I realize you need to have the capable hardware, but doesn’t PRAT have a lot to do with the recording? For example, I think the Doors ‘Love Her Madly’ is probably the best example of PRAT I’ve heard so far, Talking Heads ‘Take Me To The River’ is another good one, and Paul Simon’s ‘So Beautiful or So What’ (using XF2-OO tubes). While listening to these songs I can’t multitask – they won’t let me. As a point of reference, I don’t consider Eagles ‘Hotel California’ to have exceptional PRAT, although it’s a decent recording (maybe average PRAT?). On the other hand, there’s a ton of recordings that have very little PRAT (could even be well recorded, but there’s no wow factor). So if someone listens to one of these recording, I’m sure they could get the wrong impression. OP didn’t say what he was listening to, so to me there’s no point of reference. Or am I wrong, are there HP systems that bring PRAT to every single recording no matter how bad it is? Is it possible OP just listened to a recording(s) with bad PRAT.
