Marantz 2325's interaction with 4 speakers/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.

Why don't you consider getting a pair of Paul Speltz of Anit-Cable fame's new Auto-Formers. These would bring the impedance created by two 4 ohm speakers in parrell resulting in a 2 ohm load that the amp would see, back up to 4,6 or even 8 ohms depending on which taps you use. Another option for you. Also some of the early multi speaker boxes from Niles allowed you to hook up up to four speakers while maintaining the proper impedance by pushing the correct setting on the box for "multiple speakers" attached.

bartokfan, was that $250.00 an hour, or $2.50 an hour?LOL!
