Use a tissue wet with isopropyl alcohol and Q-Tips.Just a quick bystep: How is the thermal paste on the V3 Mono to be changed or (re-)applied without smearing it all over the place (inside) ? I checked on the internet, but nobody, who did it, seem to explain - in detai- l, how he actually did it ???
Anyone with experience wants to answer this question ?
The sound is perfectly neutral like any other modern class D-amp lacking load dependency that probably caused the so-called “harsh” sound of previous generations low cost designs.
This signals to me, that the thermal paste should be applied to the chip or to be exact, to its alu heatsink, and not to the bottom of the alu casing marked by the two screw positions.
Why would you need to know how to change the thermal paste? Are they applying bad or too little of it at the factory giving subpar cooling? Or is this just another trend after opamp rolling or something?Just a quick bystep: How is the thermal paste on the V3 Mono to be changed or (re-)applied without smearing it all over the place (inside) ?

I have several of them already delivered in two charges and don't know, if thermal paste has been applied during production or not. Thus I will have to unmantle them looking for that thermal paste. They seem to be getting rather warm or "hot", as stated by most of the users, who got them already and thermal paste improves coupling temperaturwise
I would say that is an indication the paste is applied. It's transferring heat to the case.
How do You know wihout looking at them opened? Some have received units without or had it only partially applied...
Inverted polarity is not only an issue if you use both outputs (XLR and RCA) assuming inverted polarity between them.
That makes no sense at all. Maybe I’m just stupid.
That might be true if there were any consistency in absolute phase of recorded music, but there isn't. If it's something you care about then you need a phase switch somewhere in your system to let you change it on a per-recording or even per-track basis.
See the contribution of @NTK earlier in this thread.
Still makes no sense. Someone needs to draw me a picture illustrating this asymmetry.
See #2853 in this thread by NTK. He responded to my question on this topic with some interesting articles.
There's a whole thread about it. Any discussion of phase/polarity in general really belongs there not here.
Some evidence of the lack of consistency in recording phase/polarity by record label, showing a fairly even split. Note the use of 'predominant' in there - it's not even consistent for all releases on a given label.
Yes - inverting the output in the Flex will do the same as swapping the speaker connections. Also your SVS sub will almost certainly have a phase switch or knob because it's a normal thing to check when setting up a sub, probably described in the SVS manual. If you've got the frequency and slope of the sub crossover correct then incorrect phase will show as a big dip at the crossover frequency, while correct phase would have a flat response, or at least flatter. You might be unlucky and have a room response null at crossover frequency, in which case it may be hard to spot the difference.
There's been at least one report of one unit being hotter than the other but I didn't see any follow up. The cooler one likely did not have paste. Open it. But you better have paste on hand to replace it from opening it. Mine are very warm and I don't suspect missing paste.
