Topping G5 Review (Portable DAC & HP Amp)

[mike7877]

Ok, cool, you've described how the unit works in terms of power delivery but you've not explained how you "over volted" it? I quick checked your longer post with the pics and couldn't really see how you'd "over volted" it. You don't have to go into mega depth - what did you do replace some internal components, re route something, use a different power source, what?

My bad, somehow at least a few sentences are missing...

I gave, to the G5's analog input, somewhere between 5 and 10V AC RMS (in the form of music..) for not very long - not even a song. Probably not even a verse.

What isn't missing, but I'll add for clarity here, is, I showed how the lowest gain setting of -8dB, and the analog out from the DAC being 2.1V, suggests 5.2V should be safe (neutralizing the -8dB takes 2.5x the voltage, or 2.5x 2.1). If you don[t want to take chances, 2.1V will be safe. Most things can't provide more than 2.1V single ended anyway (unless they're amps) so it's not a huge problem for most people.
..just me because mine's broken now lol

Ah, I understand how you did it now (how you burnt out your G5). I was just trying to find some specs re the Line In on the G5, and I came up with this:

So for the red circled bit does that mean that 5.8V input is safe? 5.8V when using Low Gain, 4V when using Medium Gain, 1.9V when using High Gain?

Seriously, a swollen battery after 8 months? No I have not left it on a charger!

I wish it had built in PEQ

I wish it had a battery level indicator, reconstruction filter selection and better EMI protection at least.

I long for a Topping G5 Mk.2

Ideally with a simple display.
