How much does an amp circuity design affect sound?

[Geoffcin]

I would say that different designs contribute greatly to a different sound. However, the basics of amplification architecture have been well developed for the past 40-50 years, and most modern designs are based on these well worn models. Some designs like the Tri-Path and ICE based amps are relatively new, and the Halcro amps uses a propriatary design, but most of what else is out there are based on tried-and-true designs.

Great points. One side note, I didn't make my points initially very clear. I was trying to summarize the research that I had done about the quality of the lower end Chinese audio products vs the DIY option that I decided to go with.

In that regard, what impact does a 'famous' audio design have on sound quality versus quality components. My conclusions is that the older designs are very solid but that newer designs are better and that lower end components detract from the sound as well.

BTW: the higher end Chinese options I'm really intrigued with. They seem to be some very solid products.

I think your conclusions are very reasonable, Stan, especially on the quality issue. Bear in mind the board layout as well as quality of components can also effect sound.

Nevertheless one wonders how much tube designs have really improved. I've heard that higher quality components are available today, so that might effect the designs, (just speculation on my part). Board layout is critical especially for digital and class D modules, but maybe less so for tube stuff.
