Just in case you thought that all my examples were from my portable recorder - only 1 example (the one recorded at Credo) was. The others were done using mics available at the locations - the piano ones were done using Neumannn (can't remember model number).
*** here was a few db of headroom left prior to lighting the soft clipping lights on the amp ***
This is not a reliable indication of whether the amplifier is clipping or not. As you can imagine, short duration clips will not be visible at all.
If you do the maths, a 150w amp on 90dB@1W1m efficiency speakers *will* clip playing back uncompressed recordings with the peaks that I quoted (assuming you are listening from at least 2m away). If you don't believe me stick a CRO on the speaker cable and watch those flattened peaks.
Even my system will clip for peaks greatly exceeding 115dB SPL, and I have a total of over 2000 watts of RMS amplification deployed across 7.1 speakers. A good studio mic will capture up to 130dB SPL, so even I can't play back uncompressed recordings without clipping.
