Most of people in this thread owning the amp seem to like it, which must be for a reason. I like it driving my system, too. So please save yourself the "closer look" if you find it blurring the music. About the LA90, maybe it does not have enough power for my speakers.
Please forgive me for interfering and ignore my comments.
...check your impression ears-only to see if that's the issue before chasing more equipment.
Uh huh.
Why bother chasing your imagination? You can't be bothered to do a cursory listening test.
If you mean me, it has nothing to do with it at all. It's about the circuit used, not the power supply.
Look at the datasheets. Note the effect of rail voltage on distortion and noise.
Do you have any data that shows what that circuit does to the audio. Measurements, for example. Better still, measurements of the actual amplifier in question, showing the effects on the audio output from the amp.
It's not worth the trouble. There have been enough publications on the subject for decades, not only from TI.
So your assertions don't seem very well evidenced. I'll pay them as much attention as that warrants.
The HRP series all seem to be external power supplies but also EPP. Perhaps you could link to a suitable one.
You can find the Mean Well HRP series immediately via Google, you only have to choose the power and voltage. But they are open frame power supplies, you should know that and have the skills to use them, otherwise it's dangerous.
This is, frankly, a dishonest reading.
