Random thought: Rephrasing

You have a device running on 115V.

When you use it with a step-down transformer, you worry about the negative impact of the step-down transformer.

But when you use it with an isolation transformer that also does 230V -> 115V, you start hearing the improvements.

Note that some step-down transformers are autotransformers which do not offer isolation. However the step-down transformer inside your consumer equipment is almost always isolated.

PSP (fat) RMAA measurements

This is a bit late (okay, a lot late), but here are the RMAA results for the first PSP.

PSP max volume unloaded
PSP max volume 33Ω

(Ignore the crosstalk measurements because they are wrong!)

Unloaded

33Ω

Because I want to see if I'm going to get an improvement with what I'm going to do.

Oh, and the output impedance is about 15.8Ω. Kinda high for some earphones. My X10 sounds like this:

TMPGEnc Video Mastering Works 5

Ok, so I don't know when to call it a review and when to call it a quick look, so screw the concept, everything will be called reviews regardless of how good or rubbish they are. So I've joined the masses of creators of bad reviews.

Continuing from the previous review, I have decided to make x264 (but not Mediacoder!) the winner instead of MainConcept encoder used in TMPGEnc XPress.
