiance style). But you mention an efficiency of 87db (small speakers I suppose), that mean that you will need sometimes to increase volume, and face overload problems in your output stage, that is to say : dangerous current increase and peaks in the output transistors, and then risk of overheat and/or blowing. Stay wise with 4 ohms, and I agree with brose@echosat : nominal Z at 8 ohms is safest and furthermore better, because it provides less damping to the system, which is always overdamped usually. Yours Sincerely.
