But still the (much) more powerfull amp has the advantage of more current capability

I must repeat myself, this is not a fair test.

The snag with commercial units is that one has to buy the hardware/profit/R&D etc. as well!
This is non-sense, particularly in DIY forum...

People approach DIY not only for budget reasons but also to have things done exactly like they want, free of manifacturers cost oriented design choices.

The $70-100 dollars budget is different between you and the manifacturer.
  1. the manifacturer pays much less parts, since it buy them in quantities.
  2. you don't pay the manifacturing cost but retail price.

I recently discovered my ability to hear the full audio spectrum has changed due to the natural ageing process. A poster on the MyRef FE project suggested a standardized set of speakers for the beta builders – which I heartily endorsed – got little to no support. When the various room characteristics are necessarily included in the equation, things get even messier.

We all could add to the list of variables for days so I won’t even try to be definitive. I’m beginning to believe that the book title from the 60s really applies to the audio world – “When you meet the Guru in the middle of the road, run the other way.” That doesn’t diminish or challenge the honesty/validity of ones stated impressions. There just doesn’t appear to be a one size fits all – either sonically or with lab tools - method in an area that in its very nature is at least half artistic.

I think the best we can do is use the terms we have to report what each of us experience/prefer (with as complete a description of limiting elements as is practical), and leave the determination of “Best” to those would enjoy calculating Pi to “Infinity and Beyond”.
+1 :-)
