A typical GC if for beginners, but even that is a very good sounding amp.
There are many variants though, and it's possible to make a very very very good sounding amp with LM chips.
It can sound exotic, expen$ive, frightening with all that detail.

Ah! Common Peter, post links to reviews of your amps, I'd like to read them, and I'm sure you know all the links by heart .

Hi. I have built the Leach low tim and Brians GC.
My Leach amp is now sitting under my bed. It seems to be missing the lower octave. This seems to be a issue with the Leach. Maybe because I used MJL3281a and its compliment.
I dont know why?
The Gainclone sounded very good with out any adjusting and was very easy to build.
I do have a hum with the G.C. that comes and goes. I must try changing the grounding.
At this point I think the G.C. has a better balanced sound.
If any one has an idea of why the leach amp is missing some bass I would like to hear it. I used it for a while as a sub amp and it put out the power but on my 3 ways not the same as the G.C or my Sumo amp.
Thanks Steve.

I hope that this excellent post by Pedja doesn't pass unnoticed.
Everyone should read it.

I (we) usually generalize that these are very good sounding chips, very good amps, etc.
One can take an LM chip (any of these) and make bad sounding amp.
Guys, don't think it's only the chip that makes the amp.
It's much more than that, it's everything.

u are asking whats better a chip amp or a solid state amp in the chip amp forum , its like going to the ferrari forum and asking what is the best car

u should check it yourself and see what u like more .imho if everything is ok with the construction there should be no audible difference at all , but thats just me

How is that going to be any different than asking on the SS forum if the SS amp is better than the chip amp ? Although I was going to post there also to listen to that side of the arguments.
Anyway, thanks for the link. Looks like BobEllis did not use BrianGT's PCBs so the missing piece of information is that the pcb was indeed a good design(or otherwise) and free of things that can make a GC sound bad.
