I recently sent my MX-1000U in for restoration. I thought it sounded pretty good and looked ok. To my amazement, when I got the amp back, the high frequencies had come alive and were extremely accurate. The stage presence of the midrange was like I haven’t heard before. The low frequency was now very tight and pronounced. It was something I hadn’t realized had deteriorated over time, being the amp is 25+ years old. Also, while it was it was there, I had the incandescent bulbs replaced with LEDs and the old and brittle speaker terminals replaced with 5-way binding posts. The new speaker terminals are very sturdy, a vast improvement over the original setup.
The magnificent work that LegendaryAmps does on the inside does not stop there. The metal cover, the front glass, the rear panel, all exterior components now look new. The amp almost looks as good as it sounds. I am very pleased with the results of the restoration. I absolutely consider it money well spent. It was a pleasure to do business with LegendaryAmps. I appreciated the prompt return of all my emails, and being dealt with honestly.
Words can't describe how I feel right now. I am blown away by the sheer power of this amp. Hooked it up to a pair of Polk SDA SRS using a cx1000u pre amp. Unbelievable. I have NEVER heard a home stereo system sound so pure. And its mine! The sound stage is amazing. What I cant believe is how much sound is produced at just 30 to 40 watts. The amp is beautiful! Fine craftsmanship. I want to personally thank LegendaryAmps for doing what you do. Please do not stop “resurrecting” these magnificent amps.
I have recently come across a couple of these products. The mx-1000 is sounds amazing and is in mint condition. I have is paired with the Yamaha CX-1000 pre-amp. The combination of the two are fabulous and create an amazing sound out of my two amazing Klipsch Chorus speakers. The 1989 yahama engineering master piece, MX-1000/CX-1000 sounds great with modern house/dub step/dance music.
Very smooth and warm sound, it can make cold hard speakers sound musical and alive. All the while, it is punchy and dynamic, very upbeat. Detail rendition is on par with amplifiers in the three to four thousand dollar range. Where I notice the detail is in the bass, which is tight and fast, and in the mid range. It's very smooth and never harsh. It's very clear, it starts and stops, and its easy to get a picture of what is going on in the music. There is a musical color to it, I could compare it to the Russian 2C51 dual triode, but with the MX having less top end and a subjectively flatter response to my ears. This amp runs warm all the time, the idle bias into class A must be pretty high. From what I understand, it is Class A over its entire range and the bias is variable according to the input music. My ears would strongly agree for the power levels I've used it at, over 100W and its still got tons more. To boot, it has 2 massive transformers and 4 capacitors on top, and another 4 underneath and 4 rectifiers! What an overkill designed amplifier. There is a story behind this amp on the web that it was designed to sound like a certain expensive American amp, I would say they succeeded. So the end of this story is I paid $1250 plus Paypal fees on eBay for it in good condition, seen them go higher and waited my turn. No regrets at all.
~Smooth Class A, yet dynamic and punchy
~Power and drive galore, 2 transformers, 4+4 filter caps, 4 rectifiers
~Cost can't be beat
~level controls for different preamps
~meters are useful
~It kind of looks like 1990s, doesn't match the physical look with a tube pre
~None at this price
Early November 2011, checking on eBay for a Yamaha MX-1000 power amplifier, I found a unit that had been fully restored by LEGENDARY AMPS, who was selling the amp in behalf of the owner. I had read online nothing but good things about the MX-1000, and I bought it.
It arrived about two weeks later. The boxing was exactly as described by the other buyers on their feedbacks (like unpacking a brand new item), and the unit, also as stated by the other buyers, looked like brand new. No marks or dents or dings of any kind; the paint of the metal boxing is a solid and uniform black color; the knobs to control the volume on each channel work like for their first time; the acrylic lens protecting the meters panel is in immaculate condition, without a single hair line, and the panel itself is illuminated with a fresh and bright red light. I examined the new speaker ports, which replace the original ones, as I knew it was a regular improvement on the restoration work at LEGENDARY AMPS, and found they are one of the best I have ever seen. And when the power button is pressed down, it’s noticed from there, operation wise, the quality of the restoration work; the click sounds fresh, like for its first time, and the protector comes off after a few seconds in a gently and secure way.
I first played Carly Simon’s Moonlight Serenade album, Columbia CK 9489 (CD). She seemed to be singing right here; next to me, and I heard instruments I have never heard before, not knowing they were on the CD. In one of the pre-bid emails, Skip, LEGENDARY AMPS’ owner, had said that I’d feel the music would come to life. This is absolutely true, the music was alive! Then I played Mozart’s Requiem, Herbert von Karajan, Karajan Gold Collection, Deutsche Grammophon 439 023-2 (CD). The experience was simply superb, as the sound reproduction was bringing to life the full greatness and emotion of this masterwork, vividly and beautifully... I played then Frederic Chopin, Classic Masters Collection, LaserLight 14626 (CD). I was amazed of how real the piano sounded, it was like both, piano and pianist, were in my living room. Then I played Moonlight Serenade, Ray Brown & Laurindo Almeida, Kingston World KN W 2604. It’s a duet between bassist Ray Brown and guitarist Laurindo Almeida. The music is superb; the musical arrangement is from geniuses, and the signal on the CD, as a recording, the technical mix thing, is simply great. If I said the music was alive when I was listening Carly Simon the first day, I was now part of the journey, with the musicians playing in my place with joy and enthusiasm. The amp doesn’t get shy at any moment; it will play all frequencies with no effort, naturally, with authority. And basses are… Boy, they are basses; the amp can go all the way down keeping the natural sound of the instrument all the time, with no distortion at all! The stereo separation is excellent; there is a 3-D effect on the sound that makes the listening experience complete. Some times I have been at the kitchen or another room, and I had to go to the living room to check what was the sound of a certain instrument I just heard, because it seemed to come from somewhere else, knowing, however, it was coming out from my L112s!! It started a process of re-discovery, like listening my CDs for their first time… And, if it happens I’m doing something at the time of playing the MX-1000, there is a big chance I’ll get captured by the music, stopping what I was doing to concentrate just on the beautiful sounds around me…
I started congratulating myself for the purchase, and one month later I bought my second MX-1000 from LEGENDARY AMPS, as they had two units available. The amp arrived early this month, to find the same professionalism and excellence in all aspects of the transaction: communication, packing/boxing, shipping, cosmetics of the unit and, of course, performance. LEGENDARY AMPS’ audiophile skills and thoroughness are remarkable; you even won’t notice any shop-alike smelling when playing your amp… I would say that, more than a stereo amplifier, the MX-1000 seems to be a musical instrument.
Thank you very much, LEGENDARY AMPS’ team!
Equipment used: Sansui CA-3000 preamplifier, Denon DVD 3910 player, Technics SL 1210 M5G turntable with AT 150 MLX cartridge, and a pair of JBL L112 speakers.
