Trevor,
Keep the spin coming Trevor.Or is it just dogma?
**I deal in facts. I have used power OP amps many times, over many years.
They're cheap, convenient, easy to use and adequate performers. High end
they ain't.
The Gainclone chip amps were evolved by the former Head of Design at
Luxman.This is the man who dared to make tube amps and low negative
feedback SS amps at Luxman during the 1970s when it was very
unfashionable.[The Duo Beta series of SS amps]
His amp and preamp designs are noted for their ability to image
precisely[relatively anyway], which is something very rare in
mainstream equipment from that era.Clearly he discovered similar traits
with chip amps and this motivated him to start 47 Labs.
**The people behind 47 Labs are niave con-men. The site is full of
nonsensical terminology and outright lies.
These things are not perfect,and the component cost might be low-but
they really do put to shame even expensive and well designed SS amps
when it comes to imaging precision and depth.Especially those with high
damping factors and feedback.
**Sure they probably do, since there are quite a few badly designed
amplifiers on the market. There are also a huge number of properly
designed
amps on the market. Many use the same power OP amps that Gainclones use.
Mostly, they're cheap as chips.

SNIP Hearsay and utter, banal nonsense.
**Here's some gems from those liars at 47 Labs:
a.. World's smallest number of parts - 9 parts per channel ( excluding
attenuators )
a.. World's shortest signal pass length - 32 m/m ( including the length of
parts )
a.. World's shortest NFB loop length - 9 m/m ( including the length of the
resistor )
a.. World's smallest filter/condenser - 1000µF, (50W version - 2200µF)
a.. Rigid and compact aluminum chassis construction to release vibrations
smoothly.
Of course, there's much, much more. Let's not even get into the pricing of
these ridiculous products.

Trevor,
I agree completely with you about the pricing but the hi fi world is
full of products which cost an absurd amount relative to the cost of
their parts or construction.In fact this is almost standard for most
high end products.How about Wilson and Avalon speakers for example?
Similar but more powerful chip amps can be bought as kits for around US
$300 and in this context they are a bargain.
This topic began with a bloke frustrated with not being able to get
decent imaging in his system.
Many people never achieve this in their systems but there is
signifigant anectodal evidence available through forums like this one
that chip amps deliver the goods in this regard.What is most convincing
about this evidence is that many people who make such comments already
have excellent and expensive systems and are not some DIY punter that
has no idea of what good sound is.
I suggested that this bloke might want to try a chip amp as one of
several things to consider in improving imaging on the back of this not
inconsiderable anectdotal experience.It might not help his system or it
might resolve the problem comprehensively.What is the harm in trying it
though?
Why should your opinion and experience count more than others ?
You can justify any position using technical arguements.But are they
the applicable ones?.You might want to take up the cause of Intelligent
Design.-a group of similar mentallity Thought Police.
