SX1010 Is it the pinnacle of Pioneers Receiver engineering? Maybe it is!!

    No surprise they continued using that front end as long as they did, its a pretty decent building block for a great tuner...

    Forgive me for being honest, but it's a "No" from me. Those pushbutton source selectors are a "Fail" over the long-term in my book. Same problem eliminates some of the SX-XX80 receivers for me. The 1010 does sound great. For my money the SX- X50/XX50 are the Pinnacle for Pioneer engineering. Sound wise for me the SX-737 and SX-828 and the rare SX-2500 fill out the lower power designs that sound good to me . Ymmv.

    Well, thats actually a fair comment about the pushbutton switches, they are a definite failure point, and some them are actually sealed so you cant dismantle them for cleaning like you can with the lever switches.
    The SX XX50 have those push buttons as well, but not as many.
    I have actually drilled holes in the back of some very troublesome pushbutton switches to be able to get contact cleaner into the actual conductor part of the switch.
    But it comes with the age of these units and I would think in another 20 years we'll be cursing those pushbutton switches even more!!

    I've had an SX-1010 since my college days - mid 1970s, when it was brand new. Had it completely overhauled a few years back by a very good tech, who specializes in these units. Never had any problems with the pushbuttons, or any other aspect of this unit. Sounds fabulous and is the one receiver I won't ever be selling (I also have an SX-1250, Yamaha R-1000, Carver 6250 and Carver HR752)... (Playing it even now, with Braun L810s) :music: Great to hear that the OP has discovered this fab receiver...!

    Yes same here kevzep, l think l have seen one 939 and one 1010 for sale here in about three years and l scored the 939 which is about 9.5/10 condition :).

    Yes, three filters and a 4 ganger.

    That is a beautiful looking tuner, reminds me a bit of my Kenwood KT-917.

    I'm not sure why many people seem to have problems with these, l cleaned mine once about three years ago and they are still completely trouble free and silent. They are easy to clean with the faceplate off from the front of the switches.

    I shoot DeOxit & Faderlube in mine yearly when it gets it's clean and Preventive Maintenance done. Never had a problem with either the 1010 or 939 with regard to the push buttons. But I don't punch them 40-50 times to clean them. 20 is sufficient.

    I liked them so much that I bought one many years ago, when no one had money in the US due to the crash of the stock market in 2008. Now everyone is poor in the US.
    The one purchased in 2012 needed low level transistors.
    then two years later needed 2SC1451s.

    Kev: As much as I liked my 1010, I like my 939 more. I feel it's got a slightly smoother sound, with basically the same EQ, preamp/Tone Control boards, but lower powered amp board (mirrored single board vs dual boards of the 1010.) Rated for 70wpc, I had it benched and run thru the FTC tests. It managed 82WPC RIght and 81wpc at clipping into 8ohms, .09%thd @ max. power 20Hz to 20,000Hz. 1kHz wattage was 86 and 85wpc 1 channel driven. This was after a full rebuild except for the outputs. I don't mind the loss of 30watts per as this is my Highest rated unit of all brands I have. I'm using it with Klipsch Heresy's and at 50% on the Volume rattles the windows thruout the house with the doors closed. I listen to it while I'm on the driveway working on the cars. Mainly Goodman, Miller, Shaw, James, Ellington, Basie, etc. from the 30's and 40's. We had a block party last week and I supplied the tunes with it and the Heresy's. The older folks(70's and 80's) loved it and were dancing on the lawn. Had a grand time with it.

    Interesting, I have noticed the 1010 can bite hard at high volumes depending on program.
    A few people feel the 939 is the sweet spot in the receiver line, always good to hear peoples opinions and findings.....I must do some tests on the 1010 when I have a chance...See how it stacks up.
    Thanks for the post, I found it quite interesting and appreciate your views.

    In what regard do you mean bite hard kevzep, do you mean doesn't lack any power?

    It's got plenty of power, but it tends to shrillness, and gets a hard edge to it at near clipping. I've noticed the same thing on the 939, but on the 939 it's a bit less.

    If you are playing something that might be a little bright, it can but your ears.....Its an interesting amp, good recordings sounds amazing, something a bit crap, sounds really crap.....

    Yes totally agree with that....
    I was using it to play my backing tracks when I was practicing my guitar yesterday, and some of the recordings can bring out that shrillness....as I am probably near clipping it at some times ...

    I alternate between my sx1010 and my sx1250. The sound from the 1010 seems a bit warmer than the 1250. I am keeping both. I might like the 1010 a little more than the 1250, though.

    Thanks for the insight guys, very interesting. I have never noticed this with my 939 although l have never really pushed it hard. I would say it is a very smooth and non fatiguing sounding receiver compared to most. I haven't had to push it because it gets plenty loud with 87-90db speakers in a medium sized room :).

    Yes it seems to be just before clipping they do this.....not actually clipping, but running at almost full power...
    Apart from that, smooth as a smooth thing can be........
