Luckily my dealer let me live with the Millennium for two weeks as I was then able to locate a Krell FPB 300 which by comparison sounded relatively warm and stodgy (and dumped far too much heat into the room)and so I bought the Millennium and lived with it for 3 months before buying a Tact RCS Room Correction Preamplifier and to cut straight to the relevant point.

This isn't the most accurate, dynamic or powerful system you'll ever hear, but man does it sound good. - Car Mechanic

Find the high end shop in your area and get them to let you test it with high end speakers. This is a special product, it does more than the owners here think it can. Garage Service

What can I say is just WOW! I thought it sounded good before, but now it has more clarity and depth. This isn't the most accurate, dynamic or powerful system you'll ever hear, but man does it sound good. | Escondido Concrete And Masonry Pros

Can't say anything since it's excellent!

Haven't heard it as its in for service and recapping. Hoping to match it with a pair of JBL 4211"s and see how it compares with $6000 worth of Onkyo and Jama equipment. BTW the marantz was a freebie and the JBL"s $500. Can't wait to wow the wife.

What is there to say about the 2270 that hasnt already been said? Lol its great! Ive has several of them over the years. I do think they are a bit overrated tho. Good? Yes. Solid? Yes. Versatile? Sure. The 2270 does really good with bass and crisp highs. Has a solid amount of weight to it and has all the controls you could ever want in a receiver

Lacks a bit on the midrange. Solid sould but breaks up a bit when pushed really hard. Power button fails on all of them and its a known fault. Tuner section and phono stage is kind of meh.

pro's : lots of connection options plenty of output power

Contra: no Bluetooth, no remote control.

Grief falls upon me, we have posters thinking this is tubed, we have users hooking this thing to Bose speakers, bet someone out there is trying to push a HDMI cable through the air vents to get their Visio connected.
It has been seen at garage sales, bought at welfare centers and even appeared it trash piles. It bothers me on an almost spiritual level. While I figure that means the built like a tank and will always work no matter where you find it ads were correct, It is disturbing how it is being used.
As in "MY God" do you understand what this thing can do? What it can sound like? Take it down to you local Best Buy (or any mid-fi shop in your area) and ask to hook it up against the best they have.

Ah yes, another review of the Marantz 2270, just what the world needs. Why bother, right? Well, why celebrate holidays or take vacations? For the fun of it, that's why! The 2270 is indeed a special piece of equipment and history. Say what you want, an awful lot of people have taken the time to write about these units, you have to wonder why. My own audiophile journey began back in the 60s with my dads Eico HF-81 vacuum tube amplifier driving Electro-Voice loudspeakers, so it's his fault I have spent all this time thinking about audio equipment.
In the 1970s I read the reviews about the Marantz 2270 and even saw the house fire ad others had mentioned. Unfortunately, a college student who works weekends to go to school can rarely affort the $600.00 asking price (Around $1958.00 in todays dollars) and so made due with other more affordable equipment.
I finally found a used 2270 I could afford in 1992.
Since that time in the 1970s, I have spent considerable listening to a wide variety of units including:
Technics
Scott
Hitachi
Onkyo
Sansui
Dennon
Harman Kardon

Each has had good and bad qualities, and while I still have 3 of them besides the Marantz, the 2270 is the one I spend my valuable time listening to.

Mine has not been restored or upgraded other than replacing the burned out sterio indicator with a LED and resistor to reduce the amount of current and thus reduce the chance of burning out the driver IC. The potentiometers and switches are due for a cleaning as you would expect, but the sound is still excellent.

Regarding power output, according to an old audio magazine I read, the 2270 would have been rated at at least 90 watts RMS by many other manufacturers. Please don't confuse the current idiotic ratings of modern equipment with the 70 watts RMS of these or any of the older Amplifiers or Receivers and consider them underpowered. These units consume roughly 500 watts at full power. My modern home theater system is rated at 600 watts output while only drawing in the same power.

And don't get me wrong, surround sound is fantastic for movies, but most recordings designed for stereo playback are not improved when played over these unit, modifying the sound is for better or worse a form of distortion. I personally find the sound of the Marantz to be clear and uncolored. It performs its job admirably and seemingly effortlessly. Besides the fact that the unit weighs about 40 pounds, just to still be operational after 40 years of use without an overhaul is a testimony to a solid build quality. In addition, they are very attractive units with smooth controls.

A half power bandwidth of 10 to 100,000 cycles per second guarantees solid bass and clear highs. A low TIM reduces listener fatigue and as with most transistor equipment, issues with reactive speaker loads are unlikely due to a solid damping factor.
I have run 2 pair of speakers in the past without the circuit protection kicking in.
Test results in the magazines I read showed higher distortion and reduced power output with low impedance circuits.

When combined with properly placed high fidelity speakers and quality source material, the resulting sound quality is very rewarding indeed.

Should my unit fail, I will most certainly repair it.

There are indeed other companies whose equipment is also excellent and I think they are great too, but I love my Marantz and have informed my family that the only way my receiver is leaving me is when it is pried from my cold dead hands.
