I always see ads and discussions about single-channel basic power amps often calling them "monoblocks". But I never see a stereo power amp being called a "stereoblock". Why? (Both terms seem silly to me.)

Note: This post was inspired by but not specifically directed toward a recent post about a monophonic amplifier.

I've wondered the same thing myself, if "monoblock", why not "stereoblock".

I think some people use terms like "monoblock" to show that they are "real" audiophiles and in the know. It seems to be part of the pompousness of audiophilism.

Dave, "monoblock" just infuriates me! I refuse to use that Audiophile term. It is a basic amplifier; no preamplifier. If you look at all of the vintage catalogs, you will NOT see that silly corksniffer term.

BTW, the algorithms of the forum "corrected" the term that I used above! I did not type "Audiophile"!

Sounds more impressive than 1.0. Two monoblocks would be 2.0. But three monoblocks 2.1.

I just call them "power amps", stereo or mono.

Yes, because that is what they are. "Monoblock" is a keyboard commando term that was coined by a certain "Audio" group. Maybe it just sounds neat to them. To me, it sounds stupid.

I thought the descriptor "monoblock" came into vogue in the 80's when a single style mono amplifier was required to drive a sub-woofer speaker in a car and then later, for the home sub-woofer speaker.

The 80's also gave us the portable radio descriptor, "Boom Box"

And big hair :mrgreen:

I have been heavily involved in the sound equipment world for over 44 years. I started my audio engineering as an intern within a performing arts theater center. Theater and studio sound was my world for a decade, until broadcast service field engineering called. Audio was and still is a favorite pastime.

IIRC, I first heard the term "monobloc" while reading a British hifi magazine, circa late 1970s. At that time, I was already using mono tube amps for each stereo channel. The separate, mono power supplies for each channel always yield "better" sound than a stereo, single power supply amp, IMHO.

With the UK spelling of monobloc, it was simply a matter of time for the USA to adapt the spelling monoblock.
Silly semantics, it's just another way of saying mono amp...

I resist using the term audiophile, as it seems to have become a negative connotation. While this term simply means audio enthusiast, too many people seem to believe audiophiles are snooty. Some may be...but, I will always be proud of my "sound man" heritage.

I have much the same background, and always have called them "power amps"; that is, an amplifier without any low level stages or tone controls. An amplifier such as the Eico HF-20 would be more properly referred to as an "integrated amp".

I wonder if that '60s TV commercial for the Rock 'em Sock 'em, boxing Robots was the inspiration for the 'bloc term...

"...knock your 'blocks off"...

the term "power amplifier" makes the most sense imo.

"knock your block off" is an expression that goes back at least to the early 20th century or perhaps even the late 19th century, it's been around a looong time. Doubt it has any relationship here.

Does a basic mono amp have to have high power to be called a monoblock? Can a single-ended 6V6 driven by a 6J5 be called a monoblock?

Back in the 80's, big and loud car audio was the rage. In Jersey, a car with big audio especially driving the sub woofer, you could hear coming before you actually saw the car. The mono amplifiers were all high power solid-state (anywhere from 1000 to 10,000 watts RMS) and looked like a block hence the name monoblock.

As the new generation came into prominence :mrgreen: they started calling all mono tube and solid-state amplifiers monoblocks. This is the same generation that starts every response to a question with the word "So" :D

But wait: Amateur radio operators aren't immune to this gashing of English words.

All of our VHF and UHF solid-state amplifiers are called "BRICKS" :D

And don't forget the term "boatanchor"; once used in a derogatory way, but now has respect among some of us.

Of course we did: in Audiophile terminology they are called "Dual Mono" amps. (usually meaning there's a separate power transformer and/or power supply for each channel housed into a single stereo chassis)
