Hi Guys,
I hear and read about reference grade amps quite a lot e.g. Marantz have a separate line of reference products. May anyone please guide what is exactly a reference grade and any perceptible differences from normal amps and why they cost a lot above
Let me start by setting the tone for "Reference grade".
What is "Reference grade"?
"Reference grade" indicates a
superlative quality. It promises a
very high level of performance. It promises an
ideal behavior.
What "Reference grade" isn't?
It isn't an absolute line. It isn't a guarantee of a certain level or performance. Because there are no established performance rules in the audio world to begin with. It isn't a clear line on one side of which all components are not-reference grade and on other side all reference-grade.
"Reference grade" also isn't a ticket to obnoxious price tags. It certainly isn't a means to cheat people out of their hard earned money. However, in real life the usage of the term "Reference grade" is very loose. So loose that it is mostly misused than used correctly.
Getting off the theory, if I were to choose some components that I have (personally) found to be reference grade and can recommend anyone - it will have to begin with the same Marantz reference grade components you mention. The Marantz amps are very highly underrated. The reason lies in people's mindset. People often relate reference grade with price tag rather than actual performance.
Some other Manufacturers I can associate with "Reference grade" would be - Goldmund, Macintosh, Gryphon, Accuphase, Luxman, Pass Labs, Threshold etc. Please note the list is not comprehensive by any means.
Perceptible difference are obvious to anyone with an open mind. When you hear a reference grade setup (not a component alone) you immediately recognize things you never thought possible (unless the person indeed has an unevolved listening ability). The point I am trying to make is - one needs to have an open mind and some "
listening ability" (vs habit of hearing casually/inattentively) to be able to perceive the difference.
Reference grade components cost a lot due to increased production cost. Reference grade components are built to
very tight tolerances which causes production cost to climb up. Reference grade components also take a lot of research before getting approved for production. The "
cost-to-develop" is way higher for reference grade components. So is the post-production issues. Reference grade components have a comparatively much smaller market. They need much more specialized marketing, distribution, and supply-chain. Consequently, it adds to their cost at each step.
So there are valid reasons why reference grade components cost a lot. Though there is no dearth of companies trying to play with the buyer's mindset by misusing the term and put the label on their offerings in order to add a premium on the price.
