Pioneer SX-5590

This Pioneer SX-5590 is the European version of Pioneer’s SX-1250.  It would definitely be considered a “Monster” receiver as it produces a whopping 160 watts per channel. It incorporates a huge toroidal power transformer. It has the usual dark faceplate as is common with most European versions.  Given that many feel the SX-1250 was the best receiver Pioneer ever produced it stands to reason that the SX-5590 is in a similar position.

  • 30hz and 8khz filters
  • Tape duplicate switch
  • FM muting on/off
  • FM multipath

    1. You must be keeping the power turned down because you will smoke the tweeters in the HPM 100s. I have a pair that I bought new in 1979 and I still have them and use them every day, Great speakers. I would take another pair if I could find some nice ones. I am searching hard for a SX-5590 at the moment. Very rare.I found a couple, probably going to have to bust off the cash, they are not cheep but worth it.

  1. I have an SX 5590. 4 HPM 100s hooked up to it. Nothing out class it, and I have had some expensive amps! have a lot of vintage stereo equipment. Took my marantz turntable to have a belt installed and the tech told me to take the cover home, he didn’t want to brake it

  2. Dear Sir:

    I noticed on the back of the SX-5590 that it had 1200 watts of power! WOW, that’s more than any I’ve seen. How come so much power with only 160wpc? Is this the only difference between the SX-1250? Also, noted there was a hookup for 4 CH, could that be the reason, this receiver does 4 channel as well as the normal 2 for this receiver.


    1. Hi, the 1200 is based on Euro. 220/240. VAC. The USA model SX-1250 would be approximately half for 120 VAC.

      Absolutely no difference between the two other than trim out.

    1. There are a couple guys on Ebay that advertise restoration of the SX-5590, It basically the same as a SX-1250 so im told. Good luck

  3. Just got mine back. FULL upgrade. The tech guru did a meticulous job. He had it hooked up when I picked it up and it sounded incredible. Can’t wait until my friend comes over to help me hook it up. It’s a heavy one. BTW, although rated at 160, it benches 198 Watts per channel.

    1. Owning a 1970s vintage receiver never entered my thoughts ,,.ever ,,..Last year while at a neighborhood sale I ended up leaving with a lawn and garden tractor and a Pioneer 5590 . Upon entering the home I immediately locked eyes on the stereo system though my interest was the 5590 receiver.

      Long story short I’m using the Pioneer 5590 in a home office system using a music server / streamer . The most remarkable aspect of the 5590 is how well it matches driving TeKton Lore speakers ,…..It sounds incredibly good , clean clear and resolving with bass slam that is shocking ! Not a day goes by I ever get board or tired of the the sound I listen to it 7-8 hours a day five days a week .
      This Pioneer receiver is by far one of the finest stereo components I have ever had the pleasure of owning.
